··Vintage Omega AficionadoI would add that there are new vintage collectors raising in the new middle class developing countries, especially in Asia. China, India, Indonesia, Korea, Singapore, Thailand, Phillipine, Vietnam, MIddles east , etc. (well I am included).
Rolex, Omega and Breitling probably a no brainer choice for them because of the current marketing sexiness. It is also relatively affordable and available, unlike Patek or Breguet world. Sooner or later these new collectors are looking for similar highly collectible item from 50's and 60's.
Availability of vintage Omega in this market is miniscule, because during 50's and 60's, Omega is only for royalties and riches. With the advent of internet trading, the Asian collectors and traders are scouring Europe, US and probably Latin America to feed their highly collectible demand.
So the developed world 'collector holes' + new developing countries 'collector holes' + no more supply of this vintage watch = meaning it would be only one direction = scarcer and pricier. Of course there would be some bubbles (like Omegamania) here and there.
Not to mention that it is in those same developing markets that the modern omega brand is surging in popularity adding more fuel to the demand for vintage omega watches.
