In fact, the watch is working well, so hopefully, I don't see the necessity to repair for now...
I was curious about this electrical contact anyway... maybe this is the electrical connection to "0 volt" for the caseback, for magnetic interference protection...?....
You're right, repair seems in all case very difficult... maybe an electronic specialist could weld it...
@Archer : thanks for these infos; do you think watchmakers have still access to a complete caliber?...
