Winders and boxes

A watch winder keeps an automatic running while you are not wearing it. It is a convenience, not a necessity: letting a simple automatic stop and setting it again does no harm.

Common TPD settings
about 650, 800 or 950 turns per day
Direction
clockwise, counterclockwise or both, by movement

A winder turns the watch for a while and then rests, repeating through the day. The turns per day (TPD) and the direction should match the movement: most need roughly 650 to 950 TPD, and many wind in both directions. Makers and winder brands publish the figure for common movements, so check it before you set the winder.

A winder is most useful for watches that are slow to reset, such as a perpetual calendar, a moon phase or a day and date you set often. A modern automatic cannot be overwound by a winder: a slipping spring in the barrel stops the mainspring from winding further.

For storage, a box with soft cushions and a lid keeps dust and scratches off. Keep watches away from strong magnets such as speakers and phone cases with magnetic closures, which can make a movement run fast.

Common mistakes

  • Running a winder far above the TPD the movement needs.
  • Placing a winder or box next to a speaker or another strong magnet.
  • Buying a winder for a simple automatic you wear most days.
