Vintage Omega

I was walking around Bangkok this afternoon and there are not many vintage watches around. Found this solid gold Omega in reasonable condition but I have resisted in buying as I am trying to streamline and refine my collection,

During the past few months, I have branched out to the IWC collection and Military watches but I have since let go the IWC and focus on the vintage military and Rolexes. The only exception was the large Gubelin automatic Moonphase which is quite a rare find. 

I am hoping to find a Rolex green sub 50th anniversary...
