The watch combines the caliber RMUL2 with its highly skeletonised grade 5 titanium movement treated with PVD nd Titalyt® to provide maximum performance.
The bezel and the back of the RM 61-01 are created from TZP-N. This ultra-tough black ceramic material has a low density (6g.cm3) combining extreme resistance to scratches with a very low coefficient of thermal conductivity. Composed of 95% Zirconium compound stabilized with Yttrium, TZP-N provides a perfect finish with blasted and hand polished anglage in combination with a caseband created from light and highly resilient NTPT® carbon. Its drawn-out shape between 2 and 5 o’clock stops the crown from rubbing against the sprinter handle.
The skeletonised RMUL2 movement with 55 hours power reserve is built in grade 5 titanium treated with PVD and Titalyt® using a free sprung balance beating at 4Hz. Developed with sporting applications in mind, Richard Mille has consciously aimed for exceptional impact resistance, with validation testing for the RM 61-01 carried out in excess of 5000 G’s.
Accentuating the tough character of this novel timepiece are the large crown protectors, offering full security to the crown during sports and other activities..
The green flying bridges, woven into the front of the movement, are anodized and painted by hand, bringing to mind the colors of his Jamaican homeland, together with Yohan Blake’s nickname ‘The Beast’, a name imparted to him during his amazing record breaking perfomances on athletics tracks around the world.
