This watch was the subject of a recent video about Seiko’s 1980s quartz tech.

• Watch is entirely serviced, and dialed in very tightly to a few thousandths of a second per day accuracy

• All lume original, slightly greyed

• Hand surfaces are excellent

• Case shows wear, but all sealing surfaces are excellent

• All new seals (these are rare and basically impossible to find now, rotating ring gasket especially)

• Crystal is original as replacements are impossible for me to find. There are some scratches / marks

• 19mm lugs.

• Kanji / English daywheel.
