The entire case - front bezel, caseband, back of the RM 56-01 are cut and milled from solid blocks of sapphire.
No external structures are used to support the assembled parts. Sapphire is known as a particularly scratch-resistant material with a hardness of 1800 Vickers. Made of aluminium oxide (Al2O3) crystals, it is transparent thanks to its molecular composition. exceptionally delicate.
1000 hours of machining, of which 430 hours were spent on pre-forming the case components and 350 hours on polishing the whole watch case. For excellent optical properties, the front bezel and the back bezel have been treated with an anti-glare coating. The tripartite case is water resistant to 30 meters, ensured by two Nitril O-ring seals.
The case is assembled with 24 spline screws in grade 5 titanium and abrasion resistant washers in 316L stainless steel.

This permits better control of the torque applied to the screws during assembly.
These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

In sapphire (thickness: 0.40 mm) with anti-glare treatment (both sides), protected by 8 silicon braces inserted in the upper and lower flanges grooves
