The Seiko 6139 "Silver Pogue" automatic chronograph – a historical movement in its own right, like this just serviced 1977 Seiko 6139-6002 here – was one of the first automatic chronographs created and ranks with Zenith’s El Primero and Heuer’s Calibre 11. 


Back in the late 1960's, Heuer and Zenith had taken hold of the entire sports watch industry by racing to become the first to produce an automatic chronograph. It has been widely debated who won, but in the background of this skirmish, Seiko quietly created their own at the same time,  beating the Swiss at their own game – the Seiko 6139.

We all know Omega was the first watch on the moon, mostly because Omega won’t let us forget (ever).  However, the first automatic chronograph in space was the more humble and less publicized Seiko 6139-6005, named after US astronaut Colonel William Pogue, who wore his on the 1973 Skylab 4 mission-despite not obtaining NASA authorization–to time shuttle engine burns due to his familiarity with the watch and trust in its capabilities…trusting the lives of himself and fellow astronauts to the reliability of his Seiko!  When asked about his 6139, Pogue confirmed the story and sold his in a 2008 charity auction for an amazing $6k!

The 6139 was the first chronograph to have a vertical clutch, a feature considered to be one of the hallmarks of a superior automatic chronograph movement.  The 6139 features an automatic column wheel timing control and an integrated chronograph, which means the entire movement was designed and built to be a chronograph, vice being an automatic movement with a mere timing module.  The 6139 movement features a single register chronograph allowing time to be measured in increments of 30 minutes.


This "silver Pogue" comes with a leather rally strap, NATO strap, Pelican travel case, and springbar tool.
