Richard Mille - Titanium - RM 67-01 Bk TI

Crafted with precision, the RM 67-01 watch boasts a microblasted grade 5 titanium baseplate with a grey electroplasma treatment, ensuring exceptional rigidity and precise surface flatness for optimal gear train functionality. The bridges, also made of microblasted grade 5 titanium, undergo black electroplasma treatment for a sleek aesthetic.

Subjected to rigorous validation tests, the skeletonised baseplate and bridges meet optimal strength requirements. The movement features a platinum rotor with the OneWay® winding system and ceramic ball bearings, efficiently powering the barrel while maintaining an extra-flat, skeletonised design.

With dimensions of 29.10 x 31.25 mm and a thickness of 3.60 mm, the movement comprises 25 jewels, a CuBe balance with 4 arms and 4 setting screws, a moment of inertia of 7.5 mg•cm2, and a 50° angle of lift. Operating at a frequency of 28,800 vph (4 Hz), the balance spring is made of AK3, and shock protection is provided by INCABLOC 908.22.211.100 (transparent).

The distinctive tonneau shape, initially introduced in an extra-flat form for the RM 67-01 case, showcases meticulous craftsmanship. The complex machining process involves numerous stamping operations, meticulous adjustments, and weeks of preparation. The case undergoes manual brushing and polishing, assembly with sapphire glass, preliminary water-resistance testing, and final quality control.
