For sale is my Seiko 6117-6410 Navigator Timer GMT (Proof/Proof) from March 1970, with 6117B movement featuring hacking and quick-set date.

Internal 24hr bezel rotates smoothly. Domed acrylic crystal is in good shape and the chapter ring and GMT hand are free of paint loss. Case and OEM railroad bracelet show surface wear consistent with a 50+ year old sports watch. Service history unknown but running about -6s/day dial up (as with all vintage watches, YMMV).

Case measures 41mm x 45mm with 20mm lug width. Bracelet will fit up to ~7.5 inch wrist.

$475 shipped to US only. Payment via Zelle, PayPal F/F, or Venmo. No trades, please.
I've had 500+ good transactions on this and other watch forums and eBay feedback is available under the same username (where I've had 2000+ positive transactions). No returns unless the condition of the watch is materially misrepresented.
