Look at this fine 1966 35mm stainless steel Omega Constellation having baton steel markers and matching hands, date aperture, and a polished screw-back case having the raised observatory logo! The silver dial is completely original and flawless! Please note that this watch looks even larger than 35mm due to the all-dial appearance and narrow bezel! The original flat recessed Omega winding crown is still intact. The automatic winding caliber 563 Omega movement was just cleaned and is keeping accurate time. Overall, this is a splendid example of a fine Omega Constellation!
