# How to use a watch winder Source: https://lumeandbezel.com/blog/how-to-use-a-watch-winder Published: 2026-10-09 Publisher: Lume & Bezel **Short answer:** Wind the watch by hand or wear it first so it starts with a good charge, set the time, then fit it snugly on the cuff. Set the winder to the turns per day (TPD) and direction your watch maker recommends, or start in the middle of the range in bidirectional mode. After 24 hours, check that the watch is still running and on time, and adjust TPD if it has stopped. A watch winder is simple to run, but a few setup steps make the difference between a watch that keeps time and one found stopped a day later. This page explains how a winder works, then walks through pre-winding, fitting the cuff, choosing turns per day and direction, and checking the result. It is for new winder owners and anyone whose watch is not staying wound on a winder. If you are still deciding whether to buy one, read [do you need a watch winder](https://lumeandbezel.com/blog/do-you-need-a-watch-winder) first. ## How a watch winder works An automatic watch winds itself through a weighted rotor that swings when the watch moves. A winder holds the watch on a cuff and turns it slowly, which swings the rotor and winds the mainspring, just as wearing it would. Most winders run in cycles: they turn for a while, then rest, and repeat through the day. Two settings control how much winding the watch gets. **Turns per day (TPD)** is how many full rotations the winder makes in 24 hours. **Direction** is clockwise, counterclockwise or both, because some movements wind with the rotor turning one way only. Winder listings show the range they offer; Wolf modules list 300 to 1200 TPD, while Rothwell and Dukwin winders list presets of 650, 750, 850, 1000 and 1950 TPD. ## How to set up a watch winder step by step 1. **Place the winder.** Put it on a stable, level surface away from strong magnets and direct sunlight. Plug it in, or fit batteries if it runs on them; some Heiden models take two D cells or an AC adapter. 2. **Pre-wind the watch.** If the watch has stopped, wind it by hand with the crown, if the movement allows, or wear it for a few hours. A winder is designed to maintain a charge, not to fill an empty spring quickly. 3. **Set the time and date.** Do this before you mount the watch so you do not have to take it off again. 4. **Fit the cuff.** Close the bracelet or strap around the cuff so the watch is snug and does not slide. Many cuffs compress; squeeze, slide the watch on, and let it expand. 5. **Choose TPD and direction.** Use your watch maker's recommendation if you can find it. If not, start in bidirectional mode at a middle setting, such as 650 to 900 on a typical range. 6. **Close the lid and start it.** Some winders, such as models with an open-stop sensor, pause when the lid opens. 7. **Check after 24 hours.** Confirm the watch is running and on time. If it has stopped or is losing reserve, raise the TPD one step or switch direction. Note: Keep the watch's crown pushed in or screwed down on the winder. A crown left in the winding or setting position can stop the watch or let dust in. ## Choosing turns per day and direction The right TPD depends on the movement: how efficient its rotor is and how much energy it uses. Watch brands and winder makers publish recommended settings for many calibers, and that is the best starting point. Our page on [watch winder TPD settings](https://lumeandbezel.com/blog/watch-winder-tpd-settings) explains how to find and use them. Direction matters because some rotors wind in only one direction. If a watch keeps stopping in clockwise mode, try counterclockwise. Bidirectional mode works for any movement, which is why it is the safe default. On Wolf winders, the listing notes that bidirectional mode doubles the effective TPD, so you may need a lower base setting. | Situation | What to try | | --- | --- | | Unknown movement | Bidirectional, middle of the TPD range | | Watch stops after a day or two | Raise TPD one step, or try the other direction | | Watch keeps running well | Leave it, or try one step lower | | Several watches on one winder | Set each position separately if the winder allows | Starting points when no maker guidance is available ## How long to run a watch winder Most owners leave a winder running all the time with the watch on it. Winders are designed for continuous use and spread their turns through the day with rests. The watch then runs as if you wore it daily, so it is ready to put on at any time. You do not need to run a winder for a set number of hours to charge a watch, as you would a phone. If you only want a watch ready for a specific day, wearing it or hand winding is quicker. If you are going away for weeks and do not need the watch, it is fine to let it stop; nothing is harmed.

Our page on [watch winder not turning](https://lumeandbezel.com/blog/watch-winder-not-turning) covers more. - **Watch slips on the cuff:** tighten the bracelet a link or use a larger cuff if available.

Winders are built to run continuously with rest cycles, so you can leave a watch on one indefinitely. **Do I need to wind the watch before putting it on a winder?** Yes, it helps. A winder maintains a charge. Starting with a stopped watch can take a long time to build enough reserve, so wind or wear it first. **What TPD should I use?** Use your watch maker's recommendation. Without one, start bidirectional at a middle setting and adjust after a day. See [watch winder TPD settings](https://lumeandbezel.com/blog/watch-winder-tpd-settings). **Can a watch winder overwind my watch?** No. Automatic mainsprings have a slipping clutch, so extra turns do not overwind the spring. ## Gear guides for this topic - https://lumeandbezel.com/best/best-watch-winders - https://lumeandbezel.com/best/best-single-watch-winders - https://lumeandbezel.com/best/best-watch-winders-for-luxury-watches
