The concept of speed finally materialised! The new GrandeVitesse Chronograph 24h features a double tachometer graduated in km/h as well as mph that can measure land speeds up to Mach 2. The sporty character of the line is underscored by the “non-skid” pattern of the crown, caseband and pushpieces. And let’s not forget the very emblematic large “12” associated with motor racing.
