The Royal Oak Chronograph 25940 is the reference that proved the octagonal Royal Oak case could carry a full chronograph layout without losing its identity. It remains one of the most requested silhouettes among replica buyers, and it is also one of the easiest to get wrong. This guide walks through what a well-built fake Audemars Piguet Royal Oak Chronograph 25940 should look like before you commit.
Key Features
- Octagonal case with eight exposed hexagonal bezel screws set in the correct alignment

- Three-register chronograph dial with a date window positioned at 3 o'clock
- Scratch-resistant sapphire crystal with an anti-reflective coating
- Screw-down crown and screw-down chronograph pushers
- Automatic chronograph movement with a power reserve of roughly 40 hours
- Available in stainless steel, two-tone, and a range of dial colors
- Removable links so the bracelet can be sized from about a 6.25-inch wrist upward
Materials and Specifications
Case and bracelet are normally 316L stainless steel, with the sharp alternating brushed and polished bevels that define the Royal Oak profile. Check that the top bezel plane is brushed while the bevels are mirror-polished, that the bracelet links flex without rattling, and that the caseback sits flush. Dials should have applied baton markers, printed or applied subdial rings that sit level, and hands that align cleanly at twelve. Genuine-spec dimensions put the case around 42 mm across with a screw-down crown, so a replica that bulges noticeably past that figure will wear differently on the wrist. Water resistance is usually rated for splashes and hand washing only, not swimming.
Shipping and Returns
Orders are typically packed discreetly with no external branding and dispatched with a tracking number within one to two business days. Most sellers offer a short inspection window after delivery, so open the parcel promptly, confirm the movement runs and the chronograph resets to zero, and report any transit damage right away. Defective pieces are generally replaced or refunded; sizing mistakes on the bracelet are usually resolved with spare links.
What movement should I expect in a 25940 replica?
Most current examples run an automatic chronograph movement built around a modular layout similar to the original's Frederic Piguet-based caliber. Ask whether it is a 7750-derived or a Seagull-based unit, since the 7750-derived version generally holds better time.
How close is the case finishing to the genuine reference?
Good examples reproduce the alternating brushed and polished surfaces closely. The quickest tell is the bezel screws: their slots should sit in a neat, consistent line, and the screw heads should be slightly proud of the bezel.
Will the bracelet fit a smaller wrist?
Yes in most cases, provided the listing includes removable links. Ask the seller for the minimum wrist size before ordering if you measure under 6.5 inches.
