Overview
Colourless sapphire, with the suspension system fully exposed
This execution uses colourless sapphire, which leaves nothing between the eye and the mechanism: the braided cables, the pulleys they pass over and the tensioning arrangement are all legible, as is the skeletonised movement they carry.
The cable measures 0.27 mm. The strap is white and the crown blue.

Design and engineering
- Colourless sapphire caseTransparent because of the purity of its composition, and at 1,800 Vickers effectively scratch-proof except by diamond.
- Exposed cable suspensionThe pulleys and cable runs are part of the visual composition rather than concealed behind a case wall.
- Shock isolation by suspensionThe movement floats within the case; impacts are taken by the cable system.
- Skeletonised grade 5 titanium structureCut back as far as the mechanical properties allow.
- Manual-winding tourbillonHours and minutes.
- Sapphire casebackThe suspension reads identically from the reverse.
