Hi All
I purchase Bobs course awhile back but dropped playing with watches for awhile . I now have picked it up again and have recently ran into a problem I can not figure out.
I took apart and reassembled an ETA 2892-A2 movement that was 20 years old and working well. I just decided it should go through a service anyway. first mistake lol. I have service a few different type movements including a clone Chinese 2892 with no problems.
I just purchased a timegrapher 1900 and can usually get good results, but I am not yet able to use it to analyze problems.From what I read It points to the escape wheel or the fourth wheel as the main culprits ...But I went over everything and I see nothing wrong . I have taken apart and rebuild this movement 3 times with the same results. I am about to change the whole drive train part by part till I find out whats wrong . Is there an order what I should be looking to replace first second etc. Or can someone decipher these graphs and point me in the right direction.
the next three shots are crown right, face up, face down.
Thank You
Anthony
