I have a Marathon Steel Navigator (SSNAV-D) in exceptional condition for sale. This is the new version with the extremely accurate ETA quartz movement which is accurate to approx. 10 sec/year. Worn sparingly in rotation with other watches. I honestly cannot see any marks on the case other than light polishing on the case back from the single pass velcro strap I had it on. It will come on the original single pass military style "Ballistic" strap it came with which is unused. All functions work as they should. Excellent bezel action. Tritium lume burns bright and is very legible all night long. Original box and documents included. I am looking for a domestic (USA) sale, no trades. $525 (firm) shipped CONUS. Paypal F&F or Venmo. Paypal G&S OK but buyer to cover fees.
