The markings on the back indicate that this is the commemorative version of the Mil-W-46374 watch that Benrus originally made for various militaries, including the US starting in 1975. If so, it features the 17j ETA 2801-2 movement. The military versions have the H3 and radiation symbols on the dial like the only Timex made under military contract, the plastic cased 1982 Mil-W-46374B. The plastic Timex camper of the same era is the same as the military version except it is signed Timex on the dial, and lacked the tritium and radiation markings. Campers are frequently incorrectly represented as a military issue as well as being from the Vietnam era. Although it seemed like that terrible war went on forever, it was over 10 years before the Timex versions were produced.
