One of the most famous wristwatch manufacturers is the ELTON chech company founded in 1949. It's main wristwatch brand is PRIM, the equivalent of OMEGA for quality and design. Unfortunately, the eastern european products never got the chance to compete with the swiss counterparts due to the political division. People still have their PRIM watches in working condition after 40 years (my cousin still has one). In the socialist period, you would receive as reward (a good student or another good deed) a good mechanical watch manufactored by the same factory that made the famous PRIM, but under the name of Ruhla and Slava. Both are very durable watches, and many people still wear them. I think the Prague watches come either from the same factory, or from some newly formed company after the 90's with the knowledge and know-how from the same manufacturer. The watches look impresive, especially the skeleton automatic one. Maybe, you'll buy one for yourself. In any case, it would be nice if you posted some pictures of it if you decide to purchase it.
