Hi,
I bought this watch a couple of months ago. According to the seller it was NOS, so I had it serviced. Now I have discovered that another member of the Swedish forum Klocksnack.se also has a Bund but on his watch it is a serial number between one pair of the lugs and the model number (1550 SG) between the other pair of lugs. I have neither on my watch... I have tried to figure out whether it is something wrong with the watch or not but unfortunately I haven't enough knowledge so I can't see anything fishy besides the numbers. Needles to say, it is important for me to know. I don't want to risk selling a watch that is not legit.
I would very much appreciate your help.
