With a winding crown to the base, this miniature "mystery" clock is an example of Cartier's smallest mechanisms that they ever made. It is more common to come across "mystery" clocks which house two glass prisms inside which are larger but this example is delightfully attractive as being a miniature 1 inch tall version. The idea was invented by Gaston Cusin in 1937 and this is possibly one of the very first of its kind to be made, housing a caliber 402 at just 15mm wide.
