In short: Take the watch off, unscrew the crown anti-clockwise and, if it has stopped, wind about 25 to 30 turns clockwise. Never quick-set the date between 9pm and 3am: move the hands to around 6 o’clock, set yesterday’s date, then advance the hands forwards past midnight to the correct time and screw the crown fully down.
More mechanical watches are damaged by careless setting than by accidents. The movements inside a Rolex are robust, but a few habits — setting the date at the wrong hour, forcing the crown, over-winding by hand — cause avoidable and expensive repairs. Here is the correct routine, in order.
Unscrewing the crown
Rolex Oyster cases use a screw-down crown. Turn it anti-clockwise until it releases and springs out — never pull first. Support the watch in your hand rather than operating it on the wrist: setting on-wrist forces the crown at an angle and is the leading cause of bent stems.
How do you wind a Rolex that has stopped?
With the crown unscrewed at its first position, turn it clockwise about 25–30 times. Modern Rolex movements have a slipping clutch on the mainspring, so you cannot over-wind them — but do not spin the crown aggressively either. An automatic worn daily needs no hand-winding; it winds itself.
Why should you never set the date between 9pm and 3am?
This is the single most important rule. During those hours the movement’s date-change gears are engaged, and forcing a quick-set date while they are meshed can break teeth — a costly repair. Set the time to around 6 o’clock first, then set the date safely, then set the correct time.
How do you set the time and date on a Rolex?
- Unscrew the crown (anti-clockwise) and let it spring out.
- If stopped, wind ~25–30 turns clockwise.
- Pull to the middle position and move the hands to roughly 6 o’clock.
- Quick-set the date to yesterday’s date.
- Return to the time position and advance the hands forwards past midnight — when the date flips, you know you are in AM.
- Continue forwards to the correct time (past noon if it is afternoon).
- Push the crown in and screw it fully down clockwise.
Always move the hands forwards. Winding backwards past midnight puts unnecessary stress on the date mechanism.
On watch winders
A winder is convenient for calendar watches you wear occasionally, but it is not necessary — and constant unnecessary rotation adds wear. For most owners, letting a watch stop and setting it when needed is perfectly fine and gentler on the movement.
Setting checklist
- Take the watch off; never set it on the wrist.
- Unscrew anti-clockwise; never force or pull first.
- Never quick-set the date between 9pm and 3am.
- Set hands to ~6 o’clock, then date, then time.
- Always advance hands forwards, past midnight to confirm AM.
- Screw the crown fully down before wearing — especially near water.
Rolex stopped or running fast? What it usually means
Most timekeeping worries have a simple explanation. For its Superlative Chronometer certification, Rolex specifies -2/+2 seconds a day on current models. Older references were certified to a looser standard, and any watch drifts as a service falls due, but a sudden change or an unexpected stop is worth checking.
| Symptom | Likely cause | What to do |
|---|---|---|
| Stopped after a few days off the wrist | Nothing is wrong: the power reserve has run down. It lasts about 48 hours on older calibres such as the 3135 and about 70 hours on current ones such as the 3235. | Wind and set it using the sequence above. |
| Stops even when worn daily | The winding system is not keeping up, or a service is due. | Have the automatic winding checked. |
| Suddenly gaining tens of seconds or minutes a day | Most often magnetism from phones, laptops, speakers or magnetic bag clasps. | Have it checked for magnetism and demagnetised if needed. |
| Losing time or running erratically | The movement needs regulation or a service. | Have the rate measured before any work is agreed. |
| Crown will not screw down or feels gritty | Wear on the crown tube or its threads. | Do not force it. Keep it out of water until it is inspected. |
| Fog or droplets under the crystal | Water has got inside the case. | Bring it in the same day. Do not try to dry it out yourself. |
If winding does not solve it, or you see any of the other signs above, bring the watch to our independent workshop in Athens for a free written diagnosis and quote before any work is done. For background, read how often to service your Rolex and Rolex water resistance explained.

Frequently Asked Questions
Can I over-wind a modern Rolex?
No. A slipping clutch on the mainspring prevents over-winding on modern automatics. Still, wind smoothly rather than forcing the crown.
Why can’t I set the date at night?
Between roughly 9pm and 3am the date-change mechanism is engaged. Forcing a quick-set then can damage the gear teeth — an expensive repair for a moment’s convenience.
How many turns to wind a stopped Rolex?
Around 25–30 clockwise turns with the crown in its first position is enough to start it reliably; wearing it will keep it wound.
Can you wind a Rolex backwards?
Turning the crown backwards does no harm, but it does not wind the watch either: a Rolex winds in one direction only, and the other way the crown simply turns freely. Unscrew the crown, then turn it clockwise to wind.
Do I need a watch winder?
Not really. It is convenient for calendar watches worn occasionally, but unnecessary rotation adds wear. Letting a watch stop harms nothing.
