SOLD — Seiko 6117-6410 Pepsi Navi-Timer GMT



For your consideration is an April 1973 6117-6410 Pepsi  Navigator-Timer GMT Automatic Wristwatch — Seiko’s answer to the Rolex GMT-Master. All components are original to the watch, including the uncracked factory plexiglass crystal. It comes on a new Uncle Seiko high-polish railroad.


The watch presents as very original unto itself and I would rate the cosmetic condition excellent. The case has not been polished and thus retains its original lines and the original brushing on the upper surface. The hands and dial surfaces are in flawless condition and retain their perfect and original lume. The dial and caseback are within a reasonable gap of 5 months (see images). These are extremely comfortable watches with a very elegant proportions and wrist presence.


Diameter: 41mm
Width (L-to-L): 45mm
Thickness: 12mm
Lug size: 19mm
Jewels: 17 factory plus 2 additional
