kbiz Posted August 22, 2010 Report Share Posted August 22, 2010 I don't do many manual watch builds and I don't have my cases handy so I thought I'd ask... anyone know if it's possible to put an A7750 movement into a manual rep case?

Drulee Posted August 22, 2010 Report Share Posted August 22, 2010 I don't think the crown tube would line up, but if it did then I think all you would need to do is cutout the tab slots in the right location, depending upon which movement ring used (DSN is a different size than the Cartel ones), and probably use a DSN caseback (as the thicker Cartel ones would probably push against the rotor).

kbiz Posted August 22, 2010 Author Report Share Posted August 22, 2010 I think it'd be easier to make a custom movement holder... Quote Link to comment Share on other sites More sharing options...
Drulee Posted August 22, 2010 Report Share Posted August 22, 2010 I think it'd be easier to make a custom movement holder... Easier than what? I'd think taking an existing DSN or Cartel one, then just cutting out the slots in the inner case would be easier than milling a brand new retainer ring? Or are you thinking of just using a plastic one that uses the case back to hold it in place? Quote Link to comment Share on other sites More sharing options...
kbiz Posted August 22, 2010 Author Report Share Posted August 22, 2010 no way, milling slots in the case is much more difficult... harder to measure, harder to set up and riskier... movement rings aren't very hard to make. most likely an available movement ring wouldn't even fit on one of the dimensions... oh and I would never allow plastic in a watch Quote Link to comment Share on other sites More sharing options...
sssurfer Posted August 22, 2010 Report Share Posted August 22, 2010 I think it is not possible, as the manual case is made for the 6497 movement which is one of the thinnest movements around (4.5mm), while the 7750 is one of the thickest (7.9mm). Besides of that, you would also encounter stem alignement problems as already foreseen by Drulee. Finally, and especially about your crystal idea, the rehaut of manual case is much shorter than that of auto case. So you might also encounter problems to have the cyclops fit without touching the minute hand. Quote Link to comment Share on other sites More sharing options...
kbiz Posted August 22, 2010 Author Report Share Posted August 22, 2010 especially on GMT movents I bet... Quote Link to comment Share on other sites More sharing options...
sssurfer Posted August 22, 2010 Report Share Posted August 22, 2010 I'm afraid so. The added height from the GMT hand lets me suspect that the minute hand might be placed even higher than on non-GMT models, so that touching the cyclops might be even more likely. Sorry.

sssurfer Posted August 22, 2010 Report Share Posted August 22, 2010 BTW, I placed a 2892 into a manual case, and it was a nightmare to get the central second hand running without touching the cyclops. Quote Link to comment Share on other sites More sharing options...
kbiz Posted August 23, 2010 Author Report Share Posted August 23, 2010 well Gen has recessed cyclops so doesn't stick out at all... so if it works a manual case with manual crystal it would work with the auto crystal but the hand stack is still higher than manual wind...

rolli Posted August 23, 2010 Report Share Posted August 23, 2010 what a strange question !!!!!!!!!!!! why is it necessary to know it ??????????? auto movement in a auto case, handwind movement in a handwind case. and nothing else. rolli Quote Link to comment Share on other sites More sharing options...
kbiz Posted August 23, 2010 Author Report Share Posted August 23, 2010 reason I'm thinking about this is it might then be possible to install a gen auto crystal into a rep case Quote Link to comment Share on other sites More sharing options...

rolli Posted August 23, 2010 Report Share Posted August 23, 2010 but it is very clear that this is not possible to make a handwind case to a auto case. the measure from dial to the case-tube-center is different. same with the sapphire, both have different measurements. rolli If everyone thought like this, there would not be much innovation in this world Come on Rolli, you're a long time member, you should know that in the rep world you have to work with what you've got Quote Link to comment Share on other sites More sharing options...
