Overview
Layered carbon with a red gold flange
The bezel and caseback are NTPT carbon, the layered striations of the material running across both, with red gold on the inner flange and hands and a blue accent ring framing the movement. The strap is black.
The calibre RMUL2 is a skeletonised manual-winding movement in grade 5 titanium, developed so that a watch could stay on the wrist through a professional golf swing.

Design and engineering
- NTPT carbonLayers of carbon filament laid at rotating angles and cured under heat and pressure, giving each case a striation pattern of its own.
- 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.
- Red gold flange and handsSet against the dark composite, with a blue accent ring framing the movement.
- Spline screws in several sizesSeveral sizes, in both case and movement, giving controlled torque at assembly and surviving repeated dismantling.
