TPD — Turns Per Day — is the single most important setting on any watch winder. Get it right and your watch stays perfectly wound, accurate, and ready to wear. Get it wrong and your watch may stop, run inaccurately, or simply not wind at all. In this complete guide, Aevitas UK explains exactly what TPD means, why it matters, and provides a comprehensive reference for every major watch brand. You can also use our interactive TPD settings database to look up the exact settings for your specific watch model.
What is TPD (Turns Per Day)?
TPD stands for Turns Per Day — the number of rotations a watch winder makes in a 24-hour period to keep an automatic watch's mainspring fully wound. Every automatic movement has a minimum TPD requirement set by the manufacturer, based on the efficiency of the rotor and the capacity of the mainspring.
If the TPD is too low, the watch will not receive enough winding energy and will eventually stop. If the TPD is higher than needed, the slip-clutch mechanism simply disengages — there is no risk of over-winding with a quality winder. For a full searchable list of TPD requirements by watch model, visit our TPD settings database.
What is Rotation Direction?
Alongside TPD, rotation direction is the second critical setting. Automatic movements wind in one of three ways:
- Clockwise (CW) — The rotor only winds when rotating clockwise
- Counter-clockwise (CCW) — The rotor only winds when rotating counter-clockwise
- Bi-directional (CW+CCW) — The rotor winds in both directions, which is the most common configuration in modern movements
Setting the wrong direction won't damage your watch, but it will fail to wind it efficiently. Always match the direction to your specific movement. Not sure which direction your watch uses? Check our watch winder settings database for your exact model.
All Aevitas winders — from the single carbon fibre winder to the 8 watch winder — offer clockwise, counter-clockwise, and bi-directional rotation with five TPD settings: 650, 750, 850, 1,000 and 1,950 turns per day.
TPD Settings by Watch Brand: The Complete Reference
The figures below are general guidelines for each brand. For model-specific settings, use our full TPD database.
Rolex
- Recommended TPD: 650–800
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 650 or 750 TPD, bi-directional
- Notes: Rolex recommends a minimum of 650 TPD. The Perpetual rotor is among the most efficient in the industry. Find your Rolex model settings here.
Omega
- Recommended TPD: 650–800
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 650 or 750 TPD, bi-directional
- Notes: Omega Co-Axial and Master Chronometer movements are highly efficient. Find your Omega model settings here.
Breitling
- Recommended TPD: 650–1,000
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 750 or 850 TPD, bi-directional
- Notes: COSC-certified chronograph movements benefit from a slightly higher TPD. Find your Breitling model settings here.
TAG Heuer
- Recommended TPD: 650–900
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 750 or 850 TPD, bi-directional
- Notes: 850 TPD is a reliable setting for most TAG Heuer calibres. Find your TAG Heuer model settings here.
IWC
- Recommended TPD: 650–900
- Direction: Clockwise only (CW)
- Aevitas setting: 750 or 850 TPD, clockwise
- Notes: IWC is one of the few major brands using a predominantly clockwise-winding rotor — critical to set correctly. Find your IWC model settings here.
Tudor
- Recommended TPD: 650–800
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 650 or 750 TPD, bi-directional
- Notes: Tudor in-house movements share similar winding characteristics to Rolex. Find your Tudor model settings here.
Patek Philippe
- Recommended TPD: 650–800
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 650 or 750 TPD, bi-directional
- Notes: For perpetual calendar models, continuous winding is strongly recommended to avoid complex resetting. Find your Patek Philippe model settings here.
Hublot
- Recommended TPD: 650–1,000
- Direction: Bi-directional (CW+CCW)
- Aevitas setting: 850 or 1,000 TPD, bi-directional
- Notes: The UNICO in-house calibre benefits from a slightly higher TPD. Find your Hublot model settings here.

How to Set Your Aevitas Watch Winder
- Look up your watch's recommended TPD and direction in our TPD database or your watch manual
- Select the nearest TPD setting on your winder: 650, 750, 850, 1,000 or 1,950
- Set the rotation direction to match your movement (CW, CCW, or bi-directional)
- Place your watch on the spring-loaded holder and secure it
- Connect to mains power and allow 24 hours for the watch to reach full wind
For multi-watch winders, each position has independent controls — allowing different TPD and direction settings per watch simultaneously.
What if My Watch Keeps Stopping?
- Increase the TPD setting by one step (e.g. from 650 to 750)
- Check the rotation direction — switch to bi-directional if currently set to one direction only
- Ensure the watch is correctly seated on the holder and rotating freely
- Manually wind the watch fully before replacing it — a fully depleted mainspring may need a head start
- Cross-reference your model in our TPD database to confirm the correct settings
Frequently Asked Questions
Can I use a higher TPD than recommended?
Yes. The slip-clutch mechanism prevents over-winding regardless of TPD. A higher setting simply means the winder works slightly harder than necessary.
What TPD should I use if I don't know my watch's requirements?
900 TPD bi-directional is a safe universal starting point. Alternatively, look up your exact model in our TPD settings database.
Does TPD affect the winder's motor life?
Minimally. Aevitas brushless German motors are rated for decades of continuous operation at any TPD setting.
My watch has a 7-day power reserve. Does it need a winder?
A long power reserve means your watch runs for 7 days unworn — but if you rotate between watches, a winder still ensures it's always fully wound and ready.
