GETDipped: Audemars Piguet Royal Oak Concept GMT Tourbillon

The 44mm titanium case is hardened by anodization, and houses a twin-barrel, manually wound, in-house movement with tourbillon and GMT, fixed to a white rubber strap with folding clasp. Almost completely scratch-proof, the white ceramic bezel is cut by diamond-tipped machines and takes over eight hours to create, compared with around 45 minutes for a steel bezel.
