What is an automatic watch?
An automatic watch works without a battery: it recharges itself thanks to the movements of your wrist. As long as you wear it every day, it continues to work. If you leave it unused for more than 42 hours, it simply stops and starts again as soon as you put it back on or by slightly turning the crown.
This type of mechanism, derived from traditional watchmaking know-how, is more complex and refined than a classic quartz mechanism (battery).
A portion of every order is donated to youth education programs to help build a brighter future, one watch at a time.
