All original except for crystal and the bracelet which has been replaced with a high quality Uncle Seiko designed specifically for this watch. This reference is often referred to as the blue Pogue after Colonel William Pogue who wore his own personal yellow dial 6139 on NASA's Skylab 4 mission in 1973, to read more about that please click here

More recently these blue dial 6139's are becoming known as the 'Cevert' after a photo emerged of the legendary and maverick French F1 driver François Cevert wearing his during a photo call in his car circa 1972. Tragically he was killed soon after in a crash during practice at Watkins Glen International in 1973. Many had tipped him as a future world champion, including his friend and mentor legendary driver Jackie Stewart. Cevert's death was the catalyst for Stewart launching his lifelong campaign to improve driver safety in motorsport. Another notable fan is Pink Floyd’s Nick Mason wore one too. Please click here to read more about Cevert, Mason and the history of this iconic watch.

Manufactured by the Suwa factory in July 1969 so a very early piece made for the Japanese Domestic Market. Keeping excellent vintage time. Automatic chronograph with a single thirty minute register at 6 o’clock and internal rotating bezel with tachymetre scale, operated via the crown. Chrono 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 day and more firmly for date. Cosmetically in excellent condition. Dial near perfect and only minor marking to the case and bezel.

Day/date turn over at midnight & quickset works as it should. Not guaranteed water resistant.
