Hi I have a movement which I think has some serious problem.
I serviced it a week ago but the timegraph shows great gap between results with dial up position and dial down position.
Also the balance seems a little shaky from horizontal view when watch is running.
What can be done to make this watch run in appropriate way?
Hello. I am a hobbyist watch fan. I have recently serviced my Molnija pocket watch with caliber 3602(hand-wound movement).
Watch was back in wonderful state (shown in photos) and ran roughly 40 hours during first day of test.
After couple of days, I noticed that the watch stops after running about 30 hours although it was wound fully.
I opened it up to check what went wrong and surprised to see that mainspring had substantial amount of power remaining.
I guess the mainspring had about 10 hours of power left. What do you think had stopped the watch? Please help.
Hi jdm, thank you for your interest. I have worn this wonderful watch every day for nearly twenty years and there is a fair amount of play in the bearing, not rubbing against workings or caseback yet, but noisier than it used to be.
Thats incredibly bad news. I was sure that this would not happen with the genuine article. I didn't order from Cousins and it will probably be a hassle for me to complain.
And the official answer from Bergeon is the worst. When you are a customer who has paid good money for a product that is defective, you do not want to hear "Well, we acknowledge that there is an issue with your product that renders your purchase useless, but other people have not complained, so you should be fine"
Hey guys! Great information here. Teaching myself some basic watch maintenance. Really just starting out. Bought this with a view to "learn by doing". It wasn't winding when I started. Had an amazing time taking it apart and examining the parts. The hairspring seemed bent so I had a go at shaping it and damaged it even worse. The study came off and was lost, then part of the spring knotted ... Argh. I'm murdering this watch I know!
I'm having a really tough time finding a compatible replacement. The parts chart says that the balance is "different from basic calibre 100" and to "refer to catalogue GF 239". I can't find any document by that name.
If I could get some help it would be appreciated!
