Hello, I have an old pocket watch that I would like to find out more about. All I know about it is that my grandfather brought it back from WWII with him. I have a watch smith look at it and it still works although some maintenance/cleaning is required. There's not a lot of information available online, but I believe this was a swiss made watch (indicated on the face) from a company based in Porrentruy, Switzerland. I did come across a mention that this was a watch/brand given to German army officers from 1938-1944 so I assume this particular watch may have been made around then. It has a beautiful gold trim/backing and I believe the crystal cover is now plastic and it has yellowed over the years. I would greatly appreciate any information pertaining to it's history and rarity.
