The 15510ST is the current 41 mm steel Royal Oak Selfwinding, introduced in 2022, the year the Royal Oak turned fifty. It succeeds the 15500ST and holds on to Gérald Genta's 1972 design: the octagonal bezel with eight hexagonal screws, the bracelet integrated into the case with tapering links, and the Grande Tapisserie dial.
Like its predecessor, the 15510ST has the in-house calibre 4302, with a power reserve of about 70 hours and a 22 ct gold rotor visible through the display back. The first examples carried a rotor commemorating the Royal Oak's fiftieth anniversary. The watch has a date at three o'clock and is water-resistant to 50 metres.
A Royal Oak on a steel bracelet sits close to the wrist; because the bracelet is integrated into the case, no other strap is intended. On a pre-owned example we look at the finishing of case and bracelet, at the folding clasp and at the set. With a recent reference such as this one, buyers usually expect box, certificate and guarantee card, and we state exactly what is present.
