Seiko "Coke Pogue" 5 Sports Speed-Timer (1971)

Model History

 

Introduced in 1969, the Seiko calibre 6139 was one of the world’s earliest automatic chronograph movements and the first to combine automatic winding with both a column wheel and a vertical clutch. This advanced construction enabled precise chronograph engagement and helped establish Seiko as an important innovator in mechanical chronograph development.

 

Reference 6139-6032 was produced for the Japanese market as part of the Seiko 5 Sports Speed-Timer collection. Its black dial, champagne-coloured 30-minute register and contrasting black-and-red tachymeter bezel have led collectors to nickname this distinctive version the “Coke Pogue”. The name refers to its connection with the wider 6139 family; Colonel William Pogue’s actual space-flown watch was the better-known yellow-dialled 6139-6005.

 

Manufactured in April 1971, this example represents an early and highly collectable version of the 6139-6032.

Condition

 

The watch is presented in attractive vintage condition and retains the bold, sporting appearance associated with the early Seiko Speed-Timer collection. The black dial provides strong contrast with the champagne-coloured chronograph register, applied hour markers, white hands and yellow central chronograph hand. The dial remains clearly legible and shows only light age-related marks. The luminous material on the hands and hour markers has developed a warm vintage tone.

 

The black-and-red external tachymeter bezel remains visually striking and clearly legible. It displays light scratches, surface wear and some age-related fading, particularly around the coloured sections. The internal rotating timing bezel also remains clearly presented and functions correctly.

 

The stainless-steel case shows scratches, small marks and normal signs of previous use consistent with its age. Its characteristic angular profile and contrasting brushed and polished surfaces remain well defined. The stainless-steel case back displays surface scratches, while the reference and serial numbers remain clearly legible.

 

A new, clear and scratch-free mineral crystal and a new aftermarket stainless-steel bracelet have been fitted. The bracelet accommodates wrists up to approximately 21.5 cm.

 

The Seiko 6139 automatic chronograph movement was fully serviced in May 2026. All functions are operating correctly. The chronograph starts, stops and resets as intended. A 6-month guarantee is provided on functionality from the date of purchase.
