The Audemars Piguet Royal Oak Offshore reference 26238BA.OO.2000BA.01 is a highly exclusive luxury chronograph created in collaboration with designer Matthew Williams and his brand 1017 ALYX 9SM. This 42mm timepiece is crafted entirely from 18-carat yellow gold, including the case, fixed octagonal bezel, and integrated bracelet with an AP folding clasp. The design is characterized by a minimalist, fashion-forward aesthetic, featuring a champagne-toned dial with a vertical satin-brushed finish. Notably, the dial removes traditional hour markers and sub-dial scales in favor of a sleek, uncluttered look, leaving only the “AP” logo at 12 o’clock and the “1017 ALYX 9SM” branding at 6 o’clock.
At the heart of this limited edition is the in-house Calibre 4404, a self-winding integrated flyback chronograph movement. It operates at a frequency of 4Hz and provides a substantial 70-hour power reserve. The movement includes a column wheel and vertical clutch system, ensuring precise operation of the chronograph functions, which are displayed via a 12, 9, 6 sub-dial configuration. Additional complications include a date aperture at the 3 o’clock position and a flyback function that allows the chronograph to be reset and restarted with a single press of the pusher. The watch is also engineered for durability, featuring a scratch-resistant sapphire crystal and water resistance up to 100 meters.
General reviews of this collaboration emphasize its role as a bridge between haute horology and avant-garde fashion. Critics and enthusiasts alike highlight the bold choice to remove functional markings from a chronograph dial, transforming a traditionally technical tool watch into a wearable work of art. While the 15.3mm case thickness and 42mm diameter maintain the “Beast” legacy of the Offshore collection, the monochromatic yellow gold execution is praised for its cohesive and opulent presence. With only 76 pieces in existence, the 26238BA is regarded as a rare masterpiece for discerning collectors who value exclusivity and cutting-edge design over traditional legibility.
