The 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.
Boasting a highly skeletonised calibre crafted of PVD-treated grade 5 titanium, The RM 61-01 ensures superlative performance thanks and impact resistance tested for impacts of over 5,000 g’s.
Skeletonised manual winding movement with hours, minutes and seconds.
Circa 55 hours (± 10%).
These components, crafted in grade 5 titanium with black PVD coating, confer great rigidity on the whole assembly, as well as the precise surface flatness essential for perfect functioning of the gear train.
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.
This guarantees greater reliability when subjected to shock and during movement assembly or disassembly, hence better chronometric results over time.
The regulator index has been eliminated, guaranteeing a more accurate and repeatable calibration thanks to 4 small adjustable weights located directly on the balance.
DOUBLE-BARREL SYSTEM
The double-barrel system helps to improve torque stability over a longer period. This is achieved by distributing the stored energy across two winding barrels instead of one, which increases the number of rotations and reduces pressure on the teeth, bearings and pivots, resulting in better long-term performance.

ASYMETRICAL CASE
The bezel and the back of the RM 61-01 are created from black TZP ceramic. This ultra-tough ceramic material has a low density (6g/cm3) combining extreme resistance to scratches with a very low thermal conductivity coefficient. Composed of 95% zirconia (Zr02) stabilized with yttrium, TZP provides a perfect finish with blasted and hand-polished anglage in combination with a caseband created from light and highly resilient Carbon TPT®.
Its drawn-out shape between 2 and 5 o’clock prevents the crown from rubbing against the sprinter's wrist.
Accentuating the tough character of this timepiece are the large crown protectors, offering full security to the crown during sports and other activities.
The RM 61-01 case is water resistant to 50 metres. It is assembled with 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
FINISHING
• Baseplate wet sandblasted grade 5 titanium, PVD treated and hand-drawn after treatment
• Hand-polished locking sections
• Burnished pivots
• Pinions with undercuts
• Screw slot and screws bevelled and polished with a rounded and polished tip
• Straight line grain finish of the upper surface
• Microblasted lower surfaces
• Hand-polished sinks
• Sandblasted and rhodium-plated, bevelled wheels (before cutting the teeth)
• Minimum corrections applied to the wheels in order to preserve geometry and performance
OTHER FEATURES
In Carbon TPT® with Alcryn® collar.
Bezel side: in sapphire (1,800 Vickers) with anti-glare coating (both sides).
Thickness: 1.50 mm
Case back: in sapphire with anti-glare coating (both sides).
Thickness: at the center 1.20 mm and outer edges 1.95 mm.
This permits better control of the torque applied to screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
