Recently I inherited a watch from my grandmother that was my grandfather's. He bought in the late 60's from a gambling man. The inside of the case has lots of numbers written all over it none of which I can really make out.
My first question is what these numbers represent.
The back of the watch mechanism says "17 Jewels, Unadjusted Swiss M5" It has 10 CL inside a rectangle.
It is a Bulova, Has a square face and 32 Diamonds on the face. I think it originally had a black faceplate, my grandfather changed it to a gold one because it was easier for him to read.
I basically want to find out as much about the watch as possible. I will include some pictures.
Thank you in advance for any help offered.
