LIKE NEW RICHARD MILLE 18K WHITE GOLD DIAMOND ULTRA-FLAT / RM16

This exclusive RICHARD MILLE design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level whether it be sporting or non-sporting environments. By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or slow it down when sporting activities are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized and personalized to the owner’s lifestyle. Case size 38mm by 50mm. With Box & Cert Dated March 2013.Retail Price $161300. Can pass off as new.
