Hi all, Could you help me with an advice on this Longines - is it authentic or franken and do you spot any general flaws (other than the patina on the dial which I don't mind in this case)? I notice that the caliber is 19AS which seems pretty common and the model is 2030 SW. Unfortunately, could not find similar items with that number while browsing online. Does anyone also has an idea of the pricing of such piece? Couldn't find past auctions on ebay of similar items.. Many thanks!
