How to tell if a watch is automatic or quartz

Watch the seconds hand. On a quartz watch it jumps once per second. On a mechanical watch, automatic or hand-wound, it sweeps in several small steps per second and looks almost smooth.

Other signs without opening the case

• Dial text. "Automatic", "Self-winding" or a jewel count points to mechanical. "Quartz" is often printed outright.
• Caseback. A glass back showing a swinging half-disc, the rotor, means automatic. No rotor and visible gears means hand-wound.
• Sound and feel. Mechanical watches tick rapidly. An automatic's rotor can be felt turning when you move the watch.
• Behaviour. A mechanical watch stops a day or two after you take it off. A quartz watch runs until the battery dies.

Exceptions worth knowing

Watches with no seconds hand hide the easiest clue. Some hybrid movements pair a quartz base with a sweeping chronograph hand, and a few high-end electronic movements glide smoothly. When the signs conflict, the reference number settles it, because each reference is built with a specific caliber.

Why it matters

Movement type affects value, servicing and care. A mechanical watch needs a periodic service. A quartz watch left with a dead battery can leak and damage the movement.
