Overview
Black ceramic and rubberised titanium, with red gold on the flange
The Asia Edition places a black ATZ ceramic bezel and caseback around a rubberised titanium case middle, with red gold picking out the inner flange, the hands and the crown ring against the darkened case.
The calibre RMUL2 inside is a skeletonised manual-winding movement in grade 5 titanium, built to take the accelerations a golf swing puts through a watch. The strap is black.

Design and engineering
- ATZ ceramicMade from tubes of aluminium oxide powder injected at close to 2,000 bar. The high-pressure injection raises rigidity by 20 to 30% and reduces porosity to a minimum, giving 1,400 Vickers of scratch resistance and a colour that does not change. Machining the curved bezel requires diamond tooling.
- Rubberised titanium case middleRubber is injected at high pressure around the titanium components, insulating the movement from vibration and making the watch more comfortable on the wrist.
- Calibre RMUL2Grade 5 titanium, extremely skeletonised, PVD and Titalyt® treated.
- Free-sprung balance with variable inertiaThe regulator index is eliminated; four small weights set directly on the balance allow accurate and repeatable adjustment.
- Double barrelEnergy is spread across two barrels, equalising torque and reducing pressure and friction on bearings and pivots.
- Spline screws in several sizesSeveral sizes, in both case and movement, giving controlled torque at assembly and surviving repeated dismantling.
