Hi, i need help identifimg this watch: http://magicka.hyves.nl/album/54810999/Iedereen//fotos/1377881346/0/z67m/ i'm told it's a 1940's JLC Automatic Caliber 481 Power Reserve. 10K gold filled case and back and original 10K GF strechband. From the look i think it's authentic (also because the back is engraved with a firmname for 30 years of service and i dont think a firm would give a fake). What could be the worth of this watch? Can it be a fake? What is puzzling me is that i cannot find a same watch anywhere with the same dial. Thanks Stefan
