My Rotor Rolls on Rotating Rubies: Yeah! One of the most sophisticated and interesting early automatic calibers -- the Vacheron Constantin caliber K1072. With solid-gold rotor-weight, Geneva-seal-marked and the rotor rolling on rotating rubies. All this cased in the super-rare whitegold case (Casemaker Key[10]: Robert Meylan?) and under a beautiful patinaed linen-dial. Important & Beautiful Rotary Club.
