Seiko 5 running fast
Discussion
My watch was fine for years but then started running fast. About a minute per hour.
I have spent this week moving the adjuster in the back by small increments towards the minus sign.
Now at the max position but no difference in speed, still a min/hour approx.
Any ideas?
I thought maybe a service but as I only paid £50 for it, thanks to a thread on here a few years ago, it may not be economically worthwhile.
Cheers.

Cheers. I've tried the tapping, no good I'm afraid.
Just checked with a stopwatch on the phone. The Seiko is 3 secs fast a minute even with the adjuster at its lowest setting.
To be honest it doesn't seem to make a difference wether it's on neutral or fully minus. Maybe the adjuster is at fault.
There are two tiny levers both with brass looking ends. One moves the pointer between + and -.
Should I be doing anything with the other one?

Yours sounds magnetised - get a demagnetiser off ebay for about £6 and that should fix it.
Sounds like a hooked-up hairspring to me, very common on basic Seiko movements.
The outer complete turn or the hairspring can "jump" to the wrong side of the regulator pins if the watch gets jolted with the balance in the right (wrong) position. Easy fix once the back is removed - a very gentle prod with a cocktail stick in the right place.
