Richard Mille RM 056

The RM 056 is a manual-winding tourbillon movement developed by Richard Mille in collaboration with Renaud & Papi. It features a split-seconds chronograph complication and was housed in the brand's first fully transparent sapphire crystal case, which required over 1,000 hours of machining. The openworked design showcases the movement from every angle. Only five pieces were produced before discontinuation.
