Done a few years past, but still applicable is my report of sources for fine old watch collectibles with resulting examples. Still have most of these, but a couple financed quite a few other good purchases. The Lemania actually came from owner's modest estate sale and Patek from owner's friend. Thus all from different kinds of sources. No collectors or watch dealers. Craigs list and ebay are possibles but so far for me have not been cheap sources for good stuff. Just had to do complete computer recovery because of an ebay listing of a 50th anniversary gruen. Got thru firewall and a refreshed Norton. Massive virus from someone mad at ebay?
