Automatic, manual-wind mechanical, or quartz watch: what are the differences?

All watches display the time, but not in the same way. Understanding your watch's movement means knowing how to wear, maintain, and store it.

Quartz watch

A battery powers a quartz crystal that vibrates at a very stable frequency. The result: great accuracy and almost no maintenance, except for an occasional battery change. It does not need to be wound: a watch box or a case is enough to store it.

Manual-wind mechanical watch

This is the most traditional form of watchmaking. The spring is wound by turning the crown, generally every day or every two days depending on the power reserve. This daily ritual is part of its charm. A watch winder is useless for these watches: only the owner's gesture winds them.

Automatic watch

An automatic watch is a mechanical watch equipped with a rotor, an oscillating mass that turns with the movements of the wrist and winds the spring. Worn regularly, it works without intervention. Left motionless, it stops at the end of its power reserve, often between one and three days.

How to recognize them?

• The second hand: on a quartz watch, it advances in one-second jumps; on a mechanical one, it glides smoothly.
• The transparent back: if it reveals a half-moon mass, the watch is automatic.
• The mention on the dial: "Automatic", "Quartz" or nothing at all for many manual mechanical watches.

What case for which movement?

• Quartz and manual-wind: a box, a display case or a case.
• Automatic worn every day: a box is enough.
• Several automatics worn alternately: a winder.
