Coin watch

[1] A coin watch is typically made by slicing a coin into two disks, one thinner than the other;[1] or by removing one face of a coin.

A watch mechanism is then embedded into the thicker part, and the two faces joined by a concealed hinge and catch.

[1] When closed, the watch is hidden and the coin looks like any other.

[1] Noted makers of coin watches include Cartier[1][2] and Corum.
