Have I damaged my watch?
Discussion
Hi,
Did a stupid thing yesterday, I took my H3 Traser off and gave it to the Doris while I helped move some stuff round a mates. She put it in her bag to keep it safe, but also in her bag was her NHS namebadge which is attached to clothing by...2 very strong neodymium magnets. Typically when I retrieved the watch a good few hours later, it had found it's way next to the name badge and had stopped.
I reset the time and it seems to be working ok now, but I haven't checked the accuracy of it as yet. I mistakenly thought watches were anti magnetic, but not so. I haven't b
ksed it have I?, be gutted if I have as it was a Christmas pressie.

Time to worry when you have bothered to track its accuracy over the next few days.Did a stupid thing yesterday, I took my H3 Traser off and gave it to the Doris while I helped move some stuff round a mates.

Automatic or quartz?
If it's quartz you won't have done any harm - strong magnets can affect them by preventing the stepper motor from "stepping", which makes them lose time or stop until the magnet's removed but has no lasting effect.
If it's automatic then you may have magnetised some parts of it - mainly the keyless setting work - which can affect accuracy slightly thanks to dynamic effects, but probably not at a level you'll notice in daily use. Basically, a fast moving metal balance in a magnetic field will tend to act like a magnetic brake. The days of magnets having huge effects by sticking hairspring coils together are pretty well gone thanks to alloy balances and hairsprings.
Even if you do see an effect, demagnetising is straightforward and should be pretty painless to your wallet

Demagnetising your wallet is far from painless. You'll wipe the mag stripes on the credit cards.
