The watch has been in our family as long as my mom can remember (40 years or so). It looks like a De Ville, but I cannot find any on Google images that are an exact match. Can anyone here help? Thanks! Anthony
It's a generic (no series name, as in Seamaster or Geneve) manual wind from the 60's judging by the bezel and dial pattern.
It's indeed a one shell case. I reckon it will look a helluva lot better if you polywatch that crystal and attach a nice strap to it. Nice watch!
I think it belongs in the series "Omega Slim" from the early to mid sixties. http://www.old-omegas.com/catuk64.html This is close but lacks the subsecond and does not have the same textured dial. http://www.old-omegas.com/pics/catuk64/p33.jpg
I think it's a snap back . Not a front loader . It's gold . 18K or 14K . Looking very much like this http://timerecs.com/inf/37519-vintage_omega_ultra_slim_14k_solid_yellow_gold_mens_watch.html
