Need Crown Help/advice On 5218-201...

[longshot]

i am almost ready to conclude i was never meant to own a 5218

it took three tries and a couple months to finally get a good one from davidsen. the one i have runs a but fast but didn't have any of the other qc issues and the 5201 and 036 are my favorite pams.

then last night i took it out of my watch box to put it on and noticed the crown just spun?

it looks like it's no longer attached to the stem and if i took the crown guard off it would just fall off. the crown on this one never did have as good a feel as my 036 but it did wind and set ok.

my question is; how hard is it to re-attach it? while i am mechanical i honestly leave a lot to be desired in the manual dexterity and vision departments

i am assuming it just screws on to the stem (reverse thread?) and if that's all it is i could probably do it myself. if it's more than that i do have a local watchmaker who will work on reps but he is closed weekends, and across town and dropping it off would eat up an entire lunch hour.

any suggestions or advice would be greatly appreciated
