ceejay Posted April 21, 2014 Report Share Posted April 21, 2014 I'm a bit of a masochist, that's the only reason why I bother servicing the 2813 movement (only my own) and for practice, because after one of these everything is simple in comparison. I haven't done chronographs yet This is the reason why most sane watchmakers will say "just put a new movement in" What we are looking at is 7 pinions waiting to be located into the holes of a single bridge, 1 doesn't actually locate it is retained by a sprung plate and the other on the barrel is fine. That leaves 5 wobbly pinions that will jump out of the jewel holes (top or bottom) just by looking at them! 45 minutes is my record and I considered that 'luck' If you see this movement...run! 2 Quote Link to comment Share on other sites More sharing options...
Rolexman Posted April 21, 2014 Report Share Posted April 21, 2014 Nice practice. Time to step up to the chrono's if you have the patience and steadyness for this stuff Quote Link to comment Share on other sites More sharing options...
Jkay Posted April 21, 2014 Report Share Posted April 21, 2014 I have done this (for myself) and I absolutely agree. One plate and a handful of gears to align simultaneously !!! Quote Link to comment Share on other sites More sharing options...
ceejay Posted April 21, 2014 Author Report Share Posted April 21, 2014 Yep RA, I am carefully studying the 7750, I have 2 sitting here requiring a service. An ETA & an Asian. The Asian will be getting some attention soon The dial side of the 2813 caused me quite a few headaches too with the click (?) springs that would launch themselves across the room every time I smiled! The fun of spending 15 minutes on my hands and knees with a magnet...good times I will look back on with fondness (sic) I have the 2813 whipped now though apart from the 'bridge of doom' Quote Link to comment Share on other sites More sharing options...

The Asian will be getting some attention soon Start with the ETA. Less frustrating and easier to work on. Also spare parts are readily available. The A7750s are in a league of their own.... they need to get used to 1 Quote Link to comment Share on other sites More sharing options...
krpster Posted April 23, 2014 Report Share Posted April 23, 2014 Yup, that bridge is a PITA. Definitely designed around inexpensive manufacture and not servicability. Quote Link to comment Share on other sites More sharing options...
