It was the first split seconds Tourbillon chronograph from Richard Mille and a tour de force APRP movement
This is an RM008-v1 in sand blasted Ti
Back in the day I owned an RM004 that had the same exact finish only difference is no Tourbillon on mine but never the less an amazing if not the best RM through and through
For me the RM008 stands out from the slew of more “modern” iterations or evolution of the caliber which houses the same complication ascending from the 008
Now the RM50 family takes on that mantle and continues so with different iterations 50,50-1,50-2,50-3 , ACJ, JTD and the 56-01
