Seiko's third iteration of a "world time" design came in the form of the 6400. It was available in a few differing color ways, but for us, the black and orange variant is certainly the list topper. The dial is a rich charcoal black with a linen texture, and a crisp lacquer finish. At its edge is a pumpkin orange 24 hour track that can be used in conjunction with the black and orange "cities of the world" inner bezel to determine the time anywhere in the world at a glance. The hands and applied markers are brightly polished aside from the bold red of the contoured GMT hand. The case offers great vintage appeal through its tonneau style architecture and large 41mm diameter. The crown is set flush against the case, and in the neutral position can be turned in either direction to rotate the inner bezel. This example from August of ‘71 is completely original, beautifully preserved, and an incredible bang for your “World Time” buck. The 6117B is a workhorse calibre that’s built to last, has hacking seconds, and offers fantastic value, all neatly packed into one of the coolest looking watches to have come out of the era.
