Hi Forum Folks! I am looking at a watch that's on an auction, and I do need your help here. The auction house states this a 145.012-66, but I don't think they have a clue? Here is the description from them: OMEGA Speedmaster ref.145.012-66 circa 1966 Steel bracelet chronograph watch. Round case with lyre handles (Huguenin frères) with external tachymetric bezel and "Don" insert. Screw-down caseback with Speedmaster logo. Signed crown. Dust cover. Anyway.. It has a 321 movement, and the serial nr is in the right period. The pictures shows the caseback with a CB stamp, but the pictures of the watch doesn't (in my opinion) show the facet line on the lugs.. Could these have been shaved down, or is the casebook from another watch?? I know that the condition isn't top, but it would be a nice daily beater maybe? But I need som help with this one! What do you guys think?
