Coin watches offer a captivating glimpse into the history of horology. These ultra-slim timepieces were crafted from legal tender, requiring two coins to be split to form their outer case, while a remarkably small watch remained completely concealed within a separate, hinged case. Audemars Piguet is one of many Swiss brands that produced these exquisite creations, with production continuing into the early 1990s. Typically, historic United States $20 coins were used for watches intended for the American market.

Audemars Piguet developed a fine selection of rare coin watches, with the present model featuring a skeletonized movement being their most prestigious. The 1897 Liberty Head coin showcases a bas-relief depiction of “Lady Liberty” on the front cover, while the reverse displays the Great Seal of the United States along with the inscription “United States of America Twenty Dollars”. To open the watch, one must locate the nearly hidden push button on the milled edge of the coin. The concealed case houses a spectacular, skeletonized, and hand-engraved movement with 14K gold bridges. This inner case is hinged and lifts from within the coin to reveal the time.
