Richard Mille RM 52-01s Skull Edition Wristwatch.

New from Richard Mille comes the second model in the Skull collection, the RM 52-01s, which takes the skull concept to extremes, making a bold statement, exploding the skull logo in hand bevelled red gold in the centre of a PVD treated titanium baseplate, and all housed in a completely new nano-ceramic composite that they are calling TZP, which is finished with microblasting, and hand polished on the corners.

But with Richard Mille the case is only part of the story, the movement is the star, with a tourbillon in the jaws of the skull, just peeking through the mouth, the manual winding caliber is very similar to the one used on the RM 52-01, the free sprung balance with variable inertia, a fast rotating barrel, and a barrel pawl with progressive recoil, all contribute to the 48 hour power reserve this baby can have, making this 50mm cased watch, which is limited to 30 pieces worldwide, well worth the £175,000 price tag being asked.
