What is an automatic watch?
An automatic watch doesn’t rely on a battery. It is powered by the natural motion of your wrist, which keeps the movement wound as you wear it. With regular use, it runs continuously. If left unworn for over 42 hours, it may stop, but it will start again once you put it back on or gently wind the crown.
Rooted in traditional watchmaking craftsmanship, this type of movement is more intricate and sophisticated than a standard quartz (battery-powered) mechanism.
