[Closed] What's wrong with my Seiko 5?

My 10 year old Seiko 5 watch has started to gain about 15 seconds per minute!

It has kept relatively good time previously - it used to gain about 5 minutes a week.

I can't remember dropping it, or exposing it to any magnetic fields.

Will a clean and regulation fix it or is it toast?

I have a Seiko automatic from the 50s that I inherited from my Grandad, so I was hoping to get a similar lifespan out of this watch. 🙂

Might well be worth getting it serviced, although finding someone who can/will service a mechanical watch might be a bit tricky, and almost certainly won't be cheap.
I know of someone who has in-house watchmakers who could do it, but their branches are in Marlborough, Swindon and Royal Wootton Bassett, if that's any help.

These guys sorted my sk007 after I dropped it. Very reasonable cost. http://www.rytetimewatchrepairs.co.uk

Emmet Brown?

Seiko Sportsmatic 17 Jewel Diashock automatic.

Might be the 1960s but early 1960s.

CountZero - Swindon is doable as I'm in Oxford.
Oblongbob - Cheers. What was the rough order of cost? A new watch like mine is £62 via eBay, so I'd spend up to that, but no more.

Here you go: http://www.deacons-jewellers.com
They did a good job of fixing my Yema Rallygraf, when the mainspring broke. That's a totally mechanical French-made chronograph from the late 60's, finding anyone who could fix it was difficult but I got lucky with Deacons, as I'm in Chippenham and both Marlborough and Royal Wootton Basset are pretty close, I went to Marlborough as it happens, it's a slightly easier drive and a nice town to wander round for a bit.

Not guaranteed but likely that a service will cost more but it's the eco friendly thing to do ;).

There is apparently a catch internally that the mainspring can get caught on and the accuracy goes very quickly. The actual fix is a full service, but the ghetto fix is a sharp tap to the back of the watch (watch face down in palm of left hand, hit it sharply with your right). There are various forum posts explaining the logic better than I can. This may or may not work, but for my money it's worth a try - if it fails then you'll need to pay for a service anyway.

YMMV of course. FWIW this didn't work for mine but plenty of people report good results.

It's Brexit.

The British minute has devalued against the European minute.

Many workers are euphoric about the resulting shorter working day.

I tried giving mine a whack but alas it didn't work.

OP, I can't remember the cost exactly, but it was about £50. I did think about just getting a new one, but I decided to get it fixed as new one would have been fair bit over 100 and they were looking a bit thin on the ground at time. Also, I have a broken 5 in my drawer already and felt a bit bad about growing my collection of broken watches.

Probably a 7s26 or 7s36 movement, really cheap to buy new so few people bother to service them.

Usual practice was to buy a $50 5 and swap the movements then sell the unwanted watch and old movement for $20 to an amateur horologist.

Have to be more careful now as the base 5's use a 4r36 which need a different crown/stem.

Look on Ebay for NH36 (seiko movement used in other brands).

From someone who worked for Seiko, the Seiko 5 is cheap rubbish. Just replace it.
