UK vintage help please :).

[Danielmp007]

So Iv had a few issues with my sisters Tudor, that's off for servicing because it wouldn't wind. And now something similar has happened to my 2 tone DJ ��!

A couple of months ago I went to the Caribbean and changed the time. Upon changing the time my crown and stem came out, when I put it back in it didn't work but with about 20 seconds of wiggling in and out it started ticking again. Came back to the uk and changed the time back no problem.

This week I changed the time (lost a couple of minutes) and it came out again but won't tick again. I was gonna put it in for a service but I see you guys say a lot not to go to Rolex because they replace a lot of original parts? I live in the north of the U.K. So any help would be nice.

Also my bracelet is very "stretched", I see somebody in Hong Kong mention on here a lot but would rather uk help? Also I couldn't find the HK guy in searches.

Thanks guys
