Help with info - older Seamaster Deville

I'm looking for whatever other information I can find out about this watch. Any information such as age and approx value would be great (so we know does it stay in the dresser or get moved to the safe). It is my dad's watch and was apparently given to his dad by whatever company he worked for at the time as either some sort of anniversary or retirement gift. I can get more pictures next month but these are the pictures I have currently.

I've done some digging through here and based on what I've been told about the watch and the DeVille name I'm guessing 60's or early 70's - but I'd be grateful for anything else anyone knows.

As far as I know Seamaster Deville was produced 62-66. Deville was after 1967 own sub marque as Seamaster or Constellation. Seamaster was taken away from the dial.

I think they are a lot of articels on SM De Ville if one searchs with google…
