I am looking for a 1958 constellation with arrow markers and just found an online shop selling one. I am not an Omega expert so I can't be sure if every part is original and coeval, if dial is not refinished, etc so I am posting here some pics asking for our comments/advices (I have no pics of movement). A last question, if it was all original and ok, how much would be a fair price to pay for it? Thank you very much.
