Seiko 5 stopped
Discussion
My kid has a seiko 5 with a 4R36a auto movement.
For reasons unknown, it's stopped. Winds ok but doesn't tick! The balance weight also doesn't seem to spin with fluidity either...as though it's stiff? (it has a display back)
Can you replace the movement (cost effective) or could it be an easy job for a watch guy? Didn't know if it was cost effective to start diving into a mass made movement like that???

This was my first experience of modifying - bought a watch with a ruined movement and replaced it with an NH35 (and a new dial and hands) It's fiddly, but unbelievably satisfying.
Note: 4R35 and NH35 are the same movement - it's called 4R35 in Seiko branded watches, NH35 in non-Seiko branded ones.
I've now started making my own watches (slowly, as bits are expensive and I'm poor) and love it.
A new NH35 will cost about £25, and you'll need a few tools in order to make sure you do a decent job. Suggest you get a cheap watch tools set, sold for about £10-15 on eBay and Amazon that will do the job for now. You can upgrade in due course. This initial set will have case opener, loupe, tweezers, hand remover. Try to get one with a blower if you can to remove dust etc.
You'll also need to get some hand pressers. I bought these and they've been perfect https://www.ebay.co.uk/itm/Watch-Hand-Pressing-Too...
The hands are very thin and it;'s very easy to ruin them. Don't use your fingers.
Finally - wear gloves. the watch will look s
t if it's all covered with finger prints. Thin latex gloves from tesco are good.
The NH35 is a plentiful and robust movement. I find it very easy to work with. Here's my first go of doing this:
edit: don't try an take the movement apart. It's next level stuff and the screws and pivots are so small you can hardly see them. You WILL fk it up. Buy a new one instead.

Does the balance wheel look stuck? If it's been subject to a big impact, it might have got messed up (I understand this can happen particularly with S5s). Simply giving it a firm slap (watch flat in the palm of your hand) can correct this problem. If you're considering taking the thing apart, you might as well give this a go!

OP - if you do go down the replace route, I should add that the 4R36 movement you mention is equivalent to the NH36.
The 4R35 / NH35 is date only; the 4R36 / NH36 is day-date.

nice looking watch - Well done. I can imagine the sense of satisfaction doing that.Note: 4R35 and NH35 are the same movement - it's called 4R35 in Seiko branded watches, NH35 in non-Seiko branded ones.
