Overview
Snow-set white gold with red gold furniture and an onyx centre
The white gold case is snow set throughout the bezel and caseband. The dial-centre plate carries a white metal frame set with stones around an onyx panel, the black stone setting the openworked calibre off against a flat field.
The crown, the pushers and the inner flange ring are red gold, the hands are gold and the strap is black rubber.

Design and engineering
- Onyx dial centreA black stone panel set into the centre plate, giving a flat, uniform field for the hands to read against.
- Snow settingStones of differing diameters are placed to fill the surface without a repeating grid, so that no metal shows between them. It is a technique rather than a point on the coverage scale that runs from unset through one row and mid to full.
- Red gold furnitureThe crown, pushers and inner flange ring are red gold against the white gold case; the dial-centre frame is white metal, set to match the case.
- Oversize dateSemi-instantaneous, placed horizontally under 12 o’clock, driven by two skeletonised calendar discs over a white field.
- Function selectorA push-button at 4 o’clock selects winding, neutral and hand-setting with a single push; an aperture at 4 o’clock shows W, N or H. A second push-button at 10 o’clock corrects the date.
- Baseplate and bridges in grade 5 titaniumMicroblasted and electroplasma treated for rigidity and the surface flatness the gear train requires, then validation-tested separately for strength.
