Hi!
That was actually my first reply on Watch Crunch. I will make some posts regarding Prim watches. Thanks! 

I live in Prague (Czech Republic) and Prim watches have fascinated me since I was a kid.
Two companies are allowed to sell watches with the traditional Prim label in the Czech Republic. Elton Watchmakers, which has been producing watches for over sixty years, and MPM-Quality, which obtained a trademark for the brand in 2001. The Supreme Court rejected an appeal by Elton, which wanted the courts to ban its competitors from using the mark.
The Elton watch company is a continuation of the manufacture of watches that dates back to 1949 in Nové Město nad Metuji. Its Prim designation was taken over by the company from its legal predecessors. It also uses the European trademark Manufacture PRIM 1949.
 

Hello, everyone! 
I live in Prague (Czech Republic) and Prim watches have fascinated me since I was a kid. I inherited my favourite Prim Sport II from my grandfather. It's not a dazzling quality watch, but I will always like this brand the most, the nostalgia is strong. Unfortunately, I only have experience with the old models. Most are from the 1970s.

Prim's are very cheap in the Czech Republic and some of their designs are just great. Some models are not cheap at all. Probably the most expensive Czech watches come from the workshop of Mohelnice watchmaker and goldsmith Luděk Seryn and bear the name Imperator (first picture), inspired by victory and ancient Rome. It glitters with gold and diamonds. Their value is CZK 1.9 million. (85,700$) 
Also interesting is the PRIM Skeleton watch (second picture) sold for 1.2 million crowns. (54,000$)
