Dear friends. I need advise about Omega 1260 movement, recently serviced by me. For some unexplained reason it's just refusing to work... Here what I checked:
1. Both of coils Ok. External and internal resistance Ok.
2. New resonator was installed.
3. New battery was installed.
It's look like the coils don't get the power, but I checked it with battery in and my multimeter says everything Ok - 1.5V
Any ideas please? Thanks in advance,
Emil.

 

I have same watch any help will be graetfull

 

Most likely a faulty transistor. This is common for the ESA tuning fork movements. I have a lot of good coils with bad transistors.
