The Audemars Piguet calibre 3120 is now considered one of the greatest automatic movements ever made. Fitted on several models across the Royal Oak collection— including the discontinued ref. 15300, the recently launched ref. 15400 and the Royal Oak Offshore Diver amongst others—, calibre 3120 is a work of art and truly one of the nicest movements you can find out there. Not to mention that is also extremely accurate.

This beautiful and precise calibre, is fully decorated with Côtes de Genève on all bridges and comes with a stunning bi-directional 22k gold rotor. The rotor features the coats of arms for the Audemars and Piguet families, all done with immaculate attention to detail.
