1976 Seiko 5 Sports SpeedTimer 6139-8040

 Overhauled 1976 JDM Seiko 5 Sports SpeedTimer automatic chronograph in very good condition. 

All original except for the bracelet and gaskets. 

Beautiful blue dial has no noticeable flaws. 

Case has few small nicks and scratches noticeable in pictures, but in person they are barely noticeable. It is sharp and edgy. 

Original crystal has one small scratch, but it's not noticeable with naked eye. 

On a very good quality, vintage Top, solid link stainless steel bracelet. It fits comfortably 17.5cm wrist. 

The movement, being JDM, has 21 jewels as opposed to overseas models that are severely under jeweled with only 17. It's been well maintained and after service it runs with solid amplitude and good accuracy. 

Crown and pusher operation is smooth and easy. New gaskets on everything. 

Calendar quick set works by pushing the crown. Weekdays are in English and Kanji.
