I've just replaced a balance staff on a Bulova 10AK movement from WWII with a NOS Bulova 7AK staff (according to jules borel, these should be interchangeable.) I also had to replace the roller jewel (I sourced a roller jewel from an AS 1194, again, interchangeable). Now the watch is running wildly differently depending on which side is up. I've attached some photos, keep in mind my timegrapher is just a phone app which uses my phone microphone , so some of the random blips may be outside sounds. Back side up the movement can be regulated pretty close to accurate, but when the dial side is up it runs CRAZY fast. Could anyone explain what went wrong/what may be the issues and potential solutions? Thank you for any help you can give!
Beginning Watch Repair Questions
tjb posted a topic in Watch Repairs Help & AdviceHello All I have started my watch repair learning! I have read a few online guides on how to repair watches. I have also acquired most of the necessary tools for watch repair. I have started out by cleaning two watches. The first watch I attempted to clean was a Bulova 10AK movement watch. This watch did not run before I cleaned it, nor after! Before I even took apart the watch, the balance wheel was wiggly. I could easily rock it from side to side. This is what I think was causing the problem. I cleaned it and put it back together but it still didn't work. Could someone explain why the balance wiggles like it does and how to fix it? This also happened on the second watch I got: a Hamilton 982 movement watch. This watch ran before I took it apart, but after cleaning it, its balance wheel has the same problem! I really do not know what to right now, so any help would be appreciated! A few more questions: - How do professionals make their movements so clean that they sparkle after cleaning them? I used an ultrasonic cleaner for my second watch, but the results were good, but now perfect. - Both watch cases aren't in very good shape. Where could I send watch cases to be restored? - Where should I send a dial to be cleaned? - Should I have professionals repaint the hands or should I do it myself? - What kind of crystals would you recommend for each watch? - What gasket should I get that goes in between the case and crystal on the Bulova? Any help with any of the above questions will be very helpful to my learning experience. Thanks!
