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).
With every watch purchased, you help support meaningful charitable initiatives turning a simple choice into a positive impact that goes beyond timekeeping.
