Review of Richard Mille RM055

Design & Case

Tonneau-Shape Titanium Case

Richard Mille’s signature tonneau-shaped case measures 49.90 mm × 42.70 mm × 13.05 mm, offering a bold wrist presence while remaining ergonomically curved for comfort. Constructed from sand-blasted Grade 5 titanium, the caseback and mid-case provide strength at a fraction of steel’s weight.

ATZ Ceramic Bezel

The RM 055 features a shot-blasted ATZ (Alumina-Titanium-Zirconia) ceramic bezel that resists scratches up to 1,400 Vickers and retains its color permanently . Machining this curved, complex bezel requires diamond tooling and lengthy polishing to achieve the signature satin finish and polished bevels.

Movement & Performance

Caliber RMUL2 Manual-Wind Skeleton

At its heart beats the manual-wind RMUL2 caliber, skeletonized and built in Grade 5 titanium with PVD and Titalyt®-coated bridges and baseplate for optimal rigidity and surface flatness. Running at 28,800 vph (4 Hz), this ultra-light 3.15 mm-thick movement weighs just 4.3 g and withstands accelerations over 500 g, making it ideal for sporting use.

Power Reserve & Precision

A double-barrel system delivers approximately 55 hours of power reserve while equalizing torque for long-term chronometric stability. The elimination of a regulator index in favor of four adjustable inertia weights on the balance wheel ensures repeatable, high-precision adjustment.

Dial & Strap

Skeletonized Display

With no traditional dial plate, the RM 055 exposes its gear train and balance wheel under a sapphire crystal, showcasing mechanical artistry and Richard Mille’s engineering ethos.

Integrated Rubber Strap

A white, integrated rubber strap with a Grade 5 titanium deployant buckle offers sporty resilience—resistant to sweat, UV, and moisture—while conforming comfortably to the wrist.

Wearability & Comfort

Despite its substantial case size, the RM 055 feels feather-light on the wrist thanks to its titanium construction and ergonomic contours. The high-pressure rubber-coated mid-case insulates the movement from shocks and vibrations, maintaining both comfort and performance during intense activity.

Value & Conclusion

Priced in the six-figure range (roughly CHF 105,500), the RM 055 is boutique-exclusive and produced in limited numbers (50 “Boutique Edition” and 100 “Limited Edition”). It represents the pinnacle of Richard Mille’s non-tourbillon sports watches: a unique combination of cutting-edge materials, avant-garde skeletonization, and long-term reliability. For collectors and enthusiasts seeking an ultra-light, high-tech timepiece that delivers both visual drama and shock-proof performance, the RM 055 “Bubba Watson” stands alone.
