Savoir-faire RM 40-01 Automatic Tourbillon McLaren Speedtail — RICHARD MILLE

Grade 5 titanium has been massively used for the CRMT4 calibre that drives the RM 40-01. It introduces the first in-house development for a power reserve display as well as the oversize date and function selector complications. All of which are firsts at Richard Mille on an in-house automatic tourbillon. See more at #RichardMille #RM4001 #automatic #tourbillon
