The OW Rallychron is a love letter to the golden era of motor racing and the legendary circuits that bore witness to the most memorable moments in the sport’s history. One of the defining features of this era was the sheer diversity of racing circuits and the challenges they presented. From the fast and flowing tracks like Monza and Spa-Francorchamps to the tight and twisty streets of Monaco, each circuit demanded different skills from drivers and teams. The bezel of the Rallychron features hypothetical historic ‘perfect lap’ times for 11 of the world’s most iconic race tracks. It also bares the characteristics of Ollech & Wajs classic competition chronographs and rally timers from the 60s and 70s.
