The Audemars Piguet Royal Oak Offshore Chronograph Ref. 26400IO.OO.A004CA.01.A is a bold and contemporary interpretation of the brand’s iconic sports chronograph. Crafted in brushed titanium with its signature black ceramic bezel, this model perfectly blends modern materials with the robust elegance that defines the Offshore collection.
The 44 mm case offers a commanding presence on the wrist, while maintaining comfort through its curved design and ceramic pushers. The grey “Méga Tapisserie” dial features contrasting black chronograph sub-dials for enhanced legibility and visual depth.
At its heart beats the Audemars Piguet Calibre 3126/3840, a self-winding movement developed in-house, operating at 21,600 vph with a power reserve of approximately 50 hours. The titanium caseback, engraved with “Royal Oak Offshore,” features a sapphire crystal window showcasing the meticulous finishing of the movement.
This model comes fitted with a grey rubber strap with titanium pin buckle, combining durability and comfort.
The watch, manufactured in 2018, is presented in excellent condition, complete with its original Audemars Piguet box and official documentation.
