It's 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. Even during the present day, in the era of the smart phone, there exists a certain charisma to the GMT watch – like this early 1972 Seiko 6117-6410 Navigator Timer automatic GMT on offer here – that appeals to vintage watch aficionados. Of significant note, this all original 6117 GMT comes with ALL of its original paperwork (to include its purchase receipt, Seiko 6117 GMT instruction manual, Seiko guarentee card, and Seiko dealer card) and original Seiko bracelet. All serial numbers match throughout the paperwork. Per its receipt, this 6117 was sold by a Hong Kong-based dealer in September 1972 - and, you guessed it, we bought it from its original owner. While the original crystal has small scratches, we left it in place to keep this 6117 GMT fully original - but we can replace it with a new Seiko-correct one if the buyer wishes. The 6117’s independent GMT red time zone hand (see pictures) is used in coordination with the inner rotating bezel to tell time in another time zone of the wearer’s choice. The wearer simply sets the inner bezel to the time they desire (ie: GMT is four hours ahead of EDT, so the inner bezel is set four hours ahead of EDT time), and the red hand moves along with the regular hour/minute hands. It’s important to note that the red 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. On the inner bezel are red and blue segments – indicating 12 hours of daylight – red – and 12 hours of darkness – blue! The 6117’s independent GMT red time zone hand is used in coordination with the inner rotating bezel to tell time in another time zone of the wearer’s choice. The wearer sets the inner bezel to the time they desire (ie: GMT is four hours ahead of the U.S.’s EDT/EST, so the inner bezel is set four hours ahead of this time), and the red hand moves along with the regular hour/minute hands. This Seiko 6117 comes with its original stainless-steel bracelet, nylon "seatbelt" NATO strap, Pelican travel case, and springbar tool.
