  2. The Koh-i-Noor diamond remains one of the most disputed jewels in history, with multiple countries claiming ownership. The governments of India, Pakistan, Iran, and Afghanistan have all demanded its return, arguing that it was taken unfairly during British colonial rule. The debate over the Koh-i-Noor continues, with many viewing it as a symbol of colonial exploitation.
    • India's Claim - India has repeatedly requested the return of the Koh-i-Noor, especially after gaining independence in 1947. Many Indians believe the diamond was looted by the British after the Second Anglo-Sikh War in 1849. The Indian government has made formal appeals, but the British government insists it was acquired legally under the Treaty of Lahore.
    • Pakistan's Claim - Pakistan argues that the diamond belonged to the Sikh Empire, which ruled parts of present-day Pakistan. Since Maharaja Duleep Singh, the last Sikh ruler, was forced to hand over the diamond to the British, Pakistan claims it should be returned to Lahore, where the Sikh Empire was based.
    • Afghanistan's Claim - Afghanistan asserts that the Koh-i-Noor was once in the possession of Nader Shah, the Persian ruler who invaded India in 1739. Since the diamond passed through Afghan rulers before reaching the Sikh Empire, Afghanistan believes it has a rightful claim.
    • Iran's Claim - Iran also claims ownership, citing its historical connection to Nader Shah, who took the diamond from the Mughal Empire. Iran argues that since the diamond was originally in Persian hands, it should be returned.
    • British Response - The British government has consistently rejected all claims, stating that the diamond was legally obtained and is now part of the Crown Jewels. It remains set in the Crown of Queen Elizabeth The Queen Mother, displayed in the Tower of London.
  3. The Koh-i-Noor diamond, meaning "Mountain of Light," is one of the most famous and controversial diamonds in history. It was originally mined in India, likely from the Kollur Mine in present-day Andhra Pradesh. Today, the Koh-i-Noor is set in the Crown of Queen Elizabeth The Queen Mother and is displayed in the Tower of London.
    • Early History - The diamond's exact origins are unclear, but it was first recorded in the Mughal Empire. It was part of the Mughal Peacock Throne, a lavish throne adorned with precious gems. In 1739, Persian ruler Nader Shah invaded Delhi and took the diamond, giving it its famous name.
    • Changing Hands - Over the centuries, the Koh-i-Noor passed through various rulers, including the Afghan Durrani dynasty and the Sikh Empire. In 1849, after the Second Anglo-Sikh War, the British East India Company took possession of the diamond and presented it to Queen Victoria.
    • British Royal Jewel - The diamond was displayed at the Great Exhibition in London in 1851, but its original cut failed to impress. Prince Albert, Queen Victoria's husband, ordered it to be re-cut into an oval brilliant shape. Since then, it has been worn exclusively by female members of the British royal family, as it is believed to bring bad luck to male wearers.
    • Controversy and Ownership Disputes - The governments of India, Pakistan, Iran, and Afghanistan have all claimed ownership of the Koh-i-Noor, demanding its return since India's independence in 1947. However, the British government insists it was obtained legally under the Treaty of Lahore in 1849.
  4. Diamonds are prized for their beauty, rarity, and staggering price tags. Red diamonds are the rarest of all colored diamonds, followed by pink and blue. Their scarcity and unique hues make them highly sought after by collectors and investors. Koh-I-Noor, The Cullinan Diamond, The Hope Diamond, De Beers Centenary Diamond, Pink Star Diamond, Oppenheimer Blue, Moussaieff Red Diamond, and Cullinan Diamond are the most expensive and rare diamonds in the world.

  6. Platinum and gold are both precious metals with unique properties and uses; while gold is known for its rich yellow color, more abundant and has been valued for thousands of years, platinum has a white-silver hue and is rarer than gold, making it more expensive in general. Gold is softer and less dense than platinum, and is often alloyed with other metals to increase its strength, especially in jewelry, while platinum is denser and more durable than gold, making it highly resistant to wear and tarnish.
