An AP skeleton watch is what Audemars Piguet calls an openworked watch: the dial and movement are cut away so you see the mechanism, and the best-known are Royal Oaks, from the Double Balance Wheel Openworked to openworked tourbillons. Our live listings start at $83,699 for an earlier 39 mm openworked Royal Oak and $150,659 for a Double Balance Wheel Openworked, each sourced to order and reserved with a $200 deposit credited to the price.
Sizes, calibres and power reserves come from Audemars Piguet's reference pages; discontinued references are described from our listings. Prices are the lowest live ask on 12 October 2026, linked to that exact watch.

Audemars Piguet calls its skeleton watches "openworked": the dial and the movement's bridges are cut away so you can see the mechanism. Most are Royal Oaks, but the Royal Oak Concept, Code 11.59 and the discontinued Millenary have openworked models too.
The Double Balance Wheel Openworked fixes a second balance wheel and balance spring on the same axis, a patented Audemars Piguet design meant to improve precision and stability; it runs the selfwinding Calibre 3132 with 45 hours of power reserve. The openworked tourbillons use a rotating cage instead: the Tourbillon Extra-Thin Openworked is hand-wound (Calibre 2924, 69 hours) and the Selfwinding Flying Tourbillon Openworked winds itself (Calibre 2972, 65 hours), and both cost more.
Yes. The Royal Oak Double Balance Wheel Openworked 15416CE has a black ceramic case and bracelet with a slate grey openworked dial (41 mm, 9.7 mm thick) and starts at $319,300 in our listings. The black ceramic Perpetual Calendar Openworked 26585CE, with a sapphire dial, starts at $412,000 and the Tourbillon Chronograph Openworked 26343CE at $342,474. In the Code 11.59 line, the Selfwinding Flying Tourbillon Openworked 26601NR pairs a black ceramic middle case with pink gold, from $249,999.
37 mm (10 mm thick) for the 15466 to 15469 Double Balance Wheel models, 39 mm for the "Jumbo" Extra-Thin Openworked 16204 (8.1 mm thick), 41 mm for the 15407 (9.9 mm in steel), the ceramic 15416CE (9.7 mm) and the openworked tourbillons (9 mm for the 26518, 10.6 mm for the 26735), and 44 mm for the tourbillon chronographs.
Most openworked Royal Oaks are selfwinding: Calibre 3132 in the Double Balance Wheel Openworked, 7124 in the "Jumbo" 16204, 2972 in the Selfwinding Flying Tourbillon Openworked and 5135 in the Perpetual Calendar Openworked. The Tourbillon Extra-Thin Openworked 26518 (Calibre 2924), the Royal Oak Offshore Tourbillon Chronograph 26407 (Calibre 2943) and the Code 11.59 Tourbillon Openworked (Calibre 2948) are hand-wound.
