Audemars Piguet Ref. 26238OR.OO.2000OR.01 — Variants and collector names
Known as: The Beast, Brick, AP Brick Rose Gold
Production phases and changes
- 2021: Generation change: Cal. 3126/3840 (modular, Dubois-Depraz module) → Cal. 4404 (fully integrated in-house flyback). Simultaneously: new case design 26238, revised pusher aesthetics (blue rubber), Interchangeable Strap System.
Crystal variants
- Double Glareproofed Sapphire
In 2021, Audemars Piguet made a cut to the Royal Oak Offshore Chronograph family that you notice the moment you open the case back. The predecessors — the 26400, 26405 and 26470 — ran on the Cal. 3126/3840, a solid base movement with a bolted-on Dubois-Depraz chronograph module, the same setup half the watch industry uses at this price point. With the Ref. 26238OR.OO.2000OR.01 comes the Cal. 4404: a fully integrated in-house flyback chronograph movement, with no module stacked on top anymore. That's the real reason collectors treat this reference as a turning point rather than a routine update.
## Where the Name Brick Comes From
In the trade, the 26238OR circulates under three names at once: The Beast, for its 43mm rose gold case; Brick, for the massive, angular bracelet links; and AP Brick Rose Gold, a combination of both used in insider circles. All three names now come up in buying conversations without customers ever mentioning the reference number — a clear sign of how firmly the nickname has taken hold on the secondary market.
## What Actually Changed on the Case
Alongside the caliber switch, AP also refreshed the look in 2021: reworked pushers with a blue rubber insert instead of the previous metal version, plus the Interchangeable Strap System, which lets you swap the bracelet without tools. That matters twice over when it comes to valuation — in my experience, a Cal. 4404 with a full box-and-papers set and a working quick-release system sits noticeably above an otherwise identical watch missing its accessories.
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.

What matters at this price point
At $129,093 we are no longer talking about an everyday watch but a collector's piece. Every detail drives the price: an original dial can be worth five figures more than a service dial, missing papers noticeably depress the value, and an over-polished bezel is effectively lost money. Anyone buying in this range should take their time and, when in doubt, take a second look.

The price of the Royal Oak Offshore Chronograph has risen by +13.4% over the past four months. Anyone selling now hits a good window. If you want to buy: no need to wait — the market is currently more hot than cold, and a clear end to the trend is not in sight.
