ryaku 3 Posted November 9, 2014 Unless, of course, ryaku messed with the balance assembly and is not willing to assume it!! LOL Yes, it is possible indeed ryaku, in case you did touch the balance assembly (willingly or not), make sure you re-installed it in the correct position, so that the impulse jewel correctly fits the pallet fork's fork. Refer to the enclosed picture. I didn't touch it. I am fully aware it is a very delicate part and not so easy to reassemble. A hair or something may of got in there whilst you had the watch open? Absolutely yes, it is possible. :( Share this post Link to post Share on other sites

ryaku 3 Posted November 9, 2014 Fix the hairspring before looking for hairs. Not really sure I know what to do here. 10:10, should I remove the balance assembly and put it back again (in the proper way of course)? Thanks again Share this post Link to post Share on other sites
GenTLe 1,510 Posted November 9, 2014 As explained the stop lever fix was successfull but after one night the movement stopped running and now I can see the balance wheel is stuck and doesn't oscillate anymore. I can move it in one direction but it is completely blocked in the opposite way. Keyless work is fine, I can set the time, wind the movement and change the date. As said it doesn't oscillate anymore, at all. No idea what might be wrong. Any suggestion? Thank you ! Yikes! What have you done to that poor hairspring?

Remove it (trying, after you delicately lifted a bit the balance cock with a screwdriver near the screw location, to grab delicately both the balance cock and the balance itself -but not the spring-), put it down upside-down (hairspring in the upper part) and check what's going on there.

10:10 Watch Repair 1 Posted November 10, 2014 Yikes! What have you done to that poor hairspring? It's probably caught on the regulator which was moved. A regulator is not supposed to touch the hairspring when the roller jewel is centered. There should be enough space so the hairspring with be free when centered and touch the right and left side of the regulator when in motion. Rarely are the clone movements (or Swiss out of the box for that matter) adjusted correctly so that happens. Share this post Link to post Share on other sites
