Audemars Piguet 15550ST.OO.1356ST.03 Royal Oak Selfwinding 50Th Anniversary 37mm Stainless Steel

The Audemars Piguet 15550ST.OO.1356ST.03 is a reminder that true icons don’t need reinvention. They need proportion, restraint, and confidence. This 37mm Royal Oak Selfwinding was introduced to mark the 50th anniversary of Gérald Genta’s legendary design, and it feels exactly like a watch that knows where it comes from.

The stainless steel case sits beautifully on the wrist. Not too sporty, not too dressy. The famous octagonal bezel with eight white gold screws is crisp and architectural, while the alternating brushed and polished finishes show Audemars Piguet’s obsession with detail. At 37mm, this model feels modern yet timeless ideal for collectors who appreciate balance over bulk.

Dial, Movement, and Wearability

The “Grande Tapisserie” dial adds texture without clutter. Applied white gold hour markers and hands offer excellent legibility, helped by subtle lume that stays tasteful. Turn the watch over and the sapphire caseback reveals the anniversary rotor, a quiet nod to the Royal Oak’s 50-year journey.

Powering the watch is the in-house Calibre 5900 automatic movement. It beats at 4Hz and offers a strong power reserve, making it practical for daily use. This isn’t a watch you keep locked away. It’s built to be worn.

The integrated stainless steel bracelet is a highlight on its own. Flexible, ergonomic, and beautifully finished, it melts onto the wrist and reinforces why the Royal Oak bracelet is still considered one of the best in the industry.
