Richard Mille RM 010

The RM 010 is a line of automatic Richard Mille watches in a tonneau case, introduced in 2006. It continued the RM 005 with a larger case.

Inside is the automatic RMAS7 calibre with a variable-geometry rotor, which allows the winding to be adjusted to the owner's level of activity. The baseplate and bridges are machined from Grade 5 titanium, and the case is held together with the brand's spline screws in the same alloy. The case measures 48 × 39.30 × 13.84 mm, the power reserve is 55 hours, and the watch has a sapphire crystal and transparent caseback. The dial is skeletonised, with the date at 7 o'clock.

These are men's watches in white gold and titanium cases, on a rubber strap with a folding clasp. The choice within the collection comes down to material: the titanium tonneau is barely noticeable on the wrist, while the gold one is markedly heavier. Related Richard Mille lines include its predecessor, the RM 005, as well as the RM 011 and RM 055.
