Richard Mille | Reference rm010ti | A Grade 5 Titanium Automatic Tonneau Wristwatch

The Richard Mille RM 010 Automatic represents a defining milestone in contemporary technical horology. Conceived as the larger, fully skeletonised evolution of the RM 005, the RM 010 exemplifies the manufacture’s uncompromising architectural design philosophy. Its openwork display exposes every internal mechanical organ with absolute transparency, transforming functional timekeeping into three-dimensional sculpture.

Powering the watch is Calibre RMAS7, an automatic skeletonised movement measuring 30.20 by 28.60 millimetres with a thickness of 6.35 millimetres. The mechanism features 32 jewels, operates at a frequency of 28,800 vibrations per hour, and offers an approximate power reserve of 55 hours. Central hours, minutes, and seconds are complemented by a semi-instantaneous date aperture neatly positioned at 7 o’clock.

The calibre incorporates an ingenious variable-geometry rotor constructed with a heavy tungsten-cobalt weight segment, 18k high-palladium white gold wings, and grade 2 titanium arms to adapt winding performance to wearer activity. The baseplate and bridges are machined from grade 5 titanium—composed of 90 percent titanium, 6 percent aluminium, and 4 percent vanadium—with meticulous ribbing for supreme rigidity.

The iconic tripartite tonneau case measures 48.00 by 39.30 millimetres with a thickness of 13.84 millimetres, assembled with twelve grade 5 titanium spline screws and abrasion-resistant washers. Rated to 50 metres of water resistance, the curved architecture hugs the wrist naturally, delivering an exceptionally balanced, featherweight, and ergonomic wearing experience for all-day comfort.
