The brand’s most famous models are the Tourbillon RM 008 (chronograph tourbillon) and the sapphire split seconds (chronograph tourbillon) RM 056. The RM 008 combines a tourbillon movement with manual winding, a chronograph split-seconds, a torque indicator, and a power reserve indicator. Claimed to be one of the most advanced watches in the world, it is priced from €500,000.

The RM 056 split seconds (chronograph tourbillon) is distinguished by its three-part all-sapphire skeletal case. The RM 056 is completely see-through and is the first watch case to be completely built from sapphire, with a limited edition five pieces of the Richard Mille RM 056 Felipe Massa Sapphire priced at US$1.7 million. The RM 056 was declared best watch of 2012 at the Salon Internacional de Alta Relojería watchmakers’ exhibition in Mexico City in October 2012.
