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.

    • Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.
    • This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.
    • After a bit further research could it possibly be an AS 970?
    • Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner. 
    • Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
