SOLD – Seiko 6117-8000 Navi-Timer GMT



For your consideration is a September 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 8/10 as there is a minor degradation of the dial lacquer where the dial meets the chapter ring at 2:00 and 7:00. However, these two minuscule blemishes are very difficult to see. The case the original brushing on the upper surface and has not been polished; retaining all of its original case lines. 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.
