I am looking at a beautiful Vulcain from the 60's. From what I have read these watches have always been associated with a Swiss company. However the site has the following in the descriptionI am a little confused by this as the dial has 'Swiss Made' on it. Can anyone shed some light on this?1960's Vulcain Base Gold Color Metal and Stainless Steel Back with Original Dial. Triple Signed. Hong Kong.