  7. Gold and diamonds are major global commodities, with different countries leading in reserves and production. The United States holds the largest official gold reserves at 8,133.5 tonnes, followed by Germany (3,351.5 tonnes), Italy (2,451.8 tonnes), France (2,437.0 tonnes), Russia (2,333.0 tonnes), China (2,279.6 tonnes), Switzerland (1,039.9 tonnes), India (876.2 tonnes), Japan (846.0 tonnes), and the Netherlands (612.0 tonnes). These reserves serve as a hedge against economic uncertainty. On the diamond front, Russia leads with 37.3 million carats produced annually, followed by Botswana (25.1 million carats), Canada (16.0 million carats), Angola (9.8 million carats), the Democratic Republic of Congo (8.3 million carats), South Africa (5.9 million carats), Zimbabwe (4.9 million carats), Namibia (2.4 million carats), Sierra Leone (0.5 million carats), and Lesotho (0.47 million carats). While Russia dominates in both gold reserves and diamond volume, Botswana is renowned for high-quality gem diamonds, making these nations key players in the global luxury and industrial markets.
  8. Gold is widely used in jewelry, electronics, dentistry, and as a monetary asset; platinum is used in jewelry, automotive catalytic converters, medical instruments, and certain industrial applications due to its high melting point and corrosion resistance.
  9. Gold and platinum are prized for their distinct physical properties and versatile applications. Gold, with its malleability, conductivity, and resistance to corrosion, is widely used in jewelry, electronics, dentistry, and as a reliable store of monetary value. Platinum, known for its high melting point and stability, plays a crucial role in automotive catalytic converters, medical instruments, industrial equipment, and premium jewelry, thanks to its durability and sleek appearance. Together, these metals bridge luxury and utility across multiple industries.
  10. Gold prices can be more volatile but it remains a popular investment as a hedge against inflation and economic uncertainty while platinum is more expensive but its market can be influenced by its industrial demand, which ties to the automotive sector.
  11. South Africa is the world's leading producer of platinum, accounting for about 68.32% of global production, following by Russia contributing around 15.52%, Zimbabwe producing about 8%, Canada with around 4.47% and the United States contributing about 2.26% of the world's platinum.
  12. The country with the most gold reserves is the United States, holding approximately 8,133.46 tonnes of gold valued at around $687.73 billion, following by Germany, Italy, France, China, and Switzerland which hold 3,351.53 tonne, 2,451.84 tonnes, 2,436.94 tonnes, 2,264.32 tonnes, and 1,039.94 tonnes respectively.
  13. Since gold often maintains its value over time and can act as a hedge against inflation, investing in gold has been a popular choice for centuries; during economic or geopolitical uncertainty investors often turn to gold as a safe haven.
  14. The £3.5 million Diamond Bra, known as the Hearts on Fire Diamond Fantasy Bra, was crafted by Victoria’s Secret and unveiled in 2006. This dazzling creation featured 2,000 perfectly cut diamonds totaling over 800 carats, including a 10-carat diamond brooch shaped like a Victorian flower. Despite its extravagant weight and sparkle, model Karolina Kurkova described it as surprisingly comfortable—proof that luxury and wearability can coexist, even in the world of gem-encrusted lingerie.
  15. Diamonds have a high intrinsic value and can be a good store of wealth; however, their prices can be volatile and are influenced by factors such as supply and demand, economic conditions, and trends. The diamond market is less liquid compared to other investment options like stocks or gold.
  16. Diamonds symbolize eternal love, purity, and strength, making them popular for engagement rings and significant life events. The brilliance, rarity, and enduring nature of diamonds make them a fitting symbol of eternal love and commitment, and perfect for marking special occasions and milestones.
  17. Russia, Botswana and Canada are the top countries having the most diamonds. Russia is the world's largest producer and exporter of rough diamonds, mining close to 42 million carats while Botswana is producing around 24.8 million carats and Canada around 16.2 million carats annually. The majority of Russia's diamond production comes from the Siberian region of Yakutia, where the largest diamond mine in the world is located.
  18. The most expensive piece of jewelry ever sold is the Pink Star Diamond, which fetched a staggering $71.2 million at a Sotheby's auction in Hong Kong in 2017. This 59.6-carat diamond, which is currently owned by Chow Tai Fook Enterprises in Hong Kong, is renowned for its exceptional color and clarity, making it one of the rarest and most valuable diamonds in the world.
