The Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked reference 16204XT.OO.1240XT.01 is the titanium-and-BMG interpretation of the openworked 16204. Audemars Piguet identifies the watch’s materials and its selfwinding Calibre 7124; the manufacturer page available here does not provide a complete specification table or a verifiable current price.
What is the Audemars Piguet 16204XT?
It is an openworked Royal Oak “Jumbo” Extra-Thin in the 16204 family. The exact manufacturer reference is 16204XT.OO.1240XT.01. Audemars Piguet presents this version in titanium with BMG accents and pairs it with Calibre 7124. Audemars Piguet’s product page confirms the reference and material presentation, but its accessible text does not expose a full specification table.
The 16204 openworked line debuted in 2022 for the Royal Oak’s 50th anniversary, initially in stainless steel and 18-carat pink gold. The XT is a distinct material treatment of that openworked design, rather than a different movement family.
What are the case materials and dimensions?
Audemars Piguet identifies the 16204XT as titanium with BMG accents. BMG means bulk metallic glass; the official page establishes its use as an accent material but the accessible text does not specify the individual components that use it.

Time and Watches reported a 39 mm diameter and 8.1 mm case thickness for the 16204XT in its March 5, 2026 coverage. Those are secondary-source figures: the accessible AP product-page text does not confirm them in a complete specification table. The 2.7 mm figure sometimes associated with this watch is the height of its movement, not the case.
Which movement is inside, and what does openworked mean?
The watch uses Calibre 7124, an automatic (selfwinding) openworked movement. Audemars Piguet Heritage gives its thickness as 2.7 mm and notes that it has no date indication. The absence of a date is part of the movement’s display layout, not a missing setting on a dated version.

How the movement is openworked
Audemars Piguet describes a process in which CNC machining starts the geometry of the mainplate and bridges, followed by electrical discharge machining and traditional finishing of the components. The manufacturer says the movement has 324 V-angles, all finished by hand; this is AP’s published count, not an independently audited measurement.
Why is it called “Jumbo”?
“Jumbo” is a historical name for extra-thin 39 mm Royal Oak models, not a claim that the watch is unusually large by current sizing conventions. The original 1972 Royal Oak 5402 measured 39 mm across and approximately 7.15 mm thick, according to Audemars Piguet Heritage. Its relatively generous diameter combined with a thin profile helped establish the sport-chic proportions.

Audemars Piguet’s Heritage editorial board explains that the nickname was retained for “extra-thin 39 mm models exclusively.” The openworked 16204 line carries that lineage forward with a dedicated movement, Calibre 7124, rather than the date-displaying Calibre 7121.
