Richard Mille RM61-01 Yohan Blake Ultimate Edition Limited 150 pieces (046/150)

This limited edition RM 61-01 Yohan Blake takes all of its cues from the RM 59-01 tourbillon designed for the Olympic medallist and 2nd fastest man over 100m and 200m. It incorporates the calibre RMUL2, whose highly skeletonised grade 5 titanium movement is treated with PVD and 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 timepiece are the large crown protectors, offering full security to the crown during sports and other activities.
