I'm trying to identify this watch that belonged to my mum. I'm sure its at least 30 years old as I remember it when i was a kid, but is it older than that? It's quite heavy, but I'm not sure what the bracelet/strap is made out of - i couldn't find any hallmarks, but i could just make out the word microns, and that is it.
There is a serial number on the back of the watch - see pics, and all it says on the face is Baume.
