Audemars Piguet 18k Blue Diamond 1970s

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 32,5 mm in diameter is in sharp condition and refined with a very unique 18k white gold beautifully finished bracelet. The icing on the cake is the rare deep blue sunburst dial with 11 diamond hour markers in flawless condition.

Inside we find the ultra thin caliber 2121. It is notably distinguished by its 21-carat oscillating weight on ruby rollers, which gravitates around a circular track.
