The Seiko 6139 automatic chronograph a historical movement in its own right, like this full serviced mid-1969 Seiko 6139-6000 "Cevert" proof/proof here, w/its original H-link bracelet – 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.

 

Those who know vintage Seiko - in particular 6139 chronograph's - know these early 6139 proof/proof's come up for sale rarely.


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


With this movement, Seiko set the standard, which was followed by the Swiss watch industries 20 years later. The same movement configuration was adopted by Rolex when it made its own in-house movement for the Daytona in 2000, 30 years after Seiko released the caliber 6139 and 6138.

 

This 6139 includes its original stainless-steel bracelet, nylon NATO strap, springbar tool, and Pelican travel case.