  19. The Pink Star Diamond, mined by De Beers in Africa in 1999, is a spectacular 59.6-carat gemstone renowned for its mesmerizing color and flawless clarity. After a meticulous two-year process of cutting and polishing, it emerged as one of the largest and most exquisite vivid pink diamonds ever uncovered, setting a new standard in the world of rare gemstones and captivating collectors across the globe.
  20. Platinum is among the rarest and most expensive of the popular precious metals. It is an extremely rare metal occurring at a concentration of only 0.005 ppm (parts per million) in Earth's crust It is rarer and more expensive than gold. Platinum, which was named 'platina', meaning 'little silver', is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Platinum is used for jewellery and many other areas, such as dentistry, as a catalyst in petroleum refining, anti-pollution devices (automobile and industry), electronics, and pharmaceuticals when a substitute is not available as it is very rare, or for prestige.

    • The Imperial State Crown, crafted in 1937 for King George VI, stands 31.5 cm tall and weighs approximately 1.06 kg (2.3 pounds), adorned with over 3,000 precious stones including 2,868 diamonds, 269 pearls, 17 sapphires, 11 emeralds, and 5 rubies. Among its most storied gems are the 317-carat Cullinan II diamond, known as the Second Star of Africa, prominently set at the front; the 170-carat Black Prince's Ruby, actually a red spinel with a royal and battle-worn legacy dating back to Edward of Woodstock and Henry V; and the 104-carat Stuart Sapphire, a deep blue gem once belonging to the exiled Stuart dynasty, now resting at the back of the crown. These historic stones weave together centuries of monarchy, conflict, and regalia into one spectacular symbol of royal heritage.
  24. The word "diamond" originates from the ancient Greek word “adamas” (ἀδάμας), which means unbreakable, invincible, or indestructible. This name was chosen to reflect the extraordinary hardness of diamonds—the hardest known natural material on Earth. Over time, “adamas” evolved through Latin as adamantem, then Old French diamant, and finally into the English “diamond.” The term also carried metaphoric weight in ancient cultures, symbolizing strength, purity, and permanence.
  25. As of 2024 and 2025, the United States holds the world's largest gold reserves at 8,133.5 tonnes, comprising 71.3% of its foreign reserves, followed by Germany with 3,351.3 tonnes (73.0%), the IMF with 2,814.1 tonnes, Italy with 2,452.0 tonnes (69.6%), and France with 2,437.0 tonnes (71.2%).

  27. The Graves Supercomplication, crafted by Patek Philippe for American banker Henry Graves Jr., was sold at auction in Geneva on November 12, 2014 for a record-breaking 20.6 million Swiss francs (£13.4 million). Commissioned in 1925 and delivered in 1933, the watch took eight years to complete and was made from 18-karat gold, not 24-karat as sometimes misstated. Weighing approximately 536 grams (1.18 pounds), it features 24 complications, including a perpetual calendar, Westminster chimes, sunrise and sunset times, and a celestial map of the night sky above Graves’s New York apartment2. It remains the most complicated mechanical watch ever made without computer assistance.
  28. In 2024, China led global gold consumption with 985.3 metric tons, followed by India with 802.8 tons, while Vietnam and Thailand consumed 55.3 and 48.8 tons respectively. Moving into 2025, India's demand is projected to range between 700 and 800 metric tons, influenced by high prices; China's consumption dropped significantly to 290.5 tons in the first quarter alone; Thailand saw 9.1 tons in Q1, continuing its upward investment trend; and Vietnam is estimated to reach 28 tons for the first half of the year, bolstered by strong retail demand.
  29. In 2012 India consumed 864.2 metric tons of gold compared with 776.1 tons in China, 80.9 tons in Thailand, and 77 tons in Vietnam.
  30. The Shirley Temple Blue Diamond, a 9.54-carat "Fancy Deep Blue" gem, was purchased by the actress’s father in 1940 for $7,210 to mark her 12th birthday and the premiere of her film The Blue Bird. Though it was estimated to fetch between $25 million and $35 million at a Sotheby’s auction in 2016, bidding stalled at $22 million—below the reserve price—so it didn’t sell2. Despite this, the diamond remains one of the most iconic colored stones, prized for its rarity, provenance, and deep blue hue.
