Cortebert cal 689 - alternatives

[Khan]

Hi

Is it basis of another movement? (Like Certinas based on ETA)

I need a bridge for the setting mechanism and the movement seems very rare. Cousinsuk doesnt have that part either. 

Kind regards

A search on ranfft for the stem or the balance staff used in the cortebert cal 689 only brings up the cortebert cal 688 and 689, suggesting that these are in house movements, however I am no expert. Does anyone else has any experience of these movements?
 

What has happened to the existing bridge?

Thanks for reply, AndyHull

The arm with the the hooked end, was broken - the part, that connects with the setting lever.

I could feel that prior to dismantling, when crown pulling in/out quite weak without tension.

Do you have pictures of the broken parts?

[Khan]

Yes, sure.

If you can't find a replacement, or a donor movement,  I guess it might be possible to silver solder the broken one back together.

You might have some luck here -> https://www.oldswisswatches.com/watch-parts-branded/cortebert-calibre-movement-and-spares/cortebert-688-cortebert-689/

Thank You, will try them. Could be fun soldering if possible.
