I found this watch after clearing out old stuff that was taking space. As I remember my grandfather gave it to me in the 80s when he got a new one.
So Im guessing its mid 70s or early 80s.
It says edox delfin on the face, and on the back it says swiss made 200572 superwaterproof 20 atm shockprotected.
I have not opened it, but it runs and feels like manual wind.
