There exist numerous vintage Seiko divers popular with "Seikoholics" collectors, but none more so than the venerable 6309 series here - like this full serviced and all original 1980 Seiko 6309-7049 automatic diver.

 

The 6309 series of diving watches was the third generation of Seiko’s recreational/professional divers. The 6309 line replaced the 6105 in 1976 and was produced until 1988, when Seiko replaced it with the 7002 diver.  6309’s were a successful effort by Seiko to improve the 6105 movement, which allowed for greater lifespan, robustness, and ease of maintenance.

 

The 6309 line was produced in two separate case variations: an earlier cushion case, popularly known as the “turtle” for the appearance of its cushion case, which was produced between 1976-88 (making the 6309 on offer here one of the first produced by Seiko), and a slimmer case version from 1982-88. The 6309 was popular with the U.S. military, akin to the Seiko model it replaced, the 6105 - its (much more expensive) forefather - and quickly became the staple of the working diver.

 

The 7049 was designated for the North American market, and the 7040 was for the Japanese Domestic Market (JDM) and the rest of the world.

 

This Seiko 6309 diver comes with a rubber Z22 vent strap, nylon NATO strap, Pelican travel case, and springbar tool.
