In 2012, the RM 052 Tourbillon Skull, with its overtly philosophical allegory, served as a milestone in the history of Richard Mille. Symbolizing nonconformity and freedom, the watch was a runaway success, its only limit is that it had a very small production run. Demand for this esoteric piece encouraged Richard Mille to revisit the theme in a new way and bring to life the RM 52-06 Tourbillon Mask. Surrealistic, fantastic, mysterious. The curvaceous lines of the iconic symbol enthroned in the heart of the tourbillon movement make the RM 52-06 one of the most enigmatic calibres.
