MADRED7 Posted September 18, 2007 Report Share Posted September 18, 2007 Dear all, I am about to change the crown and tube on a PAM249. The watch has got the UNITAS 6497 and a screw down crown....because I don Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted September 18, 2007 Report Share Posted September 18, 2007 The ETA 6497 stem is 1.20mm. You can't use stem extension to make it fit on a 0.90 crown, there is not enough distance between the movement and the case. RG Quote Link to comment Share on other sites More sharing options...
MADRED7 Posted September 18, 2007 Author Report Share Posted September 18, 2007 Thx The Zigmeister for the fast reply..... I talked to CousinsUK and the do have all the things I will need (crown, Stem-extension) but I will take your advice...using the extension will make the stem too long. Thx for saving me some GBP Theo Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted September 18, 2007 Report Share Posted September 18, 2007 My pleasure. The problem with the 6497 is that there is no movement spacer, due to the size of the actual movement. No spacer means that the movement is right up against the inside of the case, which means no space for an adapter. Believe me, I tried when the Gen PAM crowns were for sale, and members wanted them on the handwinds...can't do it... Any money I save you, just send my way for my kids college fund RG Quote Link to comment Share on other sites More sharing options...
