Audemars Piguet Selfwinding

Audemars Piguet's Royal Oak Selfwinding 15551ST.ZZ.1356ST.05 is a steel watch with a case measuring 37 mm across and 9.1 mm thick. The dial is blue, finished in the "Grande Tapisserie" pattern, and sits under a sapphire crystal. The watch is set with diamonds. Hours, minutes and centre seconds appear alongside a date display, run by the self-winding Calibre 5900. This movement was introduced alongside the current Royal Oak design in 2022. The watch closes on a steel bracelet fitted with an AP folding clasp, matching the case in finish and weight. Water resistance is rated to 50 metres, enough for daily wear and the occasional splash.
