RM 008-V2 Manual Winding Tourbillon Split-Seconds Chronograph.

A superlative chronograph, the RM 008-V2 pairs a tourbillon with a split-seconds mechanism and was the first new split-seconds chronograph design of the 21th century.
Since its creation in 2003, the RM 008-V2 continues to warrant its claim as one of the most complicated watches in the collection.
The RM 008 incorporates all the characteristics of the RM 004 split-seconds chronograph, to which we added a tourbillon carriage comprising 85 parts and weighing just a third of a gram (0.34 g). Assembly and adjustment of this component alone requires several months to complete.
These two complex features demand advanced technical prowess.
