Quite rare civilian used 1940’s Eterna Majetek (Czech Air Force) . A military watch from Eterna, which has developed innovative movements and has continued to make its name in the history of watches. An excellent individual that still beautifully maintains a well-balanced Arabic index and a mirror dial that reflects strings. The screwback waterproof case has a solid edge.Cal 852S manual 38 mm big size . Good condition. Watch only. Original Czech Air Force in WWII not re-edition ! most civilian use didn’t get the sword on the top left corner n that’s why this one is rare .
