I am currently messing about with a Chaika 1601 movement which had a very loose cannon pinion (gears turned but hands not moving). I tried nipping it up but managed to mess it up, so it is of no use now. I have got a new unused cannon pinion but it just slips on and has obviously not been crimped (is this normal?).
To fit/crimp it to the centrewheel pinion, do I crimp it in situ (I have a tool that will do this) or do I do it away from the pinion (I do not have a core pin that is small or hard enough to fit, so cannot do it off the movement). The movement is from a ladies watch and the cannon pinion is very small with the bore about 0.3mm.
I seem to be having a run of loose cannon pinions, especially on small calibre (ladies) movements. Don't have a tool for tightening so would like advice for suitable tool. I have seen the Bergeon pliers type but wow are they expensive! Do not want one that needs jeweling tools etc to use it. Any suggestions/sources most appreciated.
Got a ladies Omega De Ville in an auction lot today. My limit for repairs to this point has been installing batteries. The watch runs but runs several hours fast.
I know there are a few reasons it could be running fast. I don't have a degausser but suspect it could be magnetized.
What are some other things I should consider or questions I should ask if I take it in for repair?
Also, do you know if there was originally a plastic retaining ring to secure the movement in the case? There was none when I opened the back.
Not sure if this is the right place for my question since I do not intend to do the repair myself. However I am wondering if anyone knows an approximate price of a tachymeter for the Omega 3520.50 day-date (tripple date).
If anyone has any idea what a insert and the "repair" would cost at a watch shop, please let me know.
Thanks in advance.
So, looking at the diagram I was given, what parts would I need to order?
I just don’t get how the shaft that spins the hands came out but won’t stay in now? And when pulled out slightly it will spin the dates but not the hands themselves.
