Overview
The 2015 successor to the RM 033, with date and small seconds
The RM 33-01 followed the RM 033 in 2015. It retains the round tripartite case construction — front bezel, caseband, back bezel — and the off-centre platinum micro-rotor, but the calibre gains a date display and a small seconds subdial, and the case grows in height from 6.30 mm to 9.20 mm at the same 45.70 mm diameter.
The small seconds subdial, with a red-tipped hand, sits at 6 o’clock and the date aperture at 7 o’clock. The baseplate and bridges are grade 5 titanium, sandblasted and electroplasma treated, with satin-finished surfaces and hand-applied chamfers.

Design and engineering
- Off-centre platinum micro-rotorRetained from the RM 033, winding the barrel from a decentralised position so that overall movement height stays low.
- Small seconds and dateThe small seconds subdial, with a red-tipped hand, sits at 6 o’clock; the date aperture at 7 o’clock.
- Grade 5 titanium calibreSandblasted and electroplasma treated, with satin-finished surfaces and hand-applied chamfers.
- Tripartite caseFront bezel, caseband and back bezel, assembled with 14 grade 5 titanium spline screws — the construction Richard Mille uses for both its round and its tonneau cases.
- Validation testingThe calibre was subjected to shock and temperature-variation testing as part of Richard Mille’s standard qualification programme.
