I've recently found this vintage Omega in my dad's collection. I'm not sure about the origins or anything at all about it.
1. Is it authentic?
2. What model/line/series of Omega is it? (e.g. Seamaster, Constellation, Deville?)
3. What is the period is it from? 1950s, 60s, 70s?
It has an extreme tropical dial and the lume on the hands have fallen off.
Any opinions are greatly appreciated. I have no clue whatsoever. Cheers.
