Watch Magnetism Check in the United States
3 listed shops
A Magnetism Check tests whether a mechanical watch has been magnetised and, if so, demagnetises it. Phones, laptops, speakers and magnetic bag clasps can all magnetise a watch, and the usual symptom is that it suddenly runs fast.
The check itself takes minutes, and many shops do it while you wait. Afterwards the rate can be measured to confirm the watch is back to normal.
If the watch still runs off after demagnetising, it may need regulating or a service. A Magnetism Check is a sensible first step before any other work on a watch that has started gaining time.

Frequently asked questions
How long does a Magnetism Check take?
Checking and demagnetising a watch takes minutes, so many shops do it while you wait.
What causes a watch to need a Magnetism Check?
Exposure to phones, laptops, speakers, tablets or magnetic clasps can magnetise the hairspring, which usually makes the watch run noticeably fast.
What if my watch still runs fast after a Magnetism Check?
If demagnetising does not restore the rate, the watch may need regulating or a service, which the watchmaker can advise on after measuring it.
Is a Magnetism Check worth doing before a service?
Yes. It is a quick, low-cost step that can solve a sudden gain in time without any further work on the movement.
