Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Selfwinding Chronograph 26240BA.OO.1320BA.01 is a chronograph in 18-carat yellow gold, measuring 41 mm across and 6.8 mm thick. The gold dial is stripped of its usual counters and indexes, leaving a plain, uncluttered face for the case. A sapphire crystal covers the dial. Inside is the self-winding calibre 4409, which drives a flyback chronograph with small seconds and displays hours and minutes. This reference is a limited edition, produced in collaboration with designer Matthew Williams. The bracelet is 18-carat yellow gold, fitted with an AP folding clasp that closes securely over the wrist. Water resistance on this Royal Oak is rated to 50 metres.