  31. Diamond, the hardest natural material known, ranks 10 on the Mohs scale and is widely used for industrial cutting, grinding, and polishing tools. Roughly 80% of all mined diamonds are not suitable for jewelry due to lack of clarity, color, or size and are instead reserved for industrial applications. Most diamonds formed deep within Earth’s mantle under intense heat and pressure are estimated to be between 1 to 3 billion years old. About 65% of the world’s diamonds are sourced from southern Africa, with countries like Botswana, South Africa, Namibia, Angola, and the Democratic Republic of Congo playing key roles in global diamond production and trade.
  32. Diamonds have been known in India for over 6,000 years, initially treasured as religious icons and symbols of divine power. India was the earliest source of diamonds until Brazil's discovery in 1725, when miners unearthed stones along the Jequitinhonha River, shifting the global supply. Today, the world’s leading diamond producers are Africa, Russia, Botswana, Australia, and Canada, with Russia mining over 37 million carats in 2023 and Botswana home to the richest mine, Jwaneng. Despite not producing diamonds domestically, the United States remains the largest diamond market, accounting for more than 45% of global retail demand, driven by luxury branding, consumer culture, and major industry hubs like New York’s Diamond District.
  33. Synthetic and natural diamonds differ primarily in origin, rarity, and market value: natural diamonds form deep within the Earth over billions of years under extreme pressure and heat, often containing unique inclusions and color variations, while synthetic diamonds are created in laboratories within weeks using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods, resulting in stones with fewer imperfections and controlled color. Both types share identical chemical composition and hardness (10 on the Mohs scale), but natural diamonds typically retain higher resale value due to their geological rarity and cultural prestige, whereas synthetic diamonds are 20–90% more affordable, environmentally friendlier, and ethically sourced, making them increasingly popular among modern consumers
  34. Each year, approximately 26,000 kilograms (57,000 pounds) of diamonds are mined globally, which translates to about 130 million carats. These diamonds come from major producers like Russia, Botswana, Canada, and South Africa, and are valued at nearly $9 billion annually. While diamonds are often associated with luxury and romance, a significant portion is also used for industrial purposes due to their unmatched hardness.
  35. Discovered on January 26, 1905, at the Premier Mine in South Africa, the Cullinan Diamond remains the largest gem-quality rough diamond ever found, weighing an astonishing 3,106.75 carats (621.35 grams or 1.37 pounds) and measuring approximately 10.5 cm (4.1 inches) in its longest dimension2. Named after Sir Thomas Cullinan, the mine’s owner, this massive stone was later gifted to King Edward VII and cut into nine major diamonds and dozens of smaller gems, with the largest—Cullinan I, or the Great Star of Africa—weighing 530.2 carats and now set in the Sovereign’s Sceptre as part of the British Crown Jewels.
  36. The Tiffany Yellow Diamond was discovered in 1877 at the Kimberley Mine in South Africa, initially weighing an astounding 287.42 carats (57.484 grams) in its rough form. Purchased a year later by Charles Lewis Tiffany for $18,000, it was sent to Paris where gemologist George Frederick Kunz oversaw its transformation into a magnificent 128.54-carat cushion-cut gem with 82 expertly placed facets to enhance its brilliance and fire. Now one of the largest and most famous fancy yellow diamonds in the world, it remains a centerpiece of Tiffany & Co.'s legacy and has been worn by select celebrities on rare and glamorous occasions.
  37. The terms “carat” and “karat” may sound similar but refer to different measures: a carat (ct) is a unit of weight used for gemstones, equal to 200 milligrams, and remains the global standard for measuring diamonds and other precious stones, while a karat (kt) indicates the purity of gold, with 24kt signifying pure gold. Although 24kt gold contains nearly 100% gold, it is the softest and least durable form, making it a poor choice for everyday jewelry, which is why lower karat alloys like 14kt and 18kt—blended with harder metals such as copper, silver, or nickel—are typically preferred for wearability and strength.
  38. Gold purity is measured in karats, with each level representing a specific percentage of gold content: 8kt gold contains approximately 33.48%, 10kt has around 41.81%, 14kt includes 58.48%, and 18kt features about 75.15% gold. Rarely used 19kt gold has 79.31% purity, while 22kt gold appears in two standards—90% for coinage and 92% for traditional jewelry. At the top of the scale, 24kt gold is considered pure, containing 99.9–100% gold, although its softness makes it less suitable for everyday wear.
