Watch Winder TPD Settings Database
Find the correct Turns Per Day (TPD) and winding direction for your watch. Verified for Aurawinder precision motors.
I / J
This database lists recommended turns-per-day (TPD) settings and winding directions for the movements collectors ask about most. Each entry gives a conservative working range rather than a single number, because individual examples of the same calibre vary with service history and age.
Last updated: November 2026. 29 calibre families, 19 brands. Free to cite with attribution — see the citation section at the foot of this page.
How to use this table
- Find your brand, then the calibre family. If you do not know your calibre, it is usually printed on the movement and listed in the watch’s documentation.
- Set your winder to the lower end of the TPD range first.
- Set the direction as listed. Run for 48 hours, then check whether the power reserve has increased. If it has not, switch to the opposite direction — or move up one TPD step.
If your calibre is not listed, start at 650 TPD bidirectional and run the same 48-hour test. That resolves almost every case.

| Sellita | SW500 (7750 architecture) | 800–1000 | Clockwise | |
| Miyota | 9015 | 650–800 | Bidirectional | |
| Miyota | 8215 / 8205 | 650–800 | Counter-clockwise | Unidirectional — verify before use |
Ranges are conservative starting points derived from manufacturer documentation and workshop practice, not absolute values. Where a manufacturer publishes a figure, that figure takes precedence. Verify with a 48-hour power-reserve test before relying on a setting long term.
Brand notes and further reading
Rolex
Rolex TPD settings and winder direction guide — per-reference detail, including the bidirectional question
Rolex reference-specific settings
Omega
Co-Axial movements are bidirectional and unusually tolerant of TPD variation. The 1861 in the Moonwatch is hand-wound and gains nothing from a winder.
Patek Philippe
Use conservative TPD. Why a winder can quietly damage a Patek
Seiko / Grand Seiko
Magic Lever winding is efficient and bidirectional; these winders rarely need high TPD.
ETA / Sellita / Valjoux
The 7750 family and its clones are the exception to the bidirectional rule — they wind clockwise only and need a higher TPD.
Why direction is the setting people get wrong
A bidirectional movement winds from rotor movement in either direction and is forgiving. A unidirectional movement winds from one direction only; rotate it the other way and the rotor freewheels, so the watch gains nothing while the motor runs. The 7750 family and the Miyota 8200 family are the two most common cases.
The test is simple and takes two days: set the listed direction, run 48 hours, check the power reserve. No gain means wrong direction.
Winders that let you set TPD and direction
A database is only useful if the winder lets you enter the numbers. These units offer per-rotor TPD and direction programming:
- Leather Watch Winder 2 Watches With LCD Screen Black
- Bamboo Quad Watch Winders – Bamboo for Men — independent setting per rotor
- Maselex Single Black Leather Shell Watch Winder with Gray Flannelet Interior

Method and sources
- Where a manufacturer publishes a TPD or direction figure, that figure is used in preference to any third-party value.
- Where no official figure exists, the range given is the conservative intersection of published workshop practice and observed power-reserve behaviour.
- Ranges are deliberately wider than single-number claims, because service history, mainspring condition and lubrication age all shift the practical figure for an individual watch.
- Every setting here is intended as a starting point for a 48-hour verification test, not as a substitute for a watchmaker’s assessment.
Changelog
- November 2026 — initial published version: 29 calibre families across 19 brands; added explicit citation and method sections.
Frequently asked questions
What does TPD mean on a watch winder?
Turns per day — the number of complete rotations the winder makes in 24 hours. It is a setting, not a quality rating. The correct value depends on your movement, not on the winder.
Is a higher TPD better?
No. Excess rotation keeps the mainspring at full tension and the slipping bridle working constantly, which adds wear without adding power.
What happens if I use the wrong direction?
On a bidirectional movement, nothing — it winds either way. On a unidirectional movement, the watch gains no power even though the winder is running.
How do I know if my setting is right?
Run 48 hours and check the power reserve. If it has increased, the setting works. If not, change direction first, then raise TPD one step.
Do manual-wind watches go on a winder?
No. Hand-wound movements are not wound by motion, so a winder does nothing for them.
Can I damage a watch with the wrong TPD?
Overwinding is prevented by the slipping bridle, so catastrophic damage is unlikely. The realistic risk is accelerated wear from a setting far above what the movement needs.
