As usual with Richard Mille watches, the case of the 61-01 is secured by spline screws in grade 5 titanium. Inside the Richard Mille RM 61-01 Yohan Blake Limited Edition ticks the calibre RMUL2. It is a fully skeletonized manually wound engine that boasts 55h hours of power reserve thanks to a double barrel mechanism that helps to improve torque stability by reducing pressure and friction on the gears. This movement feels really light, not to say brittle. All the bridges are very thin and opened to show every technical element of the movement.
The calibre RMUL2 features Richard Mille usual but superb finishing: bridges and baseplate made in grade 5 titanium and coated with black PVD, hand polished bevelled angles, straight grained finish on steel parts, wet sanded by hand finishing on titanium parts, burnished pivots, screw slots and screws bevelled and polished. This looks like modern and technical horology, but trust us, it uses the traditional haute horlogerie skills in a very modern interpretation.
