i would like to somebody help me to identify this i belive swiss chrono watch, or at least the movement.
It is a single button chrono, by movement similar to venus 175, or landeron 39?
I know it is hard, couse the face of the watch is in bad shape and it is not branded.
Also i would like to know what is the mark on the backplate P.B. means?
It has a serial number also if it helps.
