Which 26331 variants are there, and how can you tell them apart?
The metal code after 26331 does the first sort, and the closing digits name the dial:
Variant matrix
| Reference | How to tell it apart |
|---|---|
| 26331ST.OO.1220ST.03 | Stainless steel, the Panda dial, on the steel bracelet. |
| 26331OR.OO.1220OR.01 | Rose gold, blue dial, on the rose gold bracelet. |
| 26331OR.OO.D315CR.01 | Rose gold, blue dial, on a leather strap. The D315CR segment in place of 1220OR is the tell that this example wears a strap, not the bracelet. |
| 26331BA.OO.1220BA.01 | Yellow gold, blue dial, on the yellow gold bracelet. |
| 26331BA.OO.1220BA.02 | Yellow gold, green dial, on the yellow gold bracelet. |
ST, OR, and BA are steel, rose gold, and yellow gold. Two rose gold watches with the same blue dial are separated entirely by the middle segment of the reference: bracelet or strap is a reference-level fact on this model, not an accessory choice, so a 26331 offered without its reference leaves the most important question unanswered.
What should you check on any 26331?
On the bracelet versions, count the links: one of the store's sets states it is supplied fully linked with all 21 links, and a short bracelet is a cost and a sourcing problem on an integrated design that takes no generic links. Papers differ across the family in a way worth checking before anything else: most of the store's sets carry the warranty card, but the rose gold bracelet example's set substitutes an Extract from the Archives alongside its manual, so confirm whether the example's paperwork is the original card, an archive extract, or both. Where a set lists additional straps, as the yellow gold blue dial set does with its extra alligator strap, confirm they are physically present. And match the full reference, metal code and strap segment included, between the watch and its paperwork: on this reference the suffix is the difference between a bracelet watch and a strap watch.
