X years
Introduced in 2023 as the successor to the 50th-anniversary model, the 15510ST marks a subtle yet assertive evolution. The 41mm octagonal case in brushed-satin steel, punctuated by its eight visible hexagonal screws, remains one of the most recognizable signatures in contemporary watchmaking. The gray Grande Tapisserie guilloché dial plays with light with every movement of the wrist.
Beneath the transparent sapphire case back, the automatic manufacture caliber AP 4302 comes to life, visible in all its finishing. It ensures hours, minutes, seconds, and date — the essentials, meticulously mastered.
Carefully worn, this 15510ST is in the excellent condition expected of a piece maintained by an attentive enthusiast. It is offered with its box and its original full set of papers — a complete package that preserves all its heritage value.
Before joining our showcases, each watch passes through the hands of our experts — authentication, movement verification, comprehensive inspection. This Royal Oak is guaranteed for 1 year by L'Écrin Genève.
