Serviced, 1977 JDM Seiko 5 Sports SpeedTimer "BullHead", 23 jewels automatic chronograph with manual winding in nice condition.
Apart from the new crystal, everything is original.
Case is polished, but it's done nicely and lines are kept sharp.
Dial has some small blemishes, but nothing too noticeable with naked eye.
Hands are relumed.
Original, fishbone stainless steel bracelet is in good condition. It fits up to 17cm wrist. I have aftermarket links that look and fit like original and can be added for desired length.
Movement has been serviced and it runs with strong amplitude and good accuracy. All buttons and crown operations work as they should. Snapy and precise. Unlike 6139, caliber 6138 has manual winding and minute and hour recorder hands. Weekdays are in English and Kanji.
New crystal and new rubber gaskets on the crown, pushers and caseback.
