I picked up this watch the other day at a flea market. I think I have gleaned website That it was a Swiss make but a German product? That the inscription under the back is “cylinder” meaning the type of movement? And the number of jewels used in making it? I also made sure to include clear pictures The markings on the rim of the inside cover I thought might’ve been damage from opening it up, but both markings match each other exactly so I’m thinking that’s not the case. Any input would be greatly appreciated. Thank you!
