Why an automatic watch is slow: common causes
When you automatic clock goes backwards, is often due to a number of technical and usage factors:
- Low power reserve: if the watch has not been used continuously, it may have stopped or run below its optimal power.
- Shock or thermal exposure: drops and temperature extremes can throw the flywheel out of adjustment and affect accuracy.
- Dirt or lack of lubrication: Internal particles can slow down the gear train, causing delays.
- Magnetisation: magnetic fields can misalign the spiral and disrupt the rhythm.
Initial steps when your automatic clock is slowing down
- Intensive manual loading: turn the crown 20 to 30 times to fill the mainspring completely.
- Check the rest position: leaves the watch crown up, crown down or dial down and measures its performance in each position.
- Avoids shocks and magnetism: keep it away from electrical appliances or magnetic devices.
Professional adjustment: adjustment of the regulating handwheel
If after recharging and resting the automatic clock keeps running backwards, you will probably need to mechanical control. This involves precisely moving a small lever within the regulating balance system (racket). This fine adjustment should be done by a qualified watchmaker.
When to call for service
- Constant loss of 10-20 seconds per day
- Longer delays after full load
- Obvious magnetisation or strong shocks
- More than 4-5 years since last maintenance
In such cases, be sure to call in a specialised technician:
- Perform demagnetisation.
- Clean and lubricate the movement.
- Adjust the pace of the steering wheel with chronocomparator if necessary.
Key tips for maintaining the accuracy of your automatic watch
- Carry it regularly or use a reel to maintain a constant load.
- Avoid contact with magnets and sudden changes in temperature.
- Manual charging from time to time, even if it is automatic.
- Service schedule every 4-5 years.
FAQ: automatic watches that go backwards
How many seconds a day can a good automatic watch be set back?
A well-adjusted clock can be set back 5 to 10 seconds per day; larger deviations indicate a need for service.
What is the power reserve?
It is the time that a automatic clock is late or stops working when not in use. At least one full charge guarantees sufficient power.
Can I regulate it myself?
Adjustment is complex: it requires moving the steering wheel racket without damaging the spiral. It is much safer to go to a professional watchmaker .
Does it stop if it is demagnetised?
If you automatic clock goes backwards after exposure to magnetic fields, a demagnetisation service can restore accuracy.
