The Richard Mille RM 67-01 Extra Flat in Rose Gold redefines elegance through extreme engineering. Encased in 18-carat rose gold and measuring just 7.75 mm thick, this ultra-slim tonneau-shaped watch is one of the most refined pieces in the Richard Mille lineup. Despite its sleek profile, it retains the brand’s signature skeletonized aesthetic, showcasing the automatic Caliber CRMA6 — an in-house movement crafted from grade 5 titanium with hand-finished bridges and a 50-hour power reserve. The dial integrates luminous metal hour numerals mounted on titanium rails and a discreet function selector, offering a clean yet technical display. Paired with a black rubber strap and sapphire crystal, the RM 67-01 strikes a rare balance between lightweight sophistication and unmistakable Richard Mille identity.
