1966 Elge Chamonix.

I love the case shape, it reminds me the 50s Eternas issued to the Czech Air Force.

Elge watches were produced by the French manufacturer Ets Yolabased in the large town of Annecy in the Haut-Savoie just over the Swiss border from Geneva. They were in business from the mid 1940s until the early 1970s, during this period they build a solid market in China.
