World War Two Czech Pilot watch

This watches, known as Majetek, were used by mainly by the Czech Air Force during the late 1930s through the 1940s. The Majatek was produced by three different companies namely Longines, Lemania, and Eterna. While there are some small differences to each brand's design (for example, Longines' Majetek featured a coin-edge bezel and Cathedral hands and comes in metal dial or porcelain dial), the hallmark of the watch was its unique steel case with square bezel, round dial aperture and sloping straight lugs. Over the years, the Majetek was seen in two distinct layouts; one with a central sweeping seconds hand (Bottom picture Left watch) and one with a subsidiary running seconds hand at 6 o'clock position (Bottom picture Right watch)

With center sweeping seconds, it's very likely that this particular model was a later production watch, probably dating to the early 1940s. I have only managed to find the Longines and Lemania and once I have the Eterna, the three could be united as a family.

There is an embossed Crossed swords hallmark on the left hand top lug. Normally, this hallmark is found in Eterna watch but this Lemania happened to have the hallmark too. The crossed swords hallmark was widely used by the Czech military.
