Versions of this ingenious watch were introduced in the 1930s and set a precedent for similar time pieces by master watch makers, particularly so for Corum as the coin watch became a signature marque for the brand. The masterful concealment of a watch in a hollowed-out 90% gold American U.S. twenty dollar coin is a display of inventive horological craftsmanship at its creative and whimsical best.
