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 coins, featuring a distinctive cabriolet-style design with a hinged cover that elegantly protects the dial. The present timepiece is housed in an American $20 gold coin, with the main case hinged at the bottom, revealing a champagne dial with sleek Roman numerals. Lifting the inner case reveals an S. Kocher signature, the founder of Eska in 1918. Supposedly, the name ESKA is a phonetic abbreviation of its founder, Silvan Kocher (“S”ilvan “K”ocher); “ES””KA”. A timepiece of ingenuity and charm, this Eska watch epitomizes the intersection of Swiss precision and mechanical creativity. The deep hallmarks, impeccable finishing, and well-preserved condition underscore the quality of this piece. A timepiece that delights both the connoisseur and the aesthete, this Eska exemplifies the kind of horological artistry that makes collectors fall in love with the brand.
