Ok guys I am wondering if anyone here has any suggestions on how to smooth out the crown and stem on a watch I have. I uses Kens' method of getting the threads started but it screws down really rough and I am never really sure first if I am cross threading it and second if it is seated correctly. Ant ideas?

What's the watch?? Maybe the usual silicon based lubricant used on crown and case back gaskets would do the trick: Applied with tooth-pick or thin pencil on the thread.

Sorry I should have said it's my Vortex Pro and yes Oscar it's been that way from the start. The fact that the Vortex has no date there is the extra stem position that would be used to set the date and that might contribute to the problem. Not sure just pointing that out...

I found below tips somewhere on google :D "push down on the pusher while the other hand pulls on the crown stem. Normally it takes only about 0.5 to 1 mm way down and then the crown stem is released. What or who is holding the watch? A movement holder is a good idea for this kind of work. I have however seen watch makers holding the movement in their open left palm, pressing the pusher down with their left thumb while pulling the crown stem with the right thumb and index. This "flying" version can be risky, if you do not have a lot of practise, go for the movement holder or place the watch on the workpad in a way that it will not move if you push down on the pusher. "

This is a : How to remove a winding stem from the movement by pressing the " lock button" located on the movement close to the stem entry ,as one meet usualy on eta movements_ Nothing to do with the screwing of the crown on the case's thread met on diving watches.

Try unscrewing the crown and pulling some waxed dental floss across the threads. This cleans dirt off the threads and leaves a little wax for lubrication. I've done this on rough screwing crowns and they always screw back in like butter afterwards. And yes, I realize I just said "rough screwing."

This sounds like a good idea...Will try this trick on my autozilla: Constated that the thread blackened there due to metal particles accumulating in the thread's gaps. Clouser: Try Molykote 1000 for the rough screwing
