The world of horology is full of milestones, but few are as awe-inspiring as those linked to space exploration. Among the select few timepieces that have left Earth’s atmosphere, the Seiko 6139-6002, affectionately known as the Seiko Pogue, holds a unique distinction: it was the first automatic chronograph to venture into space.
The Backstory: William Pogue’s Iconic Choice
In 1973, NASA astronaut Colonel William R. Pogue embarked on the Skylab 4 mission, a 16-week scientific expedition aboard America’s first space station. While NASA issued the Omega Speedmaster as the standard-issue watch for astronauts, Pogue brought along his personal Seiko 6139-6002—a bold, colorful chronograph he had used during rigorous pre-mission training sessions.
Pogue had tested the Seiko’s reliability during intensive simulations, and it became his trusted companion. Though not officially NASA-certified, the Seiko accompanied him to space as a secondary timepiece. Its yellow-gold dial, combined with its durable automatic movement, made it a standout both aesthetically and technically.
What Made the Seiko Pogue Special?
The Seiko 6139, introduced in 1969, was among the first automatic chronographs ever produced, representing a breakthrough in watchmaking. Here’s what made it extraordinary:
Caliber 6139 Movement: A robust, column-wheel automatic chronograph movement with a quick-set day and date complication.
Distinctive Design: Its vibrant yellow-gold dial earned it the nickname “Pogue.” Other versions featured dials in blue or silver, but the yellow variant became iconic.
Rotating Tachymeter Bezel: A practical tool for timing and speed calculations, which added to its utility.
Unmatched Durability: The Seiko Pogue proved its toughness during the extreme conditions of space, a testament to its reliability.
Why Did Pogue Choose the Seiko?
Before the Skylab 4 mission, Pogue purchased the Seiko 6139 for $71.50 from a PX store. He relied on it for its stopwatch functions during pre-flight tests. When the mission began, the Seiko became his backup, as the Omega Speedmaster remained the official watch for EVA (extravehicular activity) tasks.
What’s fascinating is that Pogue wore the Seiko on his left wrist throughout the mission, making it the first automatic chronograph to orbit the Earth. Its flawless performance during the mission cemented its place in horological history.
A Coveted Collector’s Piece
The Seiko Pogue’s journey into space has turned it into a highly sought-after timepiece for collectors. Its value has skyrocketed over the years, with well-preserved models often fetching thousands of dollars in the vintage watch market. What makes it even more desirable is its connection to both horology and space exploration—a combination that few watches can boast.
The Legacy of the Seiko Pogue
The Pogue’s story is a reminder of the ingenuity of 20th-century watchmaking and the enduring human spirit of exploration. It also showcases the innovation of Seiko, a brand that defied conventions and created a watch capable of performing in one of the harshest environments imaginable.
Today, the Seiko Pogue represents more than just a watch—it’s a piece of history, a symbol of courage, and a testament to the pioneering spirit of both astronauts and watchmakers.
