All, I have been offered a vintage Piaget watch for €600 but no idea how to know if fake or real. Woudl anyone have an opinion based on pictures attached- its supposed to be 18ct gold 1960s with just the strap changes from original. No warranty card with it but can see serial number etc. I love the watch as have a slim wrist sand this is 5mm depth and 34mm case size. Thanks!
