Avia quartz, battery terminal.

Recommended Posts

Hello, everyone!

I have an old 'Avia'  quartz watch and the lower battery terminal has come off.

It seems that it was origionally spot welded into place.

Any suggestions as to how it can be successfully re attached?

Soldering does not seem like a good idea, though the concept does suggest a good way to go. 

Conductive adhesive? Mmmm! Not so sure about that, especially with the constant downward pressure applied by the battery.

Then again, this is the 21st century..............so!

Anyway, all suggestions are very welcome and I feel sure that the answer is out there somewhere.

Thanks.

certainly possible to solder it.

See my repair on an ETA 955 here:

 

You have the advantage of having the missing part, I didn't. And it looks like it is a more accessible place to join. It really now depends on 1: have you got a really small soldering tip and 2: is the movement rare or expensive. Just in case it goes wrong? I was not too bothered as the 955 seems to be readily available.

But to also add, that I have since tried another similar repair on a different movement, again without the part and with even more difficult access and that repair did not work.

Agree with the solder option. I would use a low temperature flux cored solder. Clean both surfaces with a fine abrasive and tin them. Then bring the two surfaces together and heat to make the joint.

 

I'm wearing an Avia just now. A nice neat watch with no pretensions.

That is a ETA 944.111 movement? Not sure but i don't think they are that common this days? If you don't succeed i think i have a couple of NOS circuit boards that was left over from a project that didn't went that well. Movement was to rusty.

    • These are all American movements (with the exception of the "Rubis"), and are all almost certainly "negative set" which means the stem is part of the case. So it's normal that they are all missing- they are with their cases. You will need male square bench keys to wind/disarm them. Vintagewatchstraps has a great writeup on the different systems. But basically, any American "x" size movement will fit any case for that size, possibly with some adjusting of the stem position. With Swiss movements, there is some interchangeability between calibers, usually within the same maker's range, but not really overall- there are thousands of different stems out there.
    • Hi, I'm very new to watchmaking and this is my first time posting here.  I've bought a lot of 10 vintage pocket watches size 0s from e-bay and just got them today.  Most of the balance wheels sprung quite freely and thus seemed like a worthy endeavor as a first batch for exploration.  I've just realized that none of them have any winding stems. Is there any way I could source appropriate winding stems for the movements? There seems to be assortments of various stems selling in bulk on aliexpress, but would any of them fit?  I've read on other threads that some people lathe their own stems (which is waaaay out of my current skill set, which is pretty much nil). Others say that you 'just have to try a few and see if they fit'. I would much appreciate any advice for this matter. Thanks!
    • Nice work.  In the last year, I have been servicing Accutron 218s.  I have the official Accutron hoder that provides electrical contact to the movement.  It is a pretty clever design.  There is a cut in the ring of the holder (shaped like a "C").  When in relaxed state, the holder is slightly smaller than the watch movement.  You spread the cut slightly and drop the movement in and release.  Very clean.  I have made 3D versions of this setup.  Have not explored using it generally for other movements.
    • Double Oooooo   Removal tool? Dreamed of one of these. However, Kalle on Chronoglide showed everyone my system with the pegwood. Worked a treat. Felt so chuffed to be mentioned. https://www.youtube.com/watch?v=tTFrXjiyGKc 46:40 for the wheel removal. Mentions me at 50:00 and does the removal with the pegwood. Felt like my 15 minutes of fame.  
    • Sirius. Thank you for helping others with that information. This is why this forum is so good.
