An automatic watch that has stopped is not necessarily broken. When its energy is depleted, a few turns of the crown and a correct adjustment are generally enough to get it running again. The order of operations matters: you must first identify the functions of the crown, restart the movement, then set the time and calendar without forcing it.
Before you begin: identify the crown positions
The crown is the small button located on the side of the case. Depending on the watch, it can control manual winding, setting the date or day, and setting the time.
Not all watches use exactly the same positions. A simple watch may only have a winding position and a time-setting position. A model with a day and date may have an additional intermediate position. If the crown appears screwed down, do not pull on it immediately: consult the manual for your specific model.
How to restart a stopped automatic watch?
An automatic watch uses the movements of the wrist to maintain its energy. If it remains still for long enough, it will eventually stop.
Manual winding
When the model accepts manual winding:
- Remove the watch from your wrist.
- Leave the crown in its normal position.
- Turn it gently in the direction indicated by the manual.
- Perform about twenty steady turns to restart the movement.
- Stop if you feel any unusual resistance.
It is best to wind the watch while it is off your wrist. This avoids exerting lateral pressure on the crown stem. The product pages for the OCHSTIN Pilot Automatic GA62028A and the OCHSTIN Heritage Skeleton Automatic Watch both confirm that manual winding is possible.
Wrist movements
You can also move the watch gently to set its rotor in motion. A few smooth gestures can wake up the mechanism, but shaking the watch vigorously is neither necessary nor recommended. Wrist movement is primarily used to maintain energy while being worn. After a complete stop, manual winding is preferable when available.
How to set the time on an automatic watch?
- Gently pull the crown out to the time-setting position.
- Advance the hands in the direction indicated by the manual.
- Pass 12 o'clock once and observe the calendar.
- If the date changes, you have just passed midnight.
- Continue to the correct time, distinguishing between morning and afternoon.
- Push the crown back in completely.
This distinction is important on a watch with a date display. If you set 10 AM as if it were 10 PM, the date could change in the middle of the day.
Should you move the hands forward or backward?
Some movements allow the hands to be moved backward, but this operation can disrupt the calendar on other mechanisms. Without specific instructions for the movement, the safe method is to move the hands forward. Never force a crown that feels stuck.
How to set the date and day?
Watches equipped with a calendar often have a quick-set feature. Its exact position varies by model.
- First, move the hands to around 6 o'clock.
- Use the intermediate position of the crown to set the date.
- If the watch also displays the day, turn the crown in the corresponding direction.
- Return to the time-setting position.
- Advance the hands to the correct time.
- Push the crown back in completely.
Positioning the hands at 6 o'clock ensures you are away from the period during which the calendar mechanism is likely to be engaged.
The time range to avoid
As a precaution, avoid quick-setting the day or date when the watch displays a time close to midnight. A conservative rule is not to use this setting between 9 PM and 3 AM. The movement's manual remains the priority if it provides different hours.
According to its product page, the OCHSTIN Day-Date 40mm has a separate day and date display. On this type of model, you must distinguish noon from midnight before finalizing the adjustment.
Errors to avoid
| Situation | Recommended action | To avoid |
|---|---|---|
| Stopped watch | Gentle manual winding if available | Shaking it violently |
| Incorrect time | Identify midnight, then set the time | Forcing the crown |
| Incorrect date | Move hands to 6 o'clock | Quick-setting near midnight |
| Resistant crown | Stop and check its position | Using pliers or a tool |
Should you wind an automatic watch every day?
Not necessarily. When worn regularly, wrist movements normally maintain its operation. However, manual winding can be useful after several days of not being worn, after a complete stop, or before precisely setting the time and calendar.
A watch worn occasionally may stop between uses. This behavior is normal when its available energy has been exhausted.
Why does an automatic watch stop during the night?
It may not have accumulated enough energy, may have been worn very little, or may require inspection. Start by performing a correct manual winding if the model allows it. If it still stops quickly after being properly wound and worn, have the movement checked.
Be careful with water
The three OCHSTIN models mentioned in this guide are rated at 3 ATM on their product pages. This indicates resistance to splashes or rain, not permission for immersion. Also ensure that the crown is completely pushed back in after adjustment.
Frequently asked questions
How many turns does it take to wind an automatic watch?
About twenty gentle turns is a reasonable starting point after a stop. The exact number depends on the movement. Stop if you encounter unusual resistance.
Can you overwind an automatic watch?
Many automatic movements have a system to limit overwinding, but this never justifies forcing the crown.
In which direction should the watch be wound?
This depends on the movement. If the product page or manual does not specify, do not assume that one direction is suitable for all watches.
Why is my automatic watch running fast or slow?
A mechanical movement can exhibit a variation in timekeeping. Magnetism, shocks, resting position, and the state of the movement can influence it. A significant or sudden deviation warrants a check-up.
Is an automatic watch winder essential?
No. It can be convenient for a calendar watch worn on an alternating basis, but an automatic watch can be restarted and set manually.
Key takeaways
Wind the watch gently when it has stopped, identify midnight before setting the time, move the hands away from midnight before correcting the calendar, and never force the crown. To learn more, also consult our guide on how an automatic watch works and our tips for maintaining an automatic watch.
