Collectors prioritize this reference for its technical construction, featuring a tripartite case milled entirely from solid blocks of synthetic sapphire, a process requiring over 1,000 hours of machining per watch. It houses the manual-winding Caliber RMCC1, a split-seconds tourbillon movement with power reserve and torque indicators. Due to its extreme rarity and status as the brand’s first full-sapphire model, secondary market prices typically range from $3,000,000 to $5,000,000 depending on provenance. A notable production evolution followed in 2013 with the RM 56-01, which incorporated sapphire baseplates and bridges, further reducing the use of titanium in the movement architecture.", "score": 200}]}
