BBR, a factory that specilized in making replicas with tourbillon movement, now is very liking manufacturing Richard Mille replica watches. They have made several top quality replicas of Richard Mille, including RM035-01 and RM035-02, they believe that they can beat ZF and Sonic, but for the highest quality replicas of Richard Mille RM35, I still suggest people buy from Sonic. Well, for this RM055, it is a great updated V3 edition, with two barrels and a working balance wheel which you can notice from its skeleton dial on the front. Some factory has really made great efforts to create such a beautiful movement on RM, the case thickness of the replica is only 13.5mm.
