Model: Twenty Dollar Coin Watch Reference: 900B Case Material: Yellow Gold Bracelet Material: Leather Strap Year: 1970's Movement: Manual Caliber: 9P Case N°: 1904 Movement N°: 860285 Dimensions: 35 mm Signed: Dial, Movement and Case The history of coin watches is an intriguing chapter in horology, with several manufacturers embracing the coin-shaped timepiece during the 1920s. These watches are distinguished by cases crafted entirely from two coins, a technique perfected by the head watchmaker of the European Watch and Clock Company in Paris Joseph Vergely. Among the leaders in this niche, Piaget has stood out as a master in the art of ultra-thin watchmaking, a legacy the brand continues to uphold. By the 1960s, Piaget was already well-known for its technical prowess, with their coin watches being celebrated in publications like the 1961 article, “Reception by Piaget in Mexico City,” where they were hailed as the “universally known Piaget coin watches.” Initially produced as pocket or desk watches, Piaget later ventured into creating wristwatches in the form of coins, such as the exceptional example presented here. Encased in a 35 mm yellow-gold coin-edged case, the watch features a hinged front opening crafted from a $20 coin, with a matching $20 coin caseback. The front is opened using a square pusher, revealing a stunning sunburst “salmon” dial with delicate pencil hands. Inside, a manually wound movement powers the timepiece, showcasing Piaget’s expertise in creating both beauty and precision. Exceptionally well-preserved and truly eye-catching, this rare coin watch by Piaget exemplifies the brand’s out-of-the-box thinking and innovative spirit, making it a prized piece for collectors and a testament to Piaget’s enduring commitment to excellence in horology.
