The Audemars Piguet Royal Oak ref. 15550ST is the perfect balance of proportions and presence. At 37mm, it keeps the iconic Royal Oak details, including the octagonal bezel with exposed screws, the integrated bracelet, and of course the blue “Grande Tapisserie” dial, but in a size that works effortlessly for both men and women. The brushed steel case and bracelet play beautifully with the dial, giving the watch its unmistakable AP character. This 2025 example is pre-owned and comes complete with box and papers.
Inside is the self-winding Calibre 5900, a slim automatic movement visible through the sapphire caseback. For anyone looking for the versatility of the Royal Oak in a more wearable size, the 37mm blue dial is a modern classic that doesn’t stay on the market for long.
