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 was also going to suggest some sort of miyota 2035 movement as the shape seems similar but not sure about the dimensions.

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.

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
