The Richard Mille RM 055 Bubba Watson is a high-performance timepiece designed for sports enthusiasts, particularly golfers. Its skeletonized movement, crafted from grade 5 titanium, offers exceptional durability and precision. The case features a combination of materials, including a bezel made from yttria-stabilized zirconia (ATZ) ceramic, known for its hardness and scratch resistance, and a caseband and back bezel in grade 5 titanium with a protective white rubber casing. This design ensures the watch can withstand accelerations of over 500 g's, making it suitable for high-impact activities. The RM 055 is available in various editions, including the All Grey Boutique Edition, which features a shot-blasted titanium carbide bezel and a monochromatic grey aesthetic.
