Designed by the legendary Gérald Genta, the Royal Oak is probably one of the three most influential watches in watchmaking history. To present it as a legendary product that changed the watchmaking industry is no exaggeration.

The reference 15550ST is the admirably successful Royal Oak in 37 mm. Thanks to its slimmer, more elegant shape and dial design, the 15550ST wears extremely well on a daily basis, being less massive and glaring on the wrist. The 37mm version has always been a good choice for people with slimmer wrists, who don't want to lose the very essence of Royal Oak, which is elegance mixed with sportiness and luxury. The blue dial contrasts perfectly with the steel case, which is very clear thanks to the brushed grain used, highlighting Audemars Piguet's unrivaled expertise and the boldness with which they work their historic product to perfection. This configuration remains the absolute classic for a Royal Oak, and is a must-have for any collector worthy of the name.

This specific piece, sold in 2025, is in new condition, with its case, bracelet and dial all spotless since the piece has never been worn. For collectors, the 15550ST is the perfect 37mm Royal Oak, embodying the brand's rich heritage and visionary spirit.
