What Is an Automatic Watch?
Understand automatic movements, power reserve and what to check before choosing your first mechanical watch.
By ODYSS Editorial
An automatic watch is a mechanical watch that winds its mainspring through the movement of your wrist. A moving weight inside the case, called a rotor, helps replenish the energy used to run the movement.
Automatic, mechanical and quartz: what changes?
Mechanical describes a movement powered by a mainspring. Automatic describes a mechanical movement with a self-winding system. A manually wound mechanical watch requires winding by hand. Quartz watches use a different regulating system, typically powered by a battery.
Why can an automatic watch stop?
The mainspring stores a limited amount of energy. Once that energy runs out, a watch left unworn can stop. This alone does not mean it is broken. Follow the instructions for the exact movement when restarting and setting it. Do not assume every automatic model can be wound manually.
What should you compare before buying?
- Movement information: look for the movement reference and model-specific operating instructions.
- Power reserve: compare the documented figure, rather than assuming all models run for the same duration.
- Fit: check case width, length and thickness as well as strap adjustment.
- Everyday use: check water-resistance guidance for the activities you have in mind.
Does automatic mean skeleton?
No. Automatic describes how the movement winds. Skeleton describes a design that reveals elements of the mechanism. An automatic watch can have an opaque dial, while a visible movement does not by itself establish automatic winding.
