Richard Mille - RM055 Bubba Watson Black Edition Black CER/RU Black Rehaut Skeleton UMI RMUL2 Free Sprung

RM055 / RM061 Haute Couture Edition

Case

Every detail of the case—dimensions, materials, and color—has been subjected to an uncompromising 24-month development cycle. Through countless revisions and precision calibrations, UMI achieves a level of tactile refinement and structural excellence that transcends its category, delivering a case with truly exceptional presence and craftsmanship.

Crystal

The crystal is sculpted from a single solid block of sapphire, then perfected through advanced multi-axis polishing. Finished with dual-sided nano-scale anti-reflective coatings, reflections are reduced to an absolute minimum. The result is breathtaking transparency—so clear and luminous it feels as though no glass exists at all.

Movement

Powering this masterpiece is a custom free-sprung integrated RMUL2 movement. Every gear, screw, plate, and bridge undergoes specialized treatment to ensure uncompromising precision and authenticity. This meticulous process preserves not only the movement’s performance, but its very essence and mechanical soul.

Strap

A high-density fluororubber strap is engineered to resist sweat, heat, and ultraviolet exposure. Enhanced through a multi-stage vulcanization process, it delivers exceptional durability while remaining supple on the wrist. The strap is secured by a Grade 5 titanium folding clasp, combining lightweight comfort with remarkable strength for an instantly elevated wearing experience.
