Inspired by the RM 038 Tourbillon created for the legendary golfer Bubba Watson, the RM 055 is a masterclass in manual-winding transparency and durability. It was engineered to conquer one of the most violent environments for a mechanical watch: the high-velocity, high-impact swing of a professional golfer. This timepiece is a statement of architectural purity, stripped of all excess to reveal the soul of the machine.
Case Architecture & Advanced Materials
Dimensions:49.90 mm (length) x 42.70 mm (width) x 13.05 mm (thickness).
Bezel (ATZ Ceramic):Crafted fromAlumina Toughened Zirconia. This high-performance ceramic is created by injecting aluminum oxide powder under 2,000 bars of pressure. It is one of the hardest materials in the world after diamond, offering extreme scratch resistance and a permanent matte finish.
Caseband & Caseback:Made fromGrade 5 Titaniumwith a specialized white rubber protective coating. This "rubberized" finish acts as a high-tech vibration damper to protect the movement from micro-shocks during high-impact activities (like a golf swing).
Weight:The entire movement weighs a mere4.3 grams.
Baseplate & Bridges:Manufactured fromGrade 5 Titanium(90% titanium, 6% aluminum, 4% vanadium). The assembly is treated with PVD (Physical Vapor Deposition) and Titalyt® to ensure extreme rigidity and perfectly flat surfaces, essential for the gear train's precision.
Shock Resistance:The movement is designed to withstand accelerations of over500 Gs, specifically engineered to handle the violent deceleration of a professional golf stroke.
Performance Metrics:
Power Reserve:Approximately 55 hours (± 10%) provided by a double-barrel system that improves torque stability.
Frequency:28,800 vibrations per hour (4 Hz).
Jewels:24.
Variable-Inertia Balance:This ensures greater reliability when subjected to shocks and during movement assembly/disassembly, leading to better chronometric results over time.
Aesthetics & Finishing
Skeletonization:Extreme removal of material from the bridges and mainplate to achieve a "floating" visual effect, allowing a clear view of the double-barrel and escapement.
Dial:Transparent sapphire (0.40 mm thick) with anti-glare treatment on both sides, protected by 8 silicone braces.
Hands:Open-worked hands in grade 5 titanium with luminescent coating for legibility.
Ergonomics & Resistance
Strap:High-grade white ventilated rubber strap with a titanium double-deployment buckle.
Water Resistance:30 meters (3 ATM), ensured by two Nitrile O-ring seals.
Crystal:Sapphire (1,800 Vickers) with a thickness of 1.20 mm at the center and 2.04 mm at the outer edges.
