"Precision, elegance, excellence…This is the very essence of Zenith and of the Tour Auto Optic 2ooo. In 2015, the brand become the watch partner of the oldest motor race still running today. Revived in 1992 by Peter Auto, the 24th annual event will taken place between the 21st and 25th April 2015, supported by Zenith. This unmissable event in the classic car enthusiast's calendar, which brings together 225 vintage models, sets the watch brand on an adventurous course which reaffirms its values: pleasure, daring and authenticity."

Would love it if they post some pictures of those old chariots!
