The Audemars Piguet Royal Oak Offshore Chronograph 43mm (Ref. 26420SO.OO.A002CA.01) combines precision and style in a robust design. Its 43mm stainless steel case features a black ceramic bezel, housing a black "Méga Tapisserie" dial with white gold applied hour markers and luminescent hands. Powered by the self-winding Calibre 4401 movement, it offers a 70-hour power reserve. The watch includes a black rubber strap with a stainless steel pin buckle and an interchangeable system, along with a brown calfskin strap. Water-resistant up to 100 meters, this timepiece is a testament to Audemars Piguet's craftsmanship.
