For this limited edition, the "all black" scheme is replacing the green and yellow colors of the 61-01. The RM 61-01 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 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.
Limited Edition of 100 pieces.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES 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.
FREE SPRUNG BALANCE WITH VARIABLE INERTIA This type of balance wheel ensures greater reliability in the event of impact as well as during assembly and disassembly of the movement. This improves precision in the long term. There is no need for an index and it is possible to adjust the inertia more finely directly on the balance wheel via 4 small adjustable small weights.
BASEPLATE AND BRIDGES IN GRADE 5 TITANIUM The manufacturing of these components in grade 5 titanium with black PVD coating for the baseplate 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 baseplate and the bridges have been subjected to complete validation tests to optimise their stress resistance.
CALIBER RMUL2 Manual winding skeletonised movement with hours, minutes and seconds; inspired by caliber RMUL1. Movement weight: circa 4.3 g.
