The Audemars Piguet Royal Oak Offshore Selfwinding Chronograph reference 26420CE.OO.A063VE.01 is a 43mm luxury sports watch featuring a multi-material case construction. The case middle is crafted from black ceramic, while the octagonal bezel, screw-locked crown, and chronograph pushers are made from green ceramic. These ceramic components are complemented by titanium elements, including the pusher guards, caseback frame, and bracelet studs. The watch is protected by glareproofed sapphire crystals on both the front and the exhibition caseback, ensuring a water resistance of 100 meters. Its dark green dial features the collection’s signature Mega Tapisserie pattern, contrasted by black snailed sub-dials at the 3, 6, and 9 o’clock positions and a black inner bezel with a tachymeter scale.
The timepiece is powered by the in-house Calibre 4401, an integrated selfwinding movement that incorporates a column wheel and a vertical clutch system to ensure smooth chronograph operation. This movement provides a power reserve of approximately 70 hours and features a flyback complication, which allows the wearer to reset and restart the chronograph with a single press of the button. Additional functions include a date display located between 4 and 5 o’clock, small seconds, and 30-minute and 12-hour counters. The watch is equipped with an interchangeable strap system and typically comes with a dark green textured calfskin leather strap and an additional black rubber strap, both featuring a titanium pin buckle.
General reviews of the 26420CE often emphasize its evolved ergonomics, noting that the 43mm case geometry and thinner profile offer improved wearability compared to previous 44mm Offshore models. Collectors frequently praise the striking three-tone aesthetic created by the combination of black and green ceramic with titanium, describing it as a bold yet sophisticated use of high-tech materials. The finishing of the ceramic components, which involves meticulous satin-brushing and polished chamfers similar to metalwork, is highlighted as a testament to the brand’s craftsmanship. While its substantial size remains a point of discussion, the lightweight nature of the ceramic and titanium construction is often cited as a significant benefit for daily comfort.
