Richard Mille‘s RM 052 Skull is a limited edition of 21 watches, introduced at SIHH 2012. The watch had a price of $500,000 when it was first announced. The watch’s main feature is the skull-shaped grade 5 titanium baseplate at the center. The skull is also integrated into the movement: the upper and lower “jaws” hold the ruby of the tourbillon cage, and the back of the skull is also the movement’s center bridge. The four bridges that connect the movement to the case also a form a skull-and-crossbones pattern.
