Cross threaded crown?

[Onikage]

This is probably nothing but I felt sick at the time. My watch had been sat for over 48 hours and completely wound down. So I was setting to my atomic clock as usual but when I came to screw the crown back in it must have caught wrong, it didn't screw down very far thankfully, but it caught right at the end of the stem and it just span around either way, it wouldn't pop out or screw back in! It seemed to fix itself after a little playing and popped out then screwed down normally. Should I be worried? I've popped it out a couple of times today and it doesn't seem to have a problem now. Erk!

You may have saved the day if it only happened at the start of the thread. If it is screwing backwards and foreward again as normal you may have caught and sort of recut the thread again so it could be ok. If you are still a bit worried you could take it to a watchmaker just to check its ok.

Yeah it was only at the very start of the thread, it just didn't catch properly or so it felt. The thread's title is kind of an exaggeration. Cheers. That's made me feel better about it. What better place to seek reassurance about watch problems than here?

The best way to avoid cross threading is: To tighten crown - place your thumb - finger print surface - on the crown and with slight pressure turn counter clockwise - yes counter clockwise. You will feel the chown drop when the threads line up. Do not release the pressure and with your thumb turn clockwise. If you follow this you will never cross thread.

Ah so this is a common problem then and I should not be worried? The threads appear to be fine to my eye btw. Thanks for the advice, it does make sense I will try that!

My crown on my Invicta, the thread was super dry and had a little bit of dirt on it. I put some grease (tiny tiny bit) on the thread, and I cleaned it. Now the crown goes in smooth. Before, since my 8926OB was the first watch I had with the screw down crown fuction. I didn't apply any small bits of pressure while screwing in. I just let the crown move into the thread, that's how I cross threaded it. Thank god everything is fine now.

Sounds like you are fine now and I would not worry about it. You will know if you continue to have an issue in the future

I don't think that you did anything to the threads..

I think that the stem simpy caught on one of the pinions or detents inside the case and didn't move down far enough for the threads to catch..

That stem needs to engage and dis-engage a lot of stuff on it's way up and down, depending on the function that you are asking it to do...

This happens on my sub-c sometimes too. Especially when stopping the watch - sometimes when I try it just doesn't make that "click" and the watch continues to run and I actually cannot adjust the date or the time. I have seen this on many Rolexes and you just have to reset the crown and try again. On my sub I blamed it on its newness.

Thanks a lot for that. This makes a lot of sense pertaining to my experience yesterday. Good to know other people know exactly what I mean too!
