I am new to this board a was wondering if I could some help in dating my "new to me seamaster deville". I found it at a local shop in pristine condition. The Watch keeps very good time, +\- a second or 2 a day. What I would like to find out the approximate age. The date can be changed by pulling the stem all the way out if that is an indicator. I will add an image in a later post. Thanks!
