Royal Oak Offshore Chronograph

Audemars Piguet Royal Oak Offshore Chronograph

The Audemars Piguet Royal Oak Offshore Chronograph Ref. 25940OK.OO.D002CA.01 is one of the most recognizable “Rubberclad” variants within the Royal Oak Offshore family. Introduced in the mid-2000s, it combines the bold architecture of the Offshore with the warmth of 18K rose gold and the rugged look of vulcanized rubber accents.

The watch features a 42 mm 18K rose gold case with a distinctive black rubber-clad bezel and pushers, secured by eight hexagonal titanium screws—a defining element of the Royal Oak design. The grey “Méga Tapisserie” dialenhances the sporty aesthetic with oversized Arabic numerals filled with luminescent material and contrasting chronograph counters.

The dial layout includes:

• Small seconds at 12 o’clock

• 30-minute chronograph counter at 9 o’clock

• Date window at 3 o’clock with magnifier

• Central chronograph seconds hand

The robust case architecture integrates screw-locked crown guards, a scratch-resistant sapphire crystal, and a solid caseback, ensuring 100 meters (10 ATM) of water resistance.

Inside operates the Audemars Piguet Calibre 2326/2840, an automatic chronograph movement built around the AP 2326 base with a Dubois-Dépraz chronograph module. The movement runs at 28,800 vibrations per hour (4 Hz) with 50 jewels, delivering hours, minutes, small seconds, date, and chronograph functions, along with a power reserve of approximately 38–40 hours.

The watch is paired with a black rubber strap secured by a rose gold folding clasp, completing the model’s aggressive yet luxurious Offshore character.
