The Richard Mille RM030 AM CA Japan Limited Edition combines cutting-edge mechanics with a modern, lightweight design, exclusively crafted for the Japanese market. The 50mm tonneau-shaped case, built from carbon and ceramic, houses the automatic RMAR1 caliber. This skeletonized movement features hours, minutes, seconds, a date display, power reserve indicator, and a patented declutchable variable-geometry rotor. Engineered for precision, the rotor automatically disengages when the power reserve reaches 50 hours to prevent overwinding and re-engages at 40 hours, ensuring consistent torque and optimal performance. The grey skeletonized dial displays a rewinding indicator at 12 o’clock, providing clear visual cues for the rotor’s operating phase. With a 55-hour power reserve and luminescent Arabic numerals, the RM030 is designed for both function and clarity. Paired with a white rubber strap and titanium deployment clasp, this timepiece is lightweight, durable, and water-resistant to 50 meters, making it a true testament to Richard Mille’s innovative craftsmanship.
