In 2011, Richard Mille undertook the challenge of creating a watch for golfers and, working with the PGA Tour player and double Masters winning golfer Bubba Watson, created the RM 038, specifically designed to withstand the incredible g-force generated when a club is swung to propel a golf ball at nearly 200 mph. From its crystal and case to its movement and strap, every single detail of the watch is engineered to minimise weight, ensure comfort and reliability, all necessary for professional sportsmen.

In 2012, Richard Mille decided to make improvements on its original design and created the RM 055. The present model is also distinguished by its diamond-set bezel. The mechanical movement that powers this watch is made from grade 5 titanium displays extreme skeletonisation, with a PVD- and Titalyt-treated baseplate and bridges.

This combination confers great rigidity on the whole assembly, as well as the precise surface flatness essential for perfect functioning of the gear train. The skeletonised baseplate and bridges were subjected to intensive and complete validation tests to optimise their resistance capacities. The Calibre RMUL2 is thus capable of withstanding accelerations of over 5000 g’s. A key focus of the Richard Mille manufacture, it has been optimized in order to weigh approximately a mere 4.3 grams.
