Glue down dial


vext01

Recommended Posts

Hello everyone,

Having sourced a new pallet fork for my S726A project, I've now reconstructed the movement and it's happily ticking away!

I went to put the dial back on and remembered that it has no feet. The dial was glued down. It's an old Seiko 5 from (at a guess) the 80s. I don't know if that was common practice at the time?

This raises the question of how to reattach the dial. I could glue it down using a tiny bit of glue from my glue gun, but I wonder if there is a less permanent method? What would you recommend?

I know you can solder on feet, but I doubt I have the skill to get that right.

Thanks!

If the watch has calendar works on it sticking dials on can cause problems.

It does indeed have calendar machinery. Day and date.

I have and do solder feet back on having made the machine to do it 

The machine?

As it happens, I do have soldering experience (electronics is another of my hobbies), but I'm worried that it'd be too fiddly.

 

If you were to do it by hand, I guess you'd mark the positions, then solder using one hand to hold the pin with tweezers, whilst using the iron in the other? Would you use flux?

dial dots

This looks easier. If I were to use those, I'd have to apply them to the movement holder. Should work ok?

Thanks

Hi  yes you would use flux. You dip the wire. in the flux and position on the dial, or use solder paste which already contains the flux.  A third hand tool holds the wire and using a small blow torch heat the wire away from the dial. The heat travels down the wire and melts the solder.  A bit fiddly setting up but it works. I personaly use a cold soldering machine using an arc to melt the solder.  Home build not hard to do.

    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
