LOUIS CHEVROLET
SWISS WATCHES

Version 1
October 2021

Congratulations and thank you for your purchase.
By choosing this watch you have entered the
Louis Chevrolet universe!
Being of Swiss origin and born just a few kilometers from our
factory, we had to honor Louis Chevrolet, the illustrious man who
made history.
From car mechanics to watchmaking precision, there was only
one step to take. The latter was all the easier because his father
was himself a talented watchmaker.
You are now one of the thousands of ambassadors of our brand!
Welcome to the Louis Chevrolet family
