Seiko 6458-600A JDM mid-sized diver, fully serviced
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
Kanji / English daywheel.
