This is a West End Watch Co Sowar Prima, 1960s is what the seller indicated. It was running sporadically only and my watchmaker told me that rust on the movement made it not worth sinking any money into (I only paid £9 for it including shipping). As I like the dial and hands I'm wondering if I could swap out the movement? I haven't been able to find a signed West End movement to replace it with, but could i get an ETA movement to fit? I know this probably makes it a bit of a franken but looking for advice. Thanks!
