Gorgeous black dial in near mint condition, same goes for the white sweep and sub hands, indices and Seiko applied logo. Day/Date display at 3 o'clock with English/Arabic texts. This reference is commonly referred to as the 'Black Panda' after it's silver/ grey sub dialed cousin. Interestingly the 6138 movement was actually the successor of the 6139 (now widely accepted as the first automatic chronograph brought to market in 1969) and watches featuring both movements were produced in parallel until circa 1978 when both were discontinued. A useful feature of the 6138 is that unlike their 6139 cousins they can be hand-wound. comes on its original two tone bracelet with Seiko signed clasp.The movement is clean, free of any deterioration and keeping great vintage time.
