Turns per day and winder settings
What turns per day means, which direction to choose, and the figures commonly published by brand.
A watch winder has three settings that matter: how many turns it makes in twenty-four hours, which way it turns, and how long it rests between bursts. Set those three correctly and the watch behaves exactly as it would on a wrist that is worn every day.
Turns per day
Turns per day, usually written TPD, is the number of complete rotations the cradle makes in a day. It is not a speed. A winder set to 800 TPD does not spin continuously; it turns for a few minutes, rests, and turns again, so that the total across the day comes to 800.
Almost every modern automatic sits somewhere between 650 and 900 TPD. Set it too low and the watch runs down and stops. Set it too high and, on any movement with a slipping mainspring clutch — which is essentially all of them since the 1950s — the excess winding is absorbed rather than transmitted. The practical risk of over-winding a modern automatic on a winder is very small; the practical annoyance of under-winding is a watch that has stopped when you want to wear it.
Direction
Some movements wind in one direction only, some in both. A bi-directional setting alternates, which covers either case, and it is the setting to choose when you cannot find a figure for your calibre. A unidirectional setting on a movement that winds the other way does nothing at all.
Rest
The rest period is what makes a winder gentle. A good programme turns for two to five minutes and then stops for the remainder of the hour, which is closer to a day of wear than continuous rotation would be. Programmes that never stop are the ones worth avoiding.
Settings by brand
Read this before using the table. These are the figures commonly published by retailers and long-standing collector references. We have not confirmed a single one against manufacturer documentation, and they are marked accordingly. Use them as a starting point, then set the winder to whatever your own calibre’s manual states. Where a brand publishes nothing, 800 TPD bi-directional is the usual safe choice.

[NEEDED — Jesse] Before this store is opened to search engines, these figures should be checked against manufacturer documentation, or the table replaced with a shorter one covering only the brands we can source properly. A table of unverified numbers on a page that ranks is a liability.
Checking the setting worked
- Wind the watch by hand to a full wind, or wear it for a full day, before it goes on the rotor.
- Set the time against a reference — your phone will do.
- Leave the watch on the winder for forty-eight hours without touching it.
- Compare it with the reference again. If the watch has stopped, or lost badly, raise the turns per day by one step. If it is keeping normal time for the calibre, the setting is right.
Things worth knowing
- Do not turn the rotor by hand. Stopping or spinning a cradle while the motor is driving it is one of the few ways to actually damage the mechanism.
- Keep the watch away from magnets. Winders are not magnetic, but the speakers, phone stands and closures that end up on the same dresser are.
- Secure the watch on the cushion. A loose watch on a turning cradle will eventually work its way off.
- A winder is not a service. It keeps oil distributed rather than settled, which is worth something, but the service interval is set by the manufacturer and does not move because the watch has been on a rotor.
