RM 61-01 made its debut in 2014 and was worn by Jamaican sprinter John Blake, the younger brother of the tourbillon RM 59-01. Since 2012, this “ultimate edition” heralds the last question who has always been the Richard Mille family A member of this model with a very unique shape.
For the RM 61-01 Ultimate Edition, the TZP ceramics previously used on the bezel and back cover will be replaced by new materials such as quartz TPT and carbon TPT-the latter is also on the case. Multi-layer silica-based quartz TPT, no more than 45 microns thick, is interwoven with carbon TPT layers because they are stacked by an automatic compilation system, and the fiber direction between each layer changes 45 degrees. Heated to 120 degrees at a pressure of 6 bar in an autoclave, the 600-layer composite is ready for processing at the Richard Mille factory. Milling and turning generate random and unique patterns of quartz TPT and carbon TPT for each product. The carbon fiber TPT crown protector can avoid rubbing the wrist during sports activities. quality replica watch
The skeletonized movement RMUL2 is made of PVD-treated grade 5 titanium, black galvanized and hand-painted grade 5 titanium crosses the balance bridge, and a free-spring balance with variable inertia that oscillates at a frequency of 4 Hz. The dual-spring system distributes the stored energy to the two mainspring barrels to reduce pressure and friction on the gear teeth, bearings and pivots, thereby improving long-term performance.
The hand-wound movement provides a 55-hour power reserve and high impact resistance with an impact test of more than 5.000 grams. Richard Mille swiss
