Just in today, watch has been recently serviced and many other service marks recorded over the years 2000+. Seems like someone had problem with timing. innovative use of glue!!!!... picture not the best but you get the idea.
Had a closer look, the glue has chunks of metal pressed in. Just out of curiosity I put the balance in, not surprisingly its way off, no doubt another ebay sale “recently serviced”
Chris that is ugly!!! Would have been a lot easier for the "supergluer" to just replace the missing balance screw to bring the watch back to timing. Good luck cleaning that up!! Yikes
