Designed by the legendary Gérald Genta, the Royal Oak is probably one of the top three most influential watches in watchmaking history. To present it as a legendary product that changed the watchmaking industry is no exaggeration, and only those who refuse to acknowledge the Royal Oak's historical importance categorize it as a "fad" and "overpriced watch". Reference 15450ST is the admirably successful Royal Oak in 37 mm. Thanks to its slimmer, more elegant shape and dial design, the 15450ST 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. Unlike its most recent version, reference 15550ST, the 15450ST features the "Automatic" sign at 6 o'clock, filling out the dial a little and adding symmetry to it. 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 2018, is in mint condition, with its case, bracelet and dial all spotless since the piece has never been worn. Note that there is a slight mark at 6 o'clock on the bezel, the latter having surely appeared during transport or handling. This is normal for a 5-year-old timepiece. For collectors, the 15450ST is the perfect 37mm Royal Oak, embodying the brand's rich heritage and visionary spirit.
