The Royal Oak 15500ST is a modern classic with an iconic design. The 41 mm stainless steel case, the octagonal bezel with visible screws, and the integrated bracelet are entirely in the tradition of Gérald Genta's legendary design. The striking black "Grande Tapisserie" dial gives the watch depth and character. Inside, the in-house automatic caliber 4302 with a 70-hour power reserve works – robust, precise, and of high quality. A sporty yet elegant luxury watch with instant recognition, perfect for any occasion.
