Audemars Piguet Royal Oak Offshore Chronograph 26470
What is the Audemars Piguet Royal Oak Offshore 26470?
The 26470 is the 42 mm Royal Oak Offshore chronograph of its generation: the Offshore's muscled case, rubber clad pushers and crown, and the Mega Tapisserie dial, in a 42 mm case about 14.5 mm thick. The store's listings record the same movement across the reference: calibre 3126/3840, Audemars Piguet's automatic base calibre with a chronograph module, with a power reserve of about 50 hours and water resistance to 100 metres. The reference is worn on a strap with a pin buckle in most configurations, and on a full gold bracelet in one, and that split is the first variant lesson.

Which 26470 variants are there, and how can you tell them apart?
The middle letters of the reference name the case material: ST is stainless steel, OR is 18k rose gold, IO is titanium, per the store's listings. The nicknames the market uses sit on top of that code, and the store's listings carry most of them:
Variant matrix
| Reference | How to tell it apart |
|---|---|
| Brick (reference segment 1000OR) | Rose gold on the full rose gold bracelet, listed with black and grey dials. The bracelet is the name: a solid gold Offshore on its bracelet reads as a brick of gold. |
| Half Brick (segments A002CR and A125CR) | Rose gold on a strap instead of the bracelet, listed with black, gold, and rhodium dials. Same case as the Brick, half the metal. |
| Vampire (A101CR; also listed as 26470SO) | Steel, a dark dialed steel configuration. A second steel listing pairs the Vampire name with Dark Knight in its title. |
| Elephant (A104CR) | Steel, the grey toned configuration. |
| Havana (A099CR) | Steel, the brown toned configuration. |
| Ghost (A006CA) | Titanium with ceramic, the lightest case material in the reference. |
The suffix after the material segment records the strap and dial configuration, so two 26470ST watches can be different variants with different dials. The nickname is a shortcut, not a specification: work from the full reference, then confirm the dial and strap on the watch.
One disclosure this family requires. The store also lists a 26470 built by AET Remould, a sapphire cased conversion produced in a numbered series. It is a customized piece built on the reference, not a factory Audemars Piguet configuration, and it is listed and sold as exactly that. It is not a base example for this guide, and any 26470 with a replaced case or dial deserves the same treatment: disclosed in writing, component by component.
What should you check on any 26470?
- The full reference including the material segment and the suffix, against the case, dial, and strap in hand.
- Bracelet or strap: on the rose gold references, Brick against Half Brick is the single biggest configuration difference in the family, and it is settled by whether the watch is on the gold bracelet or a strap.
- The strap's condition and completeness, since most of this family lives on straps and a worn or swapped strap changes the set.
- The chronograph: start, stop, and reset to zero, on a modular movement where a fault is a service conversation, not a detail.
- Any customization in writing: if a component is not factory, the listing should say which one, as the store's AET Remould listing does.
