Stainless steel case 150m waterproof 1st professional diver from Seiko, launched in 1965.
The watch is in excellent conditions overall, with its dolphin backcase, the big signed crown and rotating bezel. The sunburst dial is still spectacular, a joy to watch everytime the light changes. Matching green patina on hands and dial, and the small cracks on the original glass are truly the icing on the cake.
38mm without crown.
