Had a little scare!
So I pulled my GMT out to wind it up and when I tried to screw the crown back down it was only going in 75% of the way.
I’m always careful not to cross the threads so I didn’t want to force it any further. I unscrewed it and tried again, same thing happened. You can see from the picture that the crown looked like it was hitting one side. I know the threads are a little dirty so that may have something to do with it? Well, I tried to pull it out and screw it down again and this time it worked like normal. Any explanation for this incident? I’m hoping it was a freak thing that only happened once because of some dirty threads. See the pics and let me know what you think. I held my loupe up to my camera phone. |

Do not worry, it sometimes doesn't unscrew totally.
For the non-centered crown, I do not know: if it touches the crown guard, go to your AD...

This happened to my GMT Pepsi immediately on return from RSC and it went straight back for rebuild. Apparently there is a set screw that holds the stem in place and if loose means the stem will come right out. I would suspect, therefore, that in you case that set screwed is, well, screwed-up.
BTW, where'd you get your GMT Pepsi? |

Sorry that happened. Cool thing you did with the loupe and camera phone though.

Are you sure the threads seated properly when you screwed it in. I always back up the crown until I feel them bed in and then screw it down

Yeah, I do the same thing. I have since unscrewed and screwed it back in a few times without issue. I hope it was just one of those things...

I have had that issue with a GMT I had. It was a new watch and it only happened a couple
of times. I could not see anything stripped or out of place, so I dismissed it. I think it is a thing with Twin-lock crowns, as I never had this phenom with a watch with a Trip-lock crown. |

That insert thread does not look worn or damaged and if the insert thread is ok then the crown thread should be ok.
I would give it a wash out with hand sprayer, blow it dry and apply a little lubricant. A touch of vaseline or silicone grease works for me. No smart remarks thank you.
