The Audemars Piguet Royal Oak “Jumbo” Extra-Thin that matches the titanium-and-Bulk Metallic Glass description is reference 16202XT.OO.1240XT.01. Its official U.S. product page lists an extra-light titanium case, a smoked burgundy dial, and a Bulk Metallic Glass (BMG) bezel. It is a series-produced model introduced in 2023, distinct from the one-of-a-kind titanium-and-BMG 15202XT created for the 2021 Only Watch charity auction. This is a reference guide, not a report of an independent physical inspection.
Which Royal Oak Jumbo titanium and BMG watch is this?
The specific model is the Royal Oak “Jumbo” Extra-Thin reference 16202XT.OO.1240XT.01. Audemars Piguet’s U.S. product page identifies its smoked burgundy dial, extra-light titanium case, and BMG bezel. The official page is the best reference for the listed configuration; it does not establish current availability or retail price.
“Jumbo” is the familiar name for the extra-thin Royal Oak line. The material combination has appeared in two easily confused references, but they are not the same watch: the 15202XT was a unique auction piece, while the 16202XT is the later series-produced model.
How the 2021 15202XT differs from the 16202XT
| Reference | Status and date | Movement | Documented materials and dial |
|---|---|---|---|
| 15202XT | One-of-a-kind watch made for the 2021 Only Watch charity auction, according to Audemars Piguet. | Calibre 2121, according to Audemars Piguet’s Jumbo history. | AP describes sandblasted titanium and polished BMG. The available source does not state a dial description for this comparison. |
| 16202XT.OO.1240XT.01 | Series-produced BMG Jumbo, associated with 2023 by AP’s materials history. | Calibre 7121, the movement AP associates with the newer Jumbo generation in its model history. | Extra-light titanium case, BMG bezel, and smoked burgundy dial, as listed on the official product page. |
The distinction matters when reading descriptions or comparing images: specifications for the unique 15202XT should not automatically be applied to the 16202XT. In particular, AP’s detailed description of the 2021 watch’s bracelet does not confirm every bracelet construction detail for the later reference.

What Bulk Metallic Glass adds
Audemars Piguet describes the BMG used in its Royal Oak Jumbo as palladium-based. The brand says palladium contributes wear and corrosion resistance and added brilliance, and characterizes BMG as lighter and stronger than platinum. Those are manufacturer claims; the cited material does not provide independent comparative test results for the components in this watch.
AP’s materials history says: “The alloy used by Audemars Piguet since 2021 is the first to be based on precious metals.” Its separate account of the 2021 15202XT describes that alloy as Pd500, with at least 50% palladium. That composition and hallmark are documented for the 2021 piece; they should not be treated as confirmed specifications for the 16202XT without reference-specific confirmation.

Titanium, BMG, and the bracelet details
The official 16202XT listing establishes the titanium case and BMG bezel, while the bracelet’s exact material breakdown is not stated in the cited product-page information. For the earlier 2021 15202XT, AP’s bracelet account describes sandblasted titanium links with polished BMG studs and says the new materials required new manufacturing techniques and tools. That description is useful context for the design, but it belongs to the unique 15202XT rather than serving as proof of identical construction on every BMG Jumbo.
In a Royal Oak, the integrated bracelet is a conspicuous part of the overall design, not merely a strap attached to the case. Here, the material contrast is central to the appeal: titanium supplies the lightweight case construction, while BMG introduces a different finish and material character at the bezel. The precise split of materials across the 16202XT bracelet should be checked against reference-specific documentation.

The Jumbo movement change: calibre 2121 to 7121
Audemars Piguet says the original calibre 2121 was introduced in the Royal Oak in 1972 and retired at the end of 2021. The newer selfwinding calibre 7121 was designed for the extra-thin Jumbo case. AP gives the movement’s thickness as 3.2 mm and the case thickness as 8.1 mm in its official Jumbo history. Those are the brand’s stated figures for the newer movement and Jumbo case; they are not independent measurements of an individual 16202XT.
The transition provides useful context for separating the references: AP associates the 2021 unique 15202XT with the 2121 generation and the later series-produced 16202XT with the 7121 generation. The movement change is part of the model’s technical evolution, rather than evidence that the older and newer titanium/BMG watches are interchangeable specifications.
