Trident C60 suddenly gaining time - reasons?

Post by tom_uk »

In the last 24 hours I’ve suddenly found that my C60 Trident has started gaining significant amounts of time, i.e. it’s running much faster than normal.

Yesterday afternoon I spotted that it was about 5 minutes fast so I reset it. My working assumption was that perhaps I’d reset it wrongly earlier in the week - it needs resetting at weekly intervals having gained a minute or so in that time and I wondered if perhaps I’d reset it to the wrong time when I last did so. However, this morning - 12 hours or so since the last reset - it’s gained another 2 minutes.

I’ve searched the forum and I’ve discovered the issue of the watches becoming magnetised and I suppose that’s possible. However, I’m not normally around magnets - we don’t have a magnet as such in the house - so I’m not sure if that’s how it might have happened. I don’t have a compass to check, either. (Actually, it has just occurred to me that earlier in the week I was handling my wife’s new Apple HomePod, which I imagine has magnets. Could that type of equipment have affected the watch?)

The watch is a seven and a half years old C60, and it was serviced on schedule two and a half years ago. It’s worn every day - certainly every day in the last few months - and left on a bedside table overnight (maybe 8 hours). I can’t recall dropping it or subjecting it to a shock recently - or ever, in fact.

Can anyone think of anything that might have caused this?

Most likely cause, as you have already identified, is that it is magnetised.

Phone, tablet, loudspeaker etc. are the most likely cause.

If you do not have a compass to test, I believe there are a number of Compass Apps available to use on a Smartphone that will work in the same way.

Good luck.

I would check first with a pocket compass. Hold it level, let it settle, bring the watch up underneath it and if the needle starts to swing significantly out of line it’s a sure sign the watch is magnetised. Any watchmaker will have a demagnetiser and should be able to fix it for coppers.
The half minute which we daily devote to the winding-up of our watches is an exertion of labour almost insensible; yet, by the aid of a few wheels, its effect is spread over the whole twenty-four hours.
