I have a very nice Marathon GSAR automatic watch for sale/trade. This is the US Government marked version. Tritium is still burning very bright. Has a couple SMALL dings/marks on bezel, I wear it everyday. Asking $550. Look on eBay if you think this is high. Includes box and 3 or 4 NATO or Zulu style straps. I am upgrading to a Breitling or Omega, so this will just sit in the safe. Firearms trade offers welcome.
