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.

To the left of the AP engraving on the rotor, we find the Audemars family coat of arms featuring a bird, three stars and a donjon with a flag.   

To the right of the AP engraving on the rotor, we find the Piguet family coat of arms featuring a horse holding a sword and three stars. As you can see in the pictures, every detail from the horse's muzzle to the mane and even the tail have been impeccably executed by the horologists at Audemars Piguet.

This hacking automatic movement features hours, minutes, center seconds and date aperture. The thickness with module is 4.26mm and a total diameter of 26.6mm. The calibre has 40 jewels, a power-reserve of up to 60-hours and 280 parts.  To be quite honest, we can spend another whole day taking more macro pictures of this calibre just for you. Enjoy!
