HauteHippie Posted July 5, 2011 Report Share Posted July 5, 2011 Hey folks. Does anyone know, offshore maybe (?), what is the standard bevel angle used on watch crystals? It does not look like a 45° angle on most of mine. I'm thinking maybe 30° or so? Anyone know? Thanks, Chief Link to comment Share on other sites More sharing options...
txcollector Posted July 5, 2011 Report Share Posted July 5, 2011 I can check but I believe the engineering constraints will dictate 40°. I have to search my notes though. Link to comment Share on other sites More sharing options...
HauteHippie Posted July 5, 2011 Author Report Share Posted July 5, 2011 Thanks, bud. Let me know when you get a chance to look it up. I guess it probably varies from one make to another, too. So there may be no right answer, other than a maximum. Link to comment Share on other sites More sharing options...
RWG Technical Posted July 6, 2011 Report Share Posted July 6, 2011 It varies between the crystals, there is no standard that I have noticed. Typically you need a slight chamfer on the edge to be able to insert the crystal into the seat, but otherwise it's all over the place... Most critical is the diameter, anything beyond + - 0.05mm of the required dimensions and you could have problems, too loose or too tight in the compression ring.
