Royal Oak Offshore Rubber Clad Chronograph in Steel with Rubber Bezel 42mm

The Audemars Piguet Royal Oak Offshore Rubber Clad Chronograph Ref. 25940SK.O.0002CA.02 represents what many collectors consider the golden era of the Offshore collection. Our vintage specialists have tracked the market trajectory of these early rubber-integrated models with particular interest, noting their growing significance among enthusiasts who appreciate their historical importance in the evolution of luxury sports chronographs. Released circa 2003, these models pioneered the integration of rubber directly into case construction rather than merely as a strap material—an innovation that influenced countless luxury sports watches that followed.

Examining the technical specifications reveals the groundbreaking approach of this reference: The 42mm stainless steel case features rubber-clad architecture with rubber bezel, crown guards, and pushpiece surrounds, creating a distinctive aesthetic while enhancing shock resistance. The chronograph calibre inside delivers precision timing with three registers, operating at 28,800 vibrations per hour with approximately 40 hours of power reserve. The silver dial with Arabic numerals offers exceptional legibility compared to later Offshore generations, with the chronograph counters positioned at 3, 6, and 9 o'clock and the date window at 3 o'clock. Water resistance of A100m ensures practical capability, matching its sporting design.

Master Luxury offers this historically significant timepiece in excellent condition with original box and papers dated September 2003. Our authentication process has verified that all case numbers and movement specifications match factory records, while our inspection confirms excellent mechanical condition. The tiny mark on the bezel mentioned in the condition notes requires a loupe to identify—precisely the kind of honest wear that distinguishes properly preserved examples from those that have been overly refinished. This increasingly sought-after piece from AP's experimental period represents an important chapter in the evolution of the Royal Oak Offshore collection.
