Look at this very clean and unpolished 1966 Omega Constellation having an uncommon dual name original and very clean Turler dial. Turler was a European jeweler who retailed many high end watch brands. This watch has a 33.5mm. stainless case with sharp edges that looks larger on the wrist due to the all-dial, narrow bezel design. The very fine Omega caliber 712 automatic (chronometer grade) movement was just cleaned and is accurate. The correct Omega winding crown is still present. One of the best qualities of this vintage Omega is the thinness of the steel case-7.8mm. including the crystal.
