Hello-
I own the watch described in the subject.
When changing the band recently, the bezel popped off. I was able to press it back on, albiet it took a little bit of effort.
I plan on taking it to a watchmaker for repair, I just wanted to understand what would/could have caused this to happen and what parts would be needed to
repair this. The bezel rotates in order to do calculations for aviation. Pictured is a photo of the watch I have ( not mine, but identical model, poor band color choice).
Best
Samson
