Powering the RM 037 is the new CRMA1 caliber, a high-tech movement which is skeletonized in grade 5 titanium. It features an oversized date at 12 o’clock and a function window at 4 o’clock. A pusher at 4 o’clock allows the wearer to select the mode: (W) winding, (N) neutral and (H) hand setting functions with a simple push. An aperture a 4 o’clock shows the function selected. A pusher at 10 o’clock controls date changes, useful when the date needs to be corrected or adjusted.
“Forty-four different stamping operations are required for the three main components of the case (bezel, caseband, and case back). The machine tooling process requires two days of adjustment for the bezel, two days for the caseband and two days for the case back. The empty case requires more than 255 tooling operations and more than five hours of glazing and polishing in the final stage.”
The complex case shape is obtained using a high-tech five-axis machine. The “Richard Mille” engraving on the back and inside curves of the case requires 45 hours per timepiece. The case is water-resistant to 50 meters, ensured by two Nitril O-ring seals. The case assembly uses 20 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
