After partnering with Audemars Piguet for several years and after the release of two Royal Oak Offshore limited editions, the legendary Paris-Biarritz race Tour Auto Optic 2000 is now partnering with Zenith. They will finally come together on the starting line of the 24th Tour Auto. Zenith will be the official timekeeper of the competition, and three connoisseurs of mechanical beauty and speed will set off, along with their co-drivers, under its banner. On their wrists, the new Zenith El Primero Chronomaster 1969 Tour Auto Edition, a sporty model specially designed for the event in a limited edition of 500 pieces. This new watch, crystallizes the spirit of its partnership with the Tour Auto. Haute Horlogerie and collector's cars are linked by fastidious expertise, as well as a desire for perfection and elegance. The new Zenith El Primero Chronomaster 1969 Tour Auto Edition joins them forever by combining the revolutionary chronograph movements for which the Le Locle Manufacture has become famous, with a design whose finely nuanced colors and symbolic elements reveal a subtle automotive influence.
