Surely a two pronged approach?
Explain to your watch guy the problem, if he gets the back off he should be able to tell you it's serviceable or that tyhe movement is toast.
What is the collective opinion on servicing a Seiko basic movement?
My Sumo is now running around a minute slow per day. I don't think it has been magnetized and I don't recall bashing it on anything recently. From the caseback it's a 2015 production date.
Is it worth getting the 6R15 serviced or just buy a new movement and get someone to fit it?
I think a new movement is going to cost around £200 v service around £150 or there abouts. I assume fitting the movement would be about £50.

I had an issue with a 6R15 that I think was a couple of years old, it was suffering from very low amplitude (sub 250 if I remember correctly) and was giving very inconsistent timing,
I replaced it myself with a NH35 as it was only about £35 from cousins versus £70 or so for a NH15,
Best get it on a timegrapher as if its showing healthy otherwise and it's consistently loosing 1 min rather than all over the place it may just need regulation.
I'd always prefer to service a movement than buy a new one if it's serviceable, and economically viable.
Do you have an independent you use, or would you send it off to Seiko? If the latter, they may make the decision for you.
If you use an independent let me know who they are, cuz that seems a good price!
You could spend about a tenner on a case holder and caseback remover, five minutes on YouTube and have a crack at regulating it. Hard to do precisely without all the kit, but if you gained that minute back it would be very satisfying, and cheap.

Thanks all, I will have a think on this. I am loathe to just leave it sat in the box as I really do like the Sumo as a knocking about watch.
If its consistently one minute I would just tweak it, 10 minute job.
I don’t recommend this unless you really know what you’re doing. I’ve fixed a couple of these where the hairspring has been wrecked as a result if someone attempting regulation.
Fitting a new movement isn’t usually my preferred option, the replacement movements are often badly oiled, last time I fitted one I ended up stripping it down and re- oiling it. I prefer to work with the existing movement unless it’s in poor condition or damaged.
Well gents, to answer a few questions, the watch isn't worn daily, maybe a couple of days a month. I do make sure it runs every week though.
I haven't banged or dropped it that I recall, but that isn't to say the other family members haven't and not owned up!
I have emailed Seiko UK and they will service it for £135 plus VAT so I will send it of to them as someone suggested earlier.
Sent the Sumo for some TLC at Seiko UK.
Got it back after a paying a hefty bill (£283). Charged me for a new crystal (the old one was scratched) I didn't want it replacing but it was done anyway. Also charged for fitting the bezel, I had removed it to clean it up before sending it in.
Lesson learned with this experience. My Rolex service, in context, was much better value.
Currently running 5 seconds a day slow after 3 days on the wrist.
Anyhow, here it is and I am pleased to have it back again.
I would of sent it to Duncan/thewatchbloke, prices below and he would only do and charge you for what you wanted doing.
The above prices are for a full movement service only, and don’t include replacement parts or return postage. Any additional work costs £35 per hour and after the first hour it’s charged to the nearest half hour.

That's the trouble with cheaper watches unfortunately.
They still take the same time/skillset to work on as as their more expensive brethren so the repair cost/watch value ratio is somewhat skewed.
I had a quote to service a 007 of mine but TBH it would have been more cost effective to just buy a new one.
Cheers,
Neil.
I don't resent it really.
The watch is too good to throw in a drawer and forget about it. If my eyes were better, and hands steadier, I would love to be able to do my own service. Unfortunately those days have passed by!
I took an old watch apart a few years ago and realised very quickly I was out of my depth.
Interesting thread... my SUMO has a noisy rotor all of a sudden. Seems to keep time, but runs out of puff in under a day.
Will have a chat with Duncan and see what's doable.

I sent a Seiko back to Seiko UK to be checked under warranty. Came back with a fingerprint on the rotor and after a month or so (once the warranty had run out) the timekeeping was back to the same problem. Sent it to Duncan who did his usual excellent job and it’s been working fine ever since.
Wouldn’t touch Seiko UK with someone else’s barge pole