  39. Gold alloys are created by mixing pure gold with other metals to achieve various colors and properties. For yellow gold, 18kt consists of 75% gold, 12.5% silver, and 12.5% copper, while 14kt contains 58.5% gold, 25% silver, and 17% copper. White gold blends 75% gold with 5% copper, 15% nickel, and 5% zinc in 18kt form, whereas the 14kt version includes 58.5% gold, 20% copper, 14.5% nickel, and 7.5% zinc. Rose gold gets its distinctive pink hue from higher copper content—18kt rose gold has 75% gold, 2.75–5% silver, and 20–22.25% copper, and 14kt rose gold is composed of 58.5% gold, roughly 8–10% silver, and about 32–33.5% copper. These mixtures vary slightly by manufacturer but follow standard proportions to achieve their unique colors and characteristics. A summary is provided below
    • Contents of gold made in other colors - 18kt yellow gold: 75% gold + 12.5% silver + 12.5% copper; 14kt yellow gold: 58% gold + 25% silver + 17% copper; 18kt white gold: 75% gold + 5% copper + 15% nickel + 5% zinc; 14kt white gold: 58% gold + 20% copper + 14.5% nickel + 7.5% zinc; 18kt rose gold: 75% gold + 5% silver + 20% copper; and 14kt rose gold: 58% gold + 10% silver + 32% copper.
  40. In contrast to the 11% drop in gold prices in 2015 caused by a strengthening US dollar, both 2024 and 2025 saw historic highs followed by market corrections. In 2024, gold surged above $2,472 per ounce in August, fueled by geopolitical tensions, central bank purchases, and economic uncertainty, before settling around $2,441—marking a gain of over $500 from the previous year. Continuing that trend, gold peaked at $3,500 per ounce in April 2025 before dipping to $3,283 in July as profit-taking, a stronger dollar, and easing safe-haven demand tempered the rally.
  41. Gold is the only naturally metal material that is not chemically affected by air, moisture and most corrosive reagents. Gold is one of the least reactive elements in nature, making it uniquely resistant to corrosion and tarnish. It doesn’t react with oxygen, moisture, or most acids and alkalis, which is why it remains chemically unaffected by air and water—even in harsh environments. This exceptional stability stems from its high ionization energy and tightly packed atomic structure, placing it among the noble metals. While most metals oxidize or corrode over time, pure gold retains its luster indefinitely, making it ideal for jewelry, electronics, and currency. Only a few substances, like aqua regia (a mix of nitric and hydrochloric acid), can dissolve it.
  42. Since overtaking South Africa in 2008, China has remained the world’s largest gold producer, yielding 380 metric tons in 2024—around 11.5% of global output—and beginning 2025 with 87.24 metric tons produced in the first quarter. In contrast, South Africa’s gold production has continued to decline, with just 100 metric tons mined in 2024 and a 2.5% drop in April 2025, as it grapples with deep mine operations, energy challenges, and aging infrastructure.
  43. Gold, platinum, and copper are all exceptionally ductile metals, capable of being stretched into long, thin wires without breaking due to their face-centered cubic (FCC) crystal structures, which allow atoms to shift easily across planes. Gold leads in ductility—a single gram can be drawn into a wire over 3 kilometers long, and an ounce can extend up to 60 miles. Platinum comes close, frequently used in high-precision components like electrical contacts and catalytic converters. Copper, though slightly less ductile, remains highly flexible and is widely used in electrical wiring for its outstanding conductivity and ease of refinement. This remarkable ductility makes all three metals indispensable in industries spanning from electronics to aerospace.
  44. Gold is famously ductile—meaning it can be stretched into incredibly thin wires without breaking. In fact, a single troy ounce of pure gold (about 31.1 grams) can be drawn into a wire up to 60 miles (nearly 100 kilometers) long, with a diameter of just a few microns. This remarkable property makes gold ideal for high-precision electronics, especially in microcircuits and aerospace applications where reliability is critical.
