Hi all! I recently stumbled across this really attractive WW2 Longines watch on eBay. I wanted to hear everyone's thoughts on it. The seller hasn't provided any information on whether the crown/crystal is original (though in the listing has said that the dial is original). I'm not sure if the crown is original, since many WW2 watches seem to have a bigger crown. Thoughts on the crown/dial/crystal and the watch in general?
