Serviced, 1976 JDM Seiko 5 Sports SpeedTimer "BullHead", 23 jewels automatic chronograph with manual winding in nice condition.
Original dial and hands are in great condition.
Case is polished.
Bezel insert has faded a bit, probably due to excessive sun exposure.
New aftermarket fishbone (like the original) stainless steel bracelet with genuine Seiko clasp. Sized to 17.5cm with two extra links.
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.
