Here we have one of the rarest (maybe 1/1) and the most interesting piece from Audemars Piguet we have ever seen. 

The 18k white gold case measuring 33,5 mm in diameter is in sharp condition and refined with a very unique 18k white gold 'Bismark' finished bracelet. The icing on the cake is the rare deep matt grey dial in flawless condition.

It fittet with the caliber 2120 which is one of the most famous in the watch industry. Jointly developed by LeCoutre & Cie, Audemars Piguet and Vacheron Constantin, it remained for several decades the world's thinnest mechanical movement with automatic winding and central rotor. It is notably distinguished by its 21-carat oscillating weight on ruby rollers, which gravitates around a circular track.
