RM 40-01 Tourbillon McLaren Speedtail

The RM 40-01 Tourbillon McLaren Speedtail is the most extreme watch ever made and the quickest road-going automobile McLaren has ever designed. Automatically winding tourbillon movement with function selector, large date, variable-geometry rotor, hours, and minutes.

Rob Melville, design director of McLaren Automotive, claims that the RM 40-01 is a spectacular illustration of why the two businesses are a perfect fit. Richard Mille watches are referred to as “race machines on the wrist,” and this is supported by the many similarities between our approaches to problem-solving, such as reducing resistance, vibrational effect, and weight.
