Audemars Piguet Frosted Gold Selfwinding

Audemars Piguet's Royal Oak Frosted Gold Selfwinding, reference 15550BA.GG.1356BA.01, measures 37 mm in yellow gold with a hammered, frosted finish. The case stands 8.9 mm thick and carries a gold sunburst dial under a sapphire crystal. Inside is the self-winding calibre 5900, which drives central seconds and a date display. The date sits discreetly within the dial layout, keeping the finish as the focus rather than added complication. Its bracelet is yellow gold as well, matching the frosted texture of the case, and closes with an AP folding clasp. Water resistance is rated to 50 metres.
