Watch repair
Time for another watch repair!
The watch can be winded up to max, but it does not move nor tick, so my guess is that the gear train is stuck somewhere.
It is also the first time I use my microscope to something else other than soldering components (and looking at creepy bugs with my kids..).
Take it apart
I started to take everything apart as usual, starting with the balance wheel. Next in line is the gear train starting with the last gear and work myself forward.
When I inspected the third wheel in the gear train, it was a little tilted and did not align properly. As soon as I lifted the gear up, the whole mainspring unwind at once. It really scared me :-(
Here is the bad guy:
The jewels did not look that good either.. they were full with dirt and dried oil and really needs a bath.
I haven't found my small baskets to use in a ultrasonic washer yet, so it has to wait.
The result
I did not see a point in continue to take it more apart without be able to clean it properly. So I did put everything back so that I will not lose any parts. The watch started to tick though, so the problem was probably the misaligned gear.
