Richard Mille - RM 40-01 Automatic Winding Tourbillon McLaren Speedtail

To celebrate the release of the McLaren Speedtail, the Richard Mille RM 40-01 Automatic Winding Tourbillon McLaren Speedtail was designed to mirror the bold characteristics of the Speedtail and the philosophy behind it.

A limited edition of 106 watches, it was prioritised for McLaren Speedtail owners so they can match the number of their car and their watch. 

The design and execution of the watch demonstrate a holistic approach to conception of the movement, case and dial.

As a result, everything has been constructed according to extremely rigorous specifications. For example, a casing ring is no longer used, and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by titanium screws.

The bezel and caseback are made of grade 5 titanium whilst the caseband is made of Carbon TPT®. This is a remarkable material with a unique finish obtained by layering hundreds of sheets of carbon fibres using an automated process that changes the orientation of the weft between layers. Heated to 120 °C in an autoclave similar to those used for aeronautic components, the material is then ready to be machined at Richard Mille.
