Audemars Piguet Ref. 26170OR.OO.1000OR.01 — Variants and collector names
Known as: The Brick, AP Brick, Offshore Brick, Half Brick, Rose Gold Brick
Crystal variants
- Sapphire Crystal
44 millimeters of solid 18-karat rose gold, on both sides of the wrist. The 26170OR.OO.1000OR.01 wears its case, bezel, and bracelet in the same material — a choice that has earned it five nicknames in the collector market: The Brick, AP Brick, Offshore Brick, Half Brick, Rose Gold Brick. Audemars Piguet's Royal Oak Offshore line, the loudest design statement out of Le Brassus since 1993, feels even more compact and substantial in its all-gold configuration — almost sculptural. Anyone who holds this watch understands immediately where the name comes from.
## What the Market Pays for This Reference
Uncompromising rose gold has become a rare sight on the new-watch market. New Offshore chronographs today roll off the line predominantly in steel or titanium, and the 26170OR appears in AP's catalogs only sporadically. On the secondary market, the consequences are clear: examples in good condition regularly achieve between $80,010 and $108,585 while complete sets with box and papers have recently been closer to the $114,300 mark. That represents a premium of roughly 35 to 45 percent over the historical retail price.
## What to Look for When Buying
The 26170OR's characteristic Tapisserie dial cannot tolerate polishing — and rose gold cases attract polishing attempts like no other material. Scratch marks on the eight case flanks or a blunted octagonal bezel relief translate directly into a discount at resale, often running into four figures. Cross-referencing the serial number with AP's production records and checking the three-row integrated bracelet's folding clasp for even deployment pressure will keep any unwelcome surprises out of the purchase equation.
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 drives the price here
At $66,702 the watch sells well if the condition is right. A market rule of thumb: a complete set with box, papers and warranty card brings 10 to 15 percent more than the bare watch. Buying without papers can pay off, but you take the same discount again later when you resell.
Watch out for swings: This reference has an above-average volatility of 25.9 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.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Audemars Piguet Royal Oak Offshore Chronograph reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Royal Oak Offshore Chronograph.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
