Serviced, NOS like condition, 1972 JDM Seiko Chronograph "Jumbo".
Caseback still has some protective film on.
It is a really good looking watch, but as it's nickname indacetes, it is quite large and I wouldn't recommend for anyone with wrist smaller than 17cm.
Movement has been serviced and it runs with strong amplitude and good accuracy. All buttons and crown operations work as they should, smooth, snappy and precise. Unlike 6139, caliber 6138 has manual winding and minute and hour recorder hands. Weekdays are in English and Kanji.
