Skeleton & Openworked Dial Watches
Skeleton — also called openworked — dials remove the dial layer to expose the movement underneath. Audemars Piguet's Royal Oak Double Balance Wheel Openworked, AP Code 11.59 Flying Tourbillon, Hublot Big Bang Unico Sapphire, and Richard Mille's tourbillon references are the most accomplished modern skeletons.
