The coin watch is made by slicing a coin in half, with one half thinner than the other. In some designs, the thinner portion serves as the dial, while the thicker part houses the watch movement. Alternatively, two coins may be used to create the watch, serving merely as a container for a smaller watch inside.
The present example from Piaget is an attractive illustration of a coin watch and is preserved in good overall condition. Inside the case lies an ultra-thin Piaget movement, powered by their renowned caliber 9P. The hallmarks on the caseback indicate that the case was exported from France and imported to Switzerland for movement assembly, which is reflected in the “Swiss” designation on the dial.
Notably, this watch is accompanied by an additional gold ten-dollar coin, serving as a matching pendant. This piece represents a unique opportunity for a collector to own an intriguing timepiece that is sure to be a conversation starter at social gatherings.
