"The RM 61-01 Yohan Blake takes all of its cues from the RM 59-01 tourbillon launched for the Olympic medalist and 2nd fastest man over 100m and 200m. 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’. The bezel and the back of the RM 61-01 are created from TZP-N, the caliber RMUL2 with its highly skeletonised grade 5 titanium movement treated with PVD and Titalyt® to provide maximum performance. Accentuating the tough character of this novel timepiece are the large crown protectors, offering full security to the crown during sports and other activities."
