Movement & Performance
Nicknamed the "Baby Bubba," the RM 055 was built to survive the extreme physical demands of a professional golf swing, mirroring the DNA of the million-dollar RM 038 tourbillon.
- Calibre RMUL2: This manual-winding skeletonized movement weighs a mere 4.3 grams. The baseplate and bridges are made of Grade 5 titanium with a black PVD and Titalyte treatment, creating a deep visual contrast against the white case.
- Suspended Architecture: The movement is not screwed directly into the case; instead, it is secured by four transparent elastomer shock absorbers. This "floating" design allows the watch to withstand accelerations of over 500 G’s.
- Dual Barrel System: It features a 55-hour power reserve. The twin-barrel system helps improve torque stability over the long term, ensuring the movement remains accurate even as the power winds down.
