Richard Mille is no stranger to exotic luxury, the RM 052 Skull Tourbillon (first released in 2012) being a perfect example. This amazing watch is as alluring and peculiar as the mysterious crystal skulls of ancient times. The distinctive timepiece includes a skull shaped base plate made of grade 5 titanium, with jaws that hold up the tourbillon cage jewel. With an artistic, hi-tech case requiring an impressive 86 stamping and 255 machining operations to complete, the attention to detail and intricacy behind the tourbillon's design are blatantly obvious. The Richard Mille RM52 Tourbillon Skull is a limited edition of 21 pieces (15 in titanium and 6 unique pieces in rose or white gold), which high-end watch collectors and enthusiasts love and cherish. The hypnotically eerie skull in the center is held up by four bridges that resemble the cross bones. Through the anti-reflective display case back, one can appreciate a full view of the winding wheels and jewels.
