Richard mille RM 62-01 Manual Winding Tourbillon vibrating alarm ACJ

The RM 62-01 exemplifies the entire Richard Mille philosophy: taking functionality and performance to new limits. From its complexity, to its complications, to its ergonomics, this piece constitutes a total work of haute horlogerie.

The caseback and bezel are comprised of a first bezel in polished and satin-finished grade 5 titanium, to which is affixed a second bezel, just 1.80 mm in thickness, machined from Carbon TPT®. This high-tech material is made up of 600 layers of parallel filaments obtained by separating out carbon fibres. The layers, no more than 30 microns thick, are impregnated with a black resin. They are then assembled on a dedicated machine, which stacks the layers, varying the orientation of the fibres by 45° between layers. The composite is then hardened heated to 120°C at a pressure of 6 bars in a kiln similar to that used for the production of aeronautics parts, after which it is ready to be machined at Richard Mille. During this phase, the many layers of Carbon TPT® are revealed, creating random damascene patterns that make each piece unique.

The caseband and pushers are also milled from Carbon TPT® enhanced with stiffeners in microblasted and polished grade 5 titanium. The case is assembled with 20 Torq-Set® screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.

Like the blades of a propeller, the four arms that characterise a Torq-Set® screw head converge on the centre in an offset cruciform manner with curved trajectory. This type of screw is employed in the aerospace industry to ensure optimal control and transmission of torque. Superior to a traditional Phillips screw, its form also ensures flawless positioning for quick assembly and disassembly under any conditions
