The Audemars Piguet Royal Oak Offshore ref. 25940, better known as the Rubberclad, is a 42 mm automatic chronograph with a vulcanized rubber overlay on the bezel. Replica versions fall into three rough tiers: cheap 21,600 vph automatic or quartz builds, mid-tier builds using a decorated 7750 base, and high-end builds from factories such as JF and APSF that copy the case profile and dial texture closely. The best replicas capture the silhouette and the Mega Tapisserie dial. None match the hand finishing, the rubber compound, or the chronograph feel of the genuine calibre.
What the Genuine 25940 Specifies
- 42 mm case in stainless steel or rose gold, roughly 14 mm thick
- Rubber-clad bezel held by eight exposed hex screws
- AP Calibre 2326/2840 automatic chronograph, built on a Jaeger-LeCoultre 889 base
- Mega Tapisserie dial with three subdials and a date window at 3 o'clock
- Sapphire crystal front and back, 100 m water resistance
- Production ran from roughly 2002 into the early 2010s, so the reference is long discontinued
Where Replica Builds Diverge
Case and Bezel
The genuine bezel is a steel core with a molded rubber skin, and the rubber sits flush with the screw heads. Replicas often use a rubber sticker over a metal bezel, which lifts at the edges within months. Check the gap between rubber and case, and press a fingernail against the edge. Soft adhesive means a low-tier build.
Dial
Mega Tapisserie squares should be raised, cut cleanly, and evenly spaced. On replicas the squares are frequently shallow, rounded at the corners, or misaligned with the printed minute track. Subdial rings on cheap builds are flat stamped discs rather than recessed and snailed.
Movement
A 7750-based replica runs at 28,800 vph and hacks, but the chronograph starts with a stiff pusher and the seconds hand stutters. Genuine 2326/2840 architecture is thin and smooth. Decorative plates and fake jewel settings are a common cover-up, so look at the balance wheel location rather than the engraving.
Inspection Checklist
- Measure the case across the bezel with calipers and confirm 42 mm.
- Examine the dial with a 10x loupe for square depth and spacing.
- Press the bezel rubber at the 12 and 6 positions to test adhesion.
- Start and stop the chronograph five times and listen for a consistent pusher click.
- Set the watch on a timegrapher and record the rate in six positions.
- Advance the hands past midnight and confirm the date changes within five minutes.
- Inspect the caseback engraving and confirm the eight screws sit in matching slots.
Straps and Fit
The 25940 uses a thick rubber or leather strap with a tang buckle. Replica straps are usually the weakest part of the package: harder rubber, uneven stitching, and a buckle without the correct bevel. Budget for a replacement strap from a third-party maker if you plan to wear the watch daily.
Price Expectations
Genuine 25940 examples trade in the low five figures, with rose gold versions higher. Replica pricing runs from under $100 for generic builds to several hundred dollars for factory-tier pieces. Anything above that range for a replica is marketing, not materials.
Legal Note
Replica watches infringe trademarks and cannot be sold as genuine. In the United States, importing counterfeits is prohibited, and selling one as an original is fraud. Treat any replica as a novelty item and never present it as a real Audemars Piguet.
