Black dial 6139-7080 'Hexagon' Automatic Chronograph from October 1975. All original, serviced & with original solid link tapered stainless steel bracelet.
Manufactured by the Suwa factory in October 1975 and fully serviced. Keeping great vintage time. Automatic chronograph with a single thirty minute register at 6 o’clock and internal non rotating bezel with tachymetre scale. Chronometer functions all working as they should, buttons click nice and firmly and it resets perfectly to zero. Day/Date functions working correctly by pushing in the crown lightly for date and more firmly for day of the week.
7120 'T' dial in great unmarked condition. This is a great original example with loads of character and would make a great daily wearer. Unfortunately the case does show some evidence of polishing but still retains its lines. The case-back is unpolished & all markings are all clearly legible.
