Nikos makes a valid point. to buy pre-owned or vintage without doing any homework would be wreckless, i bought my 1st Rolex 5/6 years ago but i'm still learning now & when searching for my Red 1680 i spent close to a year reading all i could find to arm myself with as much knowledge as possible. knowing what questions to ask is ok but knowing how to identify original parts yourself is far better, plus you'll spend more time on TRF & having a laugh while you learn too....bonus
