This unworn Richard Mille RM 07-01 is a women’s watch in an 18k white gold tonneau case, 31.4mm across (45.66mm long). The bezel and lugs are set with diamonds in vertical channels. The dial is skeletonized, with a black onyx oval ringed in diamonds. There are no hour numerals; time is read from luminous drop markers and sword hands.

Richard Mille is printed in gold at 12. The crown is gold with a black rubber grip. Inside is the automatic CRMA2 caliber, a skeleton movement with a variable-geometry rotor and about 50 hours of power reserve. Sapphire crystal. Water resistance is 50 meters. It comes on a black rubber strap with a folding clasp, plus the original box and papers.

Functions are hours and minutes. The case uses Richard Mille’s spline screws. White gold and diamonds sit against the black onyx and black strap. Grade 5 titanium plates sit under the open dial.