  45. As of 2025, approximately 216,265 metric tons of gold have been extracted from the Earth’s underground and riverbeds—a dramatic increase from the earlier estimate of 88,000 tons—thanks to technological advances and large-scale mining after 1950, which accounts for nearly two-thirds of the total. To visualize it, all the gold ever mined would fit into a cube about 22 meters (72 feet) per side, and since gold is virtually indestructible, almost all of it still exists today in various forms like jewelry, coins, bars, electronics, and reserves held by central banks.
  46. Gold is so heavy that one cubic foot of its weighs half a ton. The largest gold nugget found in California (US) weighs 195 pounds. Gold is incredibly dense—one cubic foot of pure gold weighs about 1,206 pounds, making even small volumes remarkably heavy and valuable. In California, the largest gold nugget ever discovered tipped the scales at 195 troy pounds and was unearthed in 1854 at Carson Hill; it was worth $43,000 at the time, but today its value would soar into the millions due to both its mass and historical significance.
  47. The best diamonds are colored blue-white. The phrase “blue-white” diamonds was once used to describe colorless diamonds (graded D, E, or F) that displayed strong blue fluorescence under UV light, giving them a bluish glow that jewelers marketed as superior; however, this fluorescence can sometimes make diamonds look hazy or oily in natural light, which detracts from their clarity. Modern gemology has moved away from the term due to its ambiguity, instead focusing on the 4 Cs—cut, color, clarity, and carat weight—to assess quality, with D-color diamonds regarded as the most desirable among colorless stones. Meanwhile, genuinely blue diamonds, known as Fancy Vivid Blue, owe their color to boron impurities and are among the rarest and most valuable gems, often fetching millions.
  48. Pearls can dissolve in vinegar due to their composition of calcium carbonate, which reacts with the acetic acid in vinegar; this chemical process releases carbon dioxide, creating a fizzing effect and gradually breaking down the pearl over 24 to 36 hours. The myth of Cleopatra dissolving a pearl in vinegar to impress Marc Antony is rooted in historical lore, and while likely dramatized, the science behind it holds up—though it's more of a slow disintegration than an instant melt.
  49. The Henry Graves Supercomplication timepiece, crafted by luxury watchmaker Patek Philippe over eight years and completed in 1933 for prominent American banker Henry Graves Jr., remains one of the most complex and valuable mechanical watches ever made without computer assistance. Featuring 24 intricate complications, it was sold in 1999 to Sheikh Saud Bin Mohammed Al-Thani of Qatar's royal family for $11 million, and after his passing, it was auctioned again on November 11, 2014 in Geneva, Switzerland, fetching a record $24 million. As of 2025, there have been no new public ownership changes or auctions reported, and the watch is currently believed to be in a private collection, occasionally featured in high-profile exhibitions and horological retrospectives.

  57. The Hamilton Watch Company made history in 1957 with the Ventura, the first battery-powered electric watch. Its avant-garde design reflected the innovation inside, and Elvis Presley famously sported one in Blue Hawaii, giving it instant pop culture cred. This breakthrough kicked off a wave of technological progress in horology, paving the way for quartz precision and eventually today’s feature-packed smartwatches. From water clocks of the past to watches powered by body heat, the journey of timekeeping has been as inventive as it is fascinating.
  58. The Elgin National Watch Company and the Hamilton Watch Company pioneered the first electric watch in 1950s. The first quartz watch to enter production was the Seiko 35 SQ Astron, which hit the shelves on 25 December 1969. The first wristwatch was invented by Louis Cartier in 1907.
  59. In 1814, Sir Francis Ronalds of London invented the first electric clock; it was powered with dry piles, a high voltage battery with extremely long life but the disadvantage of its electrical properties varying with the weather. In 1815, Giuseppe Zamboni of Verona invented and showed another electrostatic clock run with dry pile batteries and an oscillating orb. In 1840, Alexander Bain, a Scottish clock and instrument maker was the first to invent and patent a clock powered by electric current.
  60. In 1787, Levi Hutchins of Concord, New Hampshire (US), created what's recognized as the first American alarm clock, though it was a personal device that rang only at 4 AM to wake him for work—it wasn’t adjustable and never intended for public use. It wasn't until 1847 that French inventor Antoine Redier patented the first adjustable mechanical alarm clock, revolutionizing the concept by allowing users to set their own wake-up time. Redier’s innovation marked a significant milestone in timekeeping, paving the way for modern alarm clocks as we know them today.
