How to Wind a Pocket Watch (With or Without a Key)
Nov 7, 2026 · The Editors
How to wind a pocket watch correctly: stem-wind and key-wind watches, how many turns, how to avoid overwinding, setting the time with the crown or the lever, how often to wind — and when a watch needs no winding at all.
A mechanical pocket watch runs on a coiled spring — the mainspring — which slowly unwinds to drive the hands. Winding it is a small daily ritual, and doing it right keeps the watch healthy for decades.
First: does it need winding?
Many modern pocket watches are quartz, powered by a battery. They never need winding: the crown only sets the time. If your watch ticks once a second, has a battery hatch, or says "quartz" on the dial or back, skip to "setting the time" below.
How to wind a stem-wind pocket watch
Most pocket watches from the 1870s onward are stem-wind: you wind them with the crown.
- Hold the watch in one hand, crown up.
- Turn the crown clockwise (away from you) with your thumb and forefinger. Many watches make a gentle clicking sound.
- Count the turns. A fully run-down watch usually takes about 20 to 40 half-turns — it varies by watch.
- Stop when you feel resistance. The crown becomes firm and will not turn further easily. Do not force it.
Turning the crown backwards on most watches does nothing, or simply clicks — it will not harm it.
How to wind a pocket watch with a key
Older watches, before about 1880, are key-wind:
- Open the back of the case (and sometimes an inner dust cover).
- Find the winding arbor — a small square post.
- Fit the key and turn it in the direction it moves freely, until you feel resistance.
- To set the time, many key-wind watches have a second arbor on the dial side, under the front crystal.
Keep the key with the watch; a key that does not fit properly can round off the arbor.
How to wind without a key
If a key-wind watch has lost its key, replacement keys come in numbered sizes — take the watch to a watchmaker, or buy a set of keys and try them gently. Never use pliers.
Setting the time
- Pendant set: pull the crown out one click and turn it to move the hands. Push it back in.
- Lever set (common on railroad watches): open the front crystal or bezel, pull out the small lever at the edge of the dial, then turn the crown. Push the lever back before closing.
Always move the hands forward where possible.
How often to wind
Once a day, at the same time — most people choose the morning. A full wind usually lasts about 30 to 40 hours, so daily winding keeps the spring in its best range and the watch at its most accurate.
Can you overwind a pocket watch?
You cannot overwind a healthy watch by winding it normally — the spring simply reaches full and stops. "Overwinding" usually means forcing the crown past the point of resistance, which can break the mainspring. A watch that stops while fully wound is not overwound: it needs servicing.
Looking after it
- Service a mechanical watch every few years.
- Keep it away from magnets — phone speakers, laptop lids.
- Store it face up, in a pouch or a box.
No winding at all
If you love the look but not the ritual, a quartz pocket watch gives you the chain, the cover and the Roman numerals, and keeps time without winding. Hunter vs open face · How to wear a pocket watch.
