• Movement upgraded with a 35-jewel Seiko 6218a, fully serviced

• Also comes with its original 6217a movement

• Case in good original polish with good case lines and clear brushing. No big dinks, just the wear you see with a working watch.

• Caseback is the dolphin variant, worn fairly smooth but still legible. Caseback has some tool marks.

• Dial lume is original and shows evidence of moisture intrusion

• Markers also show signs of moisture intrusion, with a frosted effect to the tops.

• NOS hands are genuine Seiko, Daini-made, with the correct green lume.

• Case has no pitting or corrosion damage

• Crown rebuilt with a new gasket

• Crystal is the original; it has some crazing but I think it looks great so I left it.
