Among the most iconic chronographs of the 20th century, the Seiko 6139 Pogue holds a special place in both space and watch history. Named after astronaut Col. William Pogue, who famously wore a yellow dialed version aboard Skylab 4 in 1973, it was Seiko’s answer to the automatic chronograph race and one of the earliest to feature both a vertical clutch and column wheel.

This particular example, dated to 1975, started life with a metallic blue dial. Over time, it’s gracefully aged into a matte charcoal tone. Something to be described as a completely natural and highly desirable shift. All original components remain intact, including the bright orange chronograph hand, inner tachymeter bezel, and fading Pepsi outer bezel. This example belongs to the second generation of Pogue's of which omitted the “Water 70 Resist” marking due to sealing issues discovered in earlier references. A detail that adds both historical context and functional clarity.

Recently serviced, this example runs smoothly with functioning chrono and quickset date. A Seiko H-link bracelet (replacement clasp) will be included, however it currently sits aboard an eye catching denim strap. To this day the Pogue remains a gateway for many collectors and  lifelong keeper for others. Part tool watch, part space relic, all character. The Pogue doesn’t just tell time, it tells a story.
