Seiko's sophomore attempt at a pilot's watch came in the form of the 6117-6410. Carrying the same name as its predecessor, this Navigator Timer is a classically designed GMT with several points of improvement over the former. With a broader tonneau style case, the 24 hour bezel has been repositioned to frame the dial inside the case, and is split into two segmented halves: red for daylight hours, and blue for night. The colors are vivid and free of any fading or paint loss. Rotated by the crown rather than as an exterior bezel, it is less likely to be jarred out of position. The dial is perfect, and in a matte black, is contrasted for legibility by long and sizable white luminous markers. Tracking a second time zone is made easy by the "dog-legged" and bright red, fixed 24 hour hand. The 6117B adds a hacking lever not available on the first model, and is a robust and reliable caliber built for durability. This "Proof” dial example from November of ‘69 is an absolute stunner, and one of the earliest produced. It’s completely original other than a replacement crystal, and post service, it’s keeping near perfect time. For a true to form finish, we’ve paired it with a heavy RAF NATO in a rich steel gray. Comfortable on the wrist, and up for any occasion, this GMT is a lesson in timeless styling and versatility.
