In 2011, the RM030 collection marked a significant milestone for Richard Mille with its introduction of the automatic self-winding movement cal. RMAR1. The concept of an automatic movement is to wind the watch through the movements of the wearer. However, to avoid overwinding once the power is full, classic conventional systems utilize a sliding flange that could possibly introduce harmful debris into the winding barrel particularly when the wearer is highly active. This can adversely affect the watch's chronometric performance.
After four years of extensive research and development, Richard Mille designed a new rotor that automatically declutches when the power reserve reaches 50 hours, and it re-engages when the power reserve decreases to 40 hours. This extraordinary technical achievement allows both the movement and the oscillator to maintain the best ratio of constant torque and power, resulting in optimal chronometric performance.
The current iteration of the RM030 is a limited edition of only 50 pieces created specifically for the Japanese market. Featuring a robust ATZ ceramic case made from aluminum oxide powder tubes, it was injected at a pressure of a whopping 2,000 bar. With the rigidity increased through the process, it is one of the hardest materials in the world comparable to diamond. Notably, ATZ ceramic is highly hypoallergenic and exhibits exceptional resistance to scratches, shocks, and abrasion, making it an ideal material for a watch case.
Fresh-to-the-market and the first time this reference has appeared in auction, the watch is very versatile especially when equipped with the Velcro strap. Further accompanied by its full set of accessories, the watch is no doubt a masterclass by Richard Mille showcasing how a perfect automatic movement should be made.