  61. Casio's G-Shock models have earned a reputation for near-indestructibility, with one famous test demonstrating that the watch kept working perfectly after being dropped from a fourth-story window. This toughness stems from their unique construction, which includes a shock-absorbing floating module encased in protective urethane, a reinforced case that shields internal components, water resistance up to 200 meters, and resilience against vibration, temperature extremes, and electrostatic discharge. G-Shocks have even survived being run over, hammered, and hurled from balconies, making them a trusted choice for those who need their watches to withstand serious punishment.
  62. Apple consistently sets the time to 10:09 in its promotional images of the Apple Watch as a subtle, strategic design choice that pays homage to the traditional 10:10 setting used in analog watch advertising. This slightly earlier time maintains the aesthetically pleasing "smile" created by the positioning of the hands while offering near-perfect symmetry and unobstructed visibility of the Apple logo. The decision also symbolizes Apple's ethos of being ahead of the curve—just a minute ahead of convention—reflecting their attention to detail and forward-thinking brand philosophy.
  63. Setting clocks and watches to 10:10 is a deliberate and time-honored marketing strategy that dates back to the 1930s or 1940s. This position creates a symmetrical, visually pleasing layout that frames the brand logo—typically placed just below the 12 o'clock mark—without obscuring it. It also ensures the hands don’t overlap, allowing their design to be fully appreciated, and gives the watch face a “smiling” appearance, which subtly evokes positive emotions in potential buyers1. While myths abound about historical events tied to 10:10, the real reason is all about aesthetics and psychology.
  64. The global watch industry produces around 1.2 billion watches each year, a testament to how timekeeping permeates daily life. While mechanical watches—known for their intricate craftsmanship—remain popular, especially in luxury segments, they do not account for 77% of the total market by volume. That figure likely reflects consumer preference or market share by value in specific niches, as quartz and digital watches dominate the more affordable and mass-produced categories. So, although mechanical timepieces hold a revered place in horology, quartz watches lead in sheer numbers worldwide.
  65. Switzerland's atomic clock is nothing short of a technological marvel. By measuring the oscillations of atoms—typically cesium or rubidium—it maintains time with astonishing precision. The accuracy is so refined that it wouldn't be off by more than a single second even after 30 million years, which is mind-bending when you think about how much the Earth could change in that time. These clocks form the backbone of global timekeeping systems and even help calibrate GPS and scientific experiments where split-second timing matters.
  66. Rolex revolutionized wristwatch design with two major innovations that shaped modern horology. In 1945, they introduced the Datejust, the first self-winding chronometer wristwatch to display the date on the dial—a practical feature that’s now standard across many timepieces. Then in 1954, they unveiled the GMT-Master, crafted in partnership with Pan Am pilots, which enabled wearers to track two different time zones simultaneously using a 24-hour hand and a rotatable bezel. These iconic developments blended style, precision, and utility, cementing Rolex's status as a pioneer in functional luxury.
  67. The Rolex Submariner, first unveiled in 1954 at the Basel Watch Fair, was designed as a rugged tool for professional divers—not a luxury accessory. Engineered for underwater exploration, it featured exceptional water resistance, legibility in low-light conditions, and a rotating bezel to track dive time. Over the decades, its robust build and timeless design have made it a versatile choice for both men and women, transcending fashion trends and age groups. Though it began as a utilitarian instrument, the Submariner’s reputation for durability and style eventually elevated it to icon status in the luxury watch world.
  68. The first self-winding Rolex wristwatch hit the market in 1931, powered by a groundbreaking internal mechanism known as the Perpetual rotor that harnessed the movement of the wearer's arm to maintain its charge. This innovation set a new benchmark for reliability and convenience in timekeeping. However, the concept wasn't entirely new—British watchmaker John Harwood had already patented a self-winding design in 1923, securing a Swiss patent a year later and debuting his watches through Fortis and Blancpain at the 1926 Basel Fair. Harwood's inventive approach even eliminated the winding crown, replacing it with a rotating bezel to improve resistance to water and dust. His early efforts laid the foundation for Rolex's refinement and global popularization of the automatic wristwatch.
