I have these old Prim watches. The one up on the right is never worn up and it is from the 1983. The one down in the middle needs crystal and service and a second hand. I like that dial very much. I would like to see your Prim watches if anyone has.
Apparently PRIM was a trademark of Chronotechna from Nové Mêsto in the Czech Republic, created around 1956.
Still active, company is called ELTON, sitting still in Czech republic, Nové Město nad Metují. Part of their business is restoration now. They restore old PRIM watches that youngsters find and want to keep for next generation. They also created a special edition for Czech Olympic Team. I remember the engraving. Very true, very Czecho-slovak. "Nemuzes, pridej!" - "If you are tired, just accelerate!" - Emil Zatopek, Czechoslovaklong-distance runner best known for winning three gold medals at the 1952 Summer Olympics in Helsinki. He won gold in the 5,000 metres and 10,000 metres runs, but his final medal came when he decided at the last minute to compete in the first marathon of his life. He was nicknamed the "Czech Locomotive".
well, simply put, that is the result of crazy 90s in CZ/SK. MPM claims brand ownership I think, but it belongs to ELTON (Elton employee designed PRIM logo back in 1969). There should be information online. If interested, here is some reading on that brand ownership fight.
