Serviced, 1976 JDM Seiko 5 Sports SpeedTimer "BullHead", 23 jewels automatic chronograph with manual winding, on original bracelet.
Original dial and hands are in great condition.
Case is sharp, cloth buffed only, so there are some small nicks and scratches, but overall in pretty good condition.
Original stainless steel bracelet is in good condition. With Seiko spring loaded, retractable clasp extender fits up to 18.5cm wrist.
New crystal and all new gaskets.
Movement has been serviced and it runs strong with good accuracy. All buttons and crown operations work as they should. Unlike 6139, caliber 6138 has manual winding and minute and hour recorder hands. Weekdays are in English and Kanji.
