cjjoyce1 Posted March 18, 2011 Report Posted March 18, 2011 Can any experts out there tell me if the gen 5512/5513/1680's had some sort of gasket between the crystal and case? I've noticed looking at the case profile with the crystal off that there is a lip around the top of the rehaut or rather a groove cut in the case. It would appear to be a space where a gasket of some sort would live. So in cutaway view you would have retaining ring, crystal, gasket, case. It would seem to make sense as without some sort of glue or sealant I can't imagine a pressure fit ring and crystal would be watertight to 200m-600ft, but then again I am often wrong!
rosnik Posted March 18, 2011 Report Posted March 18, 2011 I'm not expert..wile. No Crystal gasket on vintage Gen SUB. there is only one 'retaining ring' gasket .
cjjoyce1 Posted March 18, 2011 Author Report Posted March 18, 2011 That's sorta what I thought, but that little groove really got me thinking. I even have a nylon gasket from god-knows-what that fits in the groove, too. With a bit of work the rep crystal snugs over it.
lloyd Posted July 9, 2011 Report Posted July 9, 2011 I believe the lip cuts into the crystal when the retaining ring is pressed on and creates a seal. Putting an o-ring there would prevent that.
