Richard Mille likes the physical motions involved in this sport, which combine amplitude with precision, and the surprising sequence that contrasts moments of Zen-like preparation of concentration followed by the instantaneous shock of the shot, the long period of the ball’s trajectory and the subsequent walk to the next tee. This watch was directly linked to the developments that took place in creating the tourbillon model for Bubba Watson.
The experience in developing resistance to G forces in Richard Mille watches led to choose grade 5 titanium for the baseplate and bridges of this “skeletonised” movement, as it is a material that provides the rigidity required for the accuracy and reliability of the movement. Available in rubberized grade-5 titanium caseband and back with ATZ front bezel.
CALIBER RMUL2 Manual winding skeleton movement with hours, minutes and seconds; inspired by Caliber RM UL1. Movement weight: 4.3 grams.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE CASE Their shape allows better control of the torque applied to these screws during assembly. The screws are thus perfectly resistant to manipulation during assembly and disassembly and are exposed to minimal wear and tear.
CASE ATZ bezel case with a rubberized grade-5 titanium caseband and back. The ATZ bezel is based on aluminium oxide powder tubes injected at a pressure of 2,000 bar. This high-pressure injection increases rigidity by 20-30% and reduces the material's porosity to an absolute minimum. ATZ has the reputation of being a particularly scratch-resistant material (1,400 Vickers), and possessing an unchangeable colour. After diamond, it is one of the hardest materials in the world.
BASEPLATE AND BRIDGES IN TITANIUM The manufacturing of these components in grade 5 titanium with black PVD coating for the bottom plate and the bridges gives the whole assembly a great rigidity and achieves excellent surface flatness, essential to the perfect functioning of the gear train. The skeletonised bottom plate and the bridges have been subjected to complete validation tests to optimise their stress resistance.
