SOLD — Seiko 6117-8000 Navi-Timer GMT



For your consideration is an April 1968 6117-8000 “Proof-Proof” Pilot’s GMT Automatic Wristwatch. The very first Seiko 6117 GMT.


The watch presents as very original unto itself and I would rate the cosmetic condition as a 9.8/10. The case has not been polished and thus retains its original lines and the original brushing on the upper surface. The hands are in extremely good condition and both the dial and all hands retain their original lume. The watch comes on a vintage Speidel “Corfam Suede” tapered band.


Diameter: 38mm
Width (L-to-L): 45mm
Thickness: 12mm
Lug size: 19mm

I serviced this watch on 07/30/2021. That process includes a full cleaning and evaluation of all movement components and proper lubrication. Lubricants used were Moebius synthetic varieties appropriate for this watch movement type. The dial date is (82), and within two of case back date (84). The movement now has two custom produced, American made jewels in the ports of the barrel arbor. The amplitude of the balance wheel is 230-240 range and the rate is (+/-) 2 sec/day. The case back and crown all have new, and factory correct seals and it has a new acrylic crystal. This watch comes with a 100% money back promise of originality and a 1-year limited warranty on the movement from the time of sale.
