American golfer Bubba Watson, partner for Richard Mille since 2010, stands out from the crowd with his unique physique, personality and self taught skills in golf. Only 35 years old, he is already leaving his mark as one of the best players of his generation with one of the most powerful drives.

After the success of the limited RM 038 Golfer’s Tourbillon released in 2011, Richard Mille has undertaken the development of yet another specific tourbillon watch for Bubba Watson with added functionality to complement his powerful drives on the course: a patented G-sensor with a tourbillon mechanism.

The mechanical G-sensor, a Richard Mille world first containing more than 50 moving parts within a mere 17mm, allows the user to see the accumulated motion of their swing in G’s. The sensor, placed under 12 o’clock, is able to record the force generated by a golfer’s swing, specifically during the last segment. In reality this means that the RM 38-01 can record up to 20-G’s of acceleration, a very important insight for golfers such as Bubba Watson, renowned for his ability to hit a ball at more than 310 kilometers per hour. Resetting the sensor back to zero for the following swing is done by simply pressing the aerodynamically formed pusher at 9:00 once.

The G-sensor mechanism is integrated into the heart of a manual winding tourbillon movement with circa 48 hours of power reserve and equipped with skeletonized, asymmetrical flying bridges and plates machined from grade 5 titanium with PVD treatment.

The front and back bezels of the RM 38-01 are created in TZP-G, a ceramic class of material based on microscopic tubes of alumina oxide powder injected with green colorant at a pressure of 2,000 bars. This is followed by a long and difficult machining and grinding process with diamond tooling in order to obtain the exact complex curves and arcs typical of Richard Mille’s designs. In the last stage, the material is then delicately worked in order to create an attractive matt surface finish and further complemented with a central caseband in grade 5 titanium molded with white rubber, thus providing comfort and lightness for the user under all conditions.

The watch is released in an edition of 50 pieces worldwide.
