During the present day in the era of the smart phone, there exists a certain charisma to the GMT/Navigator watch – like the 1969 Seiko 6117-8000 Navigator Timer GMT automatic here, on its rare original "ladder" bracelet – that appeals to vintage watch aficionados. 


It is not always immediately obvious why particular complications find their way onto the mechanical wristwatch that might be viewed as indispensable, but for the air traveler, international corporate executive, news, finance, or communications personnel of the 1960’s, a watch with a 24-hour function must have carried a certain useful appeal.

The 6117 is of a similar movement pedigree to the famous Seiko 6105 diver, with the rather notable exception that the 6117 possess a date register and a third 24-hour GMT hand calibrated to the main hour hand, and an inner bezel.  And we can't fail to mention the 6117 Navigator Timer was Seiko’s second GMT watch after their World Timer.


The Seiko 6117 GMT here also features a gunmetal grey dial, a bright-red GMT hand, lumed hour and minute hands, and a lightly lumed chapter ring that makes for a highly functional GMT watch that was a favorite of Viet Nam War pilots.

It’s important to note the red GMT - GMT being four hours ahead of the U.S.’s EDT/EST - hand only makes a complete circle of the dial every 24 hours (the hour, minute, and separate time zone red hand all align at the 12 o’clock position when this occurs), so it moves more slowly than the hour hand.

This Seiko 6117 comes on its original bracelet, and with a nylon strap, rugged travel case, and springbar tool.
