Alternative for this old comon japanese movement?

Recommended Posts

I've been doing some work on this watch for a customer, and it keeps playing up (due to repeated water ingress) I believe i got it working okay again, but I think the movement should really be replaced, as a pretty standard size hour/minute quartz movement I'm sure I could find an alternative of some kind, but I'd rather not have to cut off dial feet or re do the stem/crown if I can help it. Does anyone know any kind of calibre number for this (none is present on the movement itself) and what the closest alternative is? Thanks.

I'm assuming you guys mean a 2025.  There's no second hand. Also as I said I'm happy to find an alternative if I have to, but I'm trying to keep the standard up as the customers already had problems. I was wondering if anyone knew of a near perfect alternative, one that would fit the original dial feet and maybe even the stem. (the first part being the far more important)

If there was a calibre number I could have likely answered that question myself with what's already on the internet.

Mmm...
Repeated water ingress is going to wreck any movement. I think you need to upgrade your customer!
Seriously, the movement shape is common to a wide range of Seiko movements ancient and modern. You'll need to match the dial side to find a suitable swap or use dial dots. As for the stem, I've found that even an exact movement swap need a new stem cutting due to wear patterns and different tolerances.
I can't read the inscription on the movement (is that due to my iPhone or my eyes?) but I presume you can't get a clue from that.
I have a selection of dead movements to trial fit in this sort of situation.
Good luck Neil

You need to measure the existing movement for a replacement. The height of the movement, hands height and size of its overall dimensions is required. I have changed many of these style of movements and in my experience sticking to the original make i.e. Miyota, Epson etc is best because the hand pipes fit. The cost is also negligible with some movements costing as little as £3.00 so it's hardly a big risk when ordering. The replacement fitting is a very easy job.

I just got back to work so time to have another look. The picture isnt very clear but it reads 'Miyota one 1 jewel unadjusted japan' i should have mentioned the manufacturer before. 

Ive seen so many of them in old watches I thought someone might know straight away. Hopefully ill find out this time and just remember for next time. Its a little smalle than a 2025, time to do my research and measurements.

    • Hello and welcome from Leeds,England.  Ask away. 
    • What cutter are you using can you video the action 
    • Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement. 
    • if you're trying to keep track of conversations scattered all over the message board emails are an absolute must.   looking at the bell icon on the top of the page versus the emails today it looks like I got the correct amount of emails. So making some minor change based on the one of the images up above I started getting notifications again. But at times I still have a suspicion that something isn't quite right. I have some feeling that the message board may delay sending emails until something so seems to be a long delay between when you get your emails just a weird feeling things aren't quite right oh  and then even though I do seem to be getting emails I no longer get notifications of personal messages I don't find that out until I arrived at the message board where I'm pretty sure I used to get notifications of those two. So something is definitely changed on the message board. then for everyone not getting emails you do want to check your spam folder. I have found that sometimes were open up an email the system I use warns me that it thinks the email is evil and bad and I have no idea why he thinks some of the emails are and some are not. But this is actually the program I use not the email system which also has a mind of its own as to what it considers spam so you should always check your spam folder.