  69. Watchmakers often refrain from claiming their timepieces are 100 percent waterproof because guaranteeing total impermeability is nearly impossible due to the intricate components and variables involved. Instead, they use the term "water-resistant," acknowledging that factors like aging seals, exposure to chemicals, temperature fluctuations, and dynamic water pressure can compromise a watch's integrity over time. Legal standards like ISO 22810 even prohibit the term “waterproof,” reinforcing the idea that no watch can withstand every possible aquatic scenario. Even the most robust dive watches require regular maintenance to preserve their resistance, making it essential for users to understand and respect their watch's limits.
  70. The Patek Philippe Henry Graves Supercomplication Watch is a marvel of horological engineering.

His patented Di-Axial escapement improves efficiency and rivals Swiss mechanisms in innovation and complexity. Together, these artisans elevate China's watchmaking legacy, showcasing its ability to rival Swiss haute horology through precision, creativity, and independent spirit.
    • Tan Zehua, also an AHCI member, is known for crafting his own movements and tools entirely by hand. His watches often feature long power reserves, patent-pending escapements like the Di-Axial, and dials that incorporate traditional Chinese timekeeping elements. His "Work No. 1" movement, for example, includes a massive 16mm balance wheel and a sub-dial for Chinese hours5, while later models showcase advanced finishing techniques and mechanical innovations.
    • Kiu Tai Yu, often called "Mr. Tourbillon", was the first Chinese watchmaker to build a tourbillon wristwatch in 1990 and later became the first Asian member of the prestigious AHCI (Académie Horlogère des Créateurs Indépendants). His creations, such as the Mystery Tourbillon, feature innovative escapement designs and dials inspired by Chinese culture, including celestial maps and dragon motifs1. Each piece is handcrafted and unique, with only about two dozen tourbillons produced over his career.
  88. China's modern watch industry took root in 1955, when four skilled craftsmen in Tianjin successfully built the country's first wristwatch with a lever escapement, marking a pivotal moment in Chinese horology. This prototype, known as the WuXing (Five Stars) watch, was handcrafted using basic tools and laid the foundation for industrial-scale watchmaking. Soon after, the Tianjin Watch Factory was established, later evolving into Tianjin Seagull, which would become one of the world's largest producers of mechanical movements. Around the same time, the Shanghai Watch Factory emerged as another major player, producing high-quality watches and pioneering domestic movement designs. These two factories—often referred to as part of China's "Big Three" along with Beijing—helped transform the nation from a watch-repairing culture into a global manufacturing force.
  89. India's contribution to timekeeping and astronomy is beautifully exemplified by the Jantar Mantar observatories, built in the 18th century by Maharaja Jai Singh II. These monumental structures—located in cities like Jaipur, Delhi, Ujjain, Varanasi, and Mathura—feature massive stone instruments designed to measure solar time, track celestial bodies, and predict astronomical events. The most famous, in Jaipur, houses the world's largest stone sundial, the Vrihat Samrat Yantra, which can measure time with an accuracy of just two seconds. These observatories blend architectural brilliance with scientific precision, showcasing India’s deep-rooted legacy in astronomical innovation.
  90. Japan's use of incense clocks is a fascinating blend of practicality and ritual. While incense clocks originated in China or India, they spread to Japan by the 8th century, if not earlier. These timepieces measured time through the controlled burning of incense sticks or powdered trails, which had calibrated burn rates. In temples, they marked intervals for prayers and ceremonies, while in homes they served both as timekeepers and as sources of fragrance and ambiance. Some clocks even used different scents to signal the passage of time, and in certain traditions—like with geishas—the number of incense sticks burned could determine the length of a visit. Their elegant simplicity and sensory appeal made them a cherished part of Japanese daily and spiritual life.
  91. China's legacy in timekeeping traces back to the Han Dynasty (1st century), where early water clocks used calibrated vessels to measure time through controlled water flow—vital for officials managing schedules and correspondence. This ingenuity reached its peak in the 11th century with Su Song's Astronomical Clock Tower, a towering 30-meter marvel that blended hydrodynamics with astronomical observation. Powered by a water-driven escapement mechanism, the tower featured a celestial globe, a mechanical armillary sphere for tracking planetary motion, and clock jacks that rang bells and displayed time visually. It was a remarkable fusion of science, engineering, and artistry—centuries ahead of its time.
