Hi, I’m new to the forum and seeking your advice on buying my first vintage Omega Seamaster. What I’m currently looking at: Reference number: 166.032 Caliber: 751 According to the seller it’s non polished, crown’s original, last service in 2017. Selling price: $ 850 Unfortunately no high resolution pictures available, sorry. What do you think, is it legit? Thankful for any advice. Regards, J
