krpster Posted March 23, 2011 Report Share Posted March 23, 2011 I am trying to determine if ETA/Valjoux movements use the same size screw for attaching the case clamps. Main reason I a asking is that I have a donor watch with a Valjoux 7734 but it does not use case clamps (or perhaps they were removed :dunno: ). So I need to get some new ones but I am not sure if I need ones specific to the movement or if others will work (ex: ETA 28xx). I don't have any handy at the moment to try so I thought I would throw it out there to see if anybody knows. Thanks! Quote Link to comment Share on other sites More sharing options...
krpster Posted July 29, 2011 Author Report Share Posted July 29, 2011 Bumping this one up again to see if anyone knows. I tried some that I had from 21J as well as 28xx series and they are too small. Does anyone have the specs for these screws? I tried searching the web but it only ended up bringing me back to this post Quote Link to comment Share on other sites More sharing options...
Rolexman Posted August 5, 2011 Report Share Posted August 5, 2011 As far as I know all movements have slots for case clamps. Post a picture. There are variations between screws. Not all ETA screws are alike. Quote Link to comment Share on other sites More sharing options...
