If there is one thing to remember forever in collecting vintage omegas, it is that condition is first and foremost. Of course the piece has to be original in the first place but if there is one lesson that has been imparted to me and one I wish to pass on it is that. As I have stated in another thread, it is far better to overpay for an excellent original vintage omega than to underpay for one in below average or average condition. My greatest regrets in this hobby have been not overpaying for excellent examples - if only I could raise my offer some more for these long gone and in many cases never to be seen for sale again examples. Other rules I TRY to live by: Better to have 1 excellent piece than 3-4 so-so ones. Never sell to a dealer - you will never get close to what your watch is worth. Ebay is the best place to get nice vintage omegas at reasonable prices IF and only IF you have the knowledge and patience to sift through the many many crappy pieces. If you do not know the seller always pay via paypal using your credit card - that way you will have some recourse if the deal goes wrong - and if you do enough deals something will inevitably not go your way. You should have 1 or 2 trusted watchmakers preferably someone local. And when you have something repaired be explicit about what you want done and not done - I attach an index card with written instructions for every watch I have serviced - want to make sure everything is crystal clear.
