Audemars Piguet's new Royal Oak Automatic 15500ST
Audemars Piguet's classic 3-hand watch appears in a new design. The new Royal Oak automatic 15500ST only differs from its predecessor model, the reference 15400ST, in small details. The case height has increased to 10.4 mm. Audemars Piguet has installed the in-house caliber 4302 in this model. This can be admired again through the anti-reflective sapphire crystal back. With this caliber, the power reserve of the 15500ST has increased to 70 hours.

Changes are also noticeable on the dial. The applied indices of the Royal Oak Automatic 15500ST are now wider, but are also a bit shorter. Together with the Royal Oak hands, they were made of white gold. The date display has also been moved more towards the case, i.e. further away from the center of the watch. Furthermore, the Royal Oak automatic was provided with the Grand Tapisserie motif, which is available either in black under the reference 15500ST.OO.1220ST.03 or in slate gray with the reference 15500ST.OO.1220ST.02.
Not everything is new
The 41 mm wide case of the Audemars Piguet Royal Oak Automatic 15500ST was again made of stainless steel. The bracelet is also made of stainless steel and closes with a folding clasp. With its screw-down crown, the Royal Oak automatic is waterproof up to 5 bar.
