New guy -- Lady's 1969 DeVille

Back again with another new old watch. Bought this at the Navy Exchange in GITMO for my wife's birthday in (about) 1969. (Could have been 1970.) It's been retired for quite a while, but I'm planning to resurrect it along with my even older Rolex Explorer (1968) and Omega Seamaster (another earlier thread). Would welcome any thoughts or suggestions from this august and friendly group and thank you again for all the replies on the Seamaster.
