Automatic vs. Quartz Watches: What's the Difference?

Every watch is powered by one of two kinds of movement: automatic or quartz. Here's the difference, and how to choose.

Quartz: simple and accurate

  • Runs on a small battery that usually lasts 1–3 years.
  • Very accurate and needs almost no attention.
  • The seconds hand ticks once per second.
  • Usually lighter and less expensive.

Automatic: mechanical and alive

  • No battery. A weighted rotor winds the watch as your wrist moves.
  • The seconds hand sweeps smoothly instead of ticking.
  • Skeleton and open-heart dials let you watch the gears work.
  • It may stop if you don't wear it for a day or two. A few turns of the crown start it again.
  • Accuracy is within a few seconds a day, which is normal for a mechanical watch.

Which should you choose?

  • Choose quartz if you want grab-and-go, set-and-forget simplicity.
  • Choose automatic if you love craftsmanship and want a watch people ask about.
