<Details of the original model>

On November 16, 1973, NASA astronaut William Pogue had this watch in the pocket of his spacesuit when he boarded the Saturn rocket.

The watch was one of the world's first automatic chronographs, the Caliber 6139 Seiko "Five Sports Speed ​​Timer" series, which Seiko began selling in the spring of 1969.

Pogue bought it at a store in the air force base for $71 at the time.

Seiko watches were not officially approved by NASA.

However, when flight training began, astronauts had not yet been issued officially approved watches, so Pogue wore a Seiko watch during flight training.

"I found that this Seiko was very useful when using the rotating bezel to measure the combustion time of the rocket engine."

Pogue thought, "I would like to use a Seiko in space," and decided to take it with him on the mission as his personal item.

And while on the space station, he wore a NASA-approved watch on his right wrist and a Seiko on his left wrist.

It was said that the watch showed accurate time even in zero gravity, even though it did not have specifications to withstand the space environment.

The watch that Pogue chose had a bright yellow dial, and even though it has been on the market for nearly 50 years, its vivid design still looks timeless and still shines with charm.

During the Skylab 4 mission, Pogue orbited the Earth 1,214 times and successfully completed his mission on the space station for 84 days, the longest time in space at the time.

Pogue continued to wear the watch for a long time after he took off his space suit, and in 2008, he decided to auction it.

He donated the entire amount of the winning bid to the Astronaut Scholarship Foundation.
