Part watch, part work of art, the Richard Mille x Pharrell RM 52-05 is an ambitious space-themed timepiece. It's powered by a manual winding tourbillon movement, featuring a grade 5 titanium baseplate and bridges, with blue aventurine glass inserts that resemble space visible through the crystal caseback. On the front, a helmet and spacesuit structure is also made from grade 5 titanium, connecting to the movement underneath. Diamonds and black sapphires on either side of the helmet represent projectors and cameras, while the curved 5N gold visor was engraved, grand-feu-enameled and then hand-painted to depict an astronaut's view of Earth from Mars. Brown Cermet is used to craft the bezel and case back perimeter, both of which are affixed to a caseband made from carbon TPT. It's finished with an orange rubber strap and is sure to be highly limited.
