I have a nice case and dial so decided to make a custom watch for mrs eezy with a new Miyota module.

No dial feet so I used sticky dial pads. I put it all together, it worked fine and looked good so left it on my bench for a few days with the back off. Eventually decided it was OK, put the back on and presented it to mrs eezy. It ran for about 24 hours before it stopped so I reset the time and ran it for a day or so. She wore it and it stopped again.

So further investigations and I find if I hold the watch vertical and tap it, the hour hand moves. The hands are new and not loose so I start thinking.

Conclusion:- The dial is not flat, it's convex, but the module is flat meaning the edges of the module are touching the dial but the hour wheel has a gap above it allowing it to jump out of mesh, even though I inserted the wavy washer.

Ah well, a novice error I guess :)

Can't you simply shim it with another washer?

Yes but those washers are so thin that 1 won't make much difference.

I've since had a thought that I could put another wavy washer on the other way up and that should work. I could shim it with anything but it's about calculating the size of the gap.

Hi  unfortunatly shimming in this case will be a matter of trial and error to achieve the correct gap. Try putting a bit of rodico under the dial then fitting it then remove dial and measure the thickness of the rodico after being squashed you will be near the size required

Plastic is nice...but it doesn't give you an excuse to have a cold one.

Actually I was trying to work out if I could use the top off a vodka bottle.

    • To start searching for hands, measure the diameter of the hour wheel where the hour hand attaches, and the tip of the cannon pinion where the minute hand attaches. Use calipers that are accurate to 0.01mm, and then you can look around ebay for hands about the right size. It is typical to have to either close down (concave punch) or broach open the pipe when fitting hands since you won't usually find a set that is the exact diameter of your hour wheel & cannon pinion. It is reasonable to work with something about +/- 0.03mm  Measure the thickness of the 4th wheel extended pivot for a seconds hand. Cousins does sell some new hands for pocket watches, but I don't find them suitable for old watches. They just don't look right so instead I managed to win an auction on an enormous assortment of old hands. It's sort of fun to pick through them and measure to find a workable pair. I use this tool to measure hands:

    • I'm looking for hands (3) & a crystal (4cm dia.) for my watch Serial No. 85590 as shown in the photo. I'd be grateful for suggestions re potential sources; and to know if uv glue would be suitable for re-fixing the 12mm dia. seconds dial.

    • Welcome to the forum, enjoy. The issue is watches that are sold as  waterproof are only valid if serviced and fitted with new gaskets fitted particularly those that are around the stems.A picture of the watch would be helpful for a better analysis..
