Omega Seamaster caliber 321 dating to 1965 with an unpolished original case and original dial. The 35mm. stainless steel case with protruding original pushers looks great. I love the patina on the original dial. The hands are also original. This watch even comes with the original Omega stainless steel buckle. We have not cleaned the movement, but it is accurate and the chronograph is functioning perfectly. These 321 chronographs are becoming hard to find.
