Serial numbers
- I-Serie – I-Serie (2014–2015) — AP uses letter-series prefixes; I-series approx. 2013–2015. No official AP tables available, data from collector sources.
- J-Serie – J-Serie (2016–2018) — AP J-series approx. 2016–2018. No official AP tables available.

Hardly anyone knows reference 26401RO.OO.A002CA.02 by its AP number — in the trade it goes by "Rose Gold Beast," or simply "Offshore Rose Gold." A 44mm case, black Méga Tapisserie dial, rose gold bezel in ceramic. That exact combination makes this reference one of the most attainable entry points into the Offshore chronograph world with a precious-metal case.
## The Dial Change Almost Nobody Notices
Back in 2016, Marc Gebauer was still listing the .01 version; today AP's own website shows only the .02.A, complete with an interchangeable strap set. The shift wasn't a redesign in the classic sense — the black Méga Tapisserie pattern stayed the same, but the dial itself was reworked. No source pins down the exact transition point between .01 and .02 with any precision, which is exactly why it keeps coming up as a question during authentication requests.
## The 500 Pieces Shaking Up the Market
In 2020, the limited edition reference 26401RO.OO.A087CA.01 arrived and has been pushing secondary-market prices well above the .01/.02 series ever since. 500 pieces, brown ceramic bezel, desert camouflage strap, sold exclusively through AP boutiques. It launched alongside two steel variants in blue and khaki, also limited, at 400 pieces each. Rose gold remained the only precious-metal execution across the entire camouflage lineup.
## Why the Distinction Matters When Buying
Anyone offered a 26401RO should check the dial code first, then the bezel material. Between a regular .02 and the limited .A087CA.01 lies a world of difference in market value — and that's precisely where a clean authenticity check needs to happen before any price talk begins.
Brand profile: Audemars Piguet
AP Royal Oak is one of the most coveted and most counterfeited luxury watches. The distinctive octagonal bezel with 8 screws and the tapisserie dial are the central inspection points.
- Date disc: genuine caliber 3120/5120 flips the date INSTANTLY at midnight (a snapping jump) — clones creep from 23:00 to 01:00
- Thickness: Royal Oak Jumbo 15202 is exactly 8.1 mm thick — clones measure 8.4–8.8 mm (movement sits too tall) — calipers reveal it immediately
- Tapisserie dial: under 10× magnification the pyramid edges must be sharp and geometrically precise — fakes show soft, pressed, or laser-etched surfaces
- Bezel screws: 8 hexagonal screws with mirror polishing and exact alignment — fakes: flatter, duller, asymmetric
Serial number format: AP serial numbers: 6–7-digit number engraved between the lugs at 9 o'clock. Reference number engraved separately on the opposite side. Very small — barely legible without a loupe.

Market situation and price range
At $34,514 the Royal Oak Offshore Chronograph sits in a segment where first owners sell regularly — clean pieces with box and papers are not uncommon.

Watch out for swings: This reference has an above-average volatility of 173.4 percent. In concrete terms: the price can move by several hundred euros within a few weeks. Check the current value before buying or selling — old listings or auction results from two months ago are of little help.
