chris5264 Posted November 4, 2014 Report Share Posted November 4, 2014 I've worked on tons of unitas movements. Lately the last few reps all seem to have the same issue. I also take any luminor pam apart when I get it...make sure all the O-rings are greased and then when I put the crown back into the keyless works it always seems very fussy as if the stem isn't long enough. When I try to push it back after setting the time, it will not click back into winding mode unless you slam the crown guard. Is this just from the keyless work not having any oil? is there a trick I"m missing? The stem isn't too short...sure of that.. Link to comment Share on other sites More sharing options...
Rolexman Posted November 5, 2014 Report Share Posted November 5, 2014 The 64xx series has the most stable keyless work of them all. Just don't unscrew the release more than 1,5 turn and make sure the crown is in winding when you remove it. You don't need to slam anything. Just some finesse and a wiggle to slide it through the castle wheel. Link to comment Share on other sites More sharing options...
chris5264 Posted November 5, 2014 Author Report Share Posted November 5, 2014 Thanks rolexman...yes..I've unscrewed it too far enough times...but this is stranger...I'll get a pam rep...works fine..can set the time and then push the crown back into the winding position. Then I'll take it apart and regrease the gaskets but when I put the crown back in and it no longer will change from the time setting to the winding position because the spring in the crown doesn't push hard enough to reset the keyless works. I can only get it to get back to the winding position by using the crown guard. If just happened once I wouldn't think about it but is the case with three pams now.

Rolexman Posted November 5, 2014 Report Share Posted November 5, 2014 Aaaaa thats normal with reps. You are doing it right Link to comment Share on other sites More sharing options...
chris5264 Posted November 5, 2014 Author Report Share Posted November 5, 2014 so just some oil in the right place in the keyless words would probably take care of it? Link to comment Share on other sites More sharing options...
Rolexman Posted November 6, 2014 Report Share Posted November 6, 2014 The problem lies not with the keyless works so oil is not the solution. The crown stem is too short. Link to comment Share on other sites More sharing options...
chris5264 Posted November 6, 2014 Author Report Share Posted November 6, 2014 That was my first thought...but here is why I"m so OCD about this. When I first got these reps it worked fine. could set time and push it in for winding without and issue. It was only after I took the stem out and replaced it that it wouldn't fit in the same way as it did before. I even tried replacing it with a longer stem but didn't work because with the crown guard you can only get the stem so long and just didn't look right sitting next to the case.

Rolexman Posted November 6, 2014 Report Share Posted November 6, 2014 Maybe the entire movement and dial shifted a bit. Check the movement holder tabs. Just some extra tenth of mils to the left or right could make a huge difference. Link to comment Share on other sites More sharing options...
chris5264 Posted November 6, 2014 Author Report Share Posted November 6, 2014 now that is an interesting hypothesis....will test it out...really the only thing that makes sense...if it was oil on the keyless works then it shouldn't have worked right when I got it. Nice...even if its wrong it the best guess I've head since I had this issue. Link to comment Share on other sites More sharing options...
