In our market there is no problem to buy a lot of old Prim Sport I, but if it is in good condition the price is very high and you should be very carefull of parts from Parexo and parts from others type of Prim. It is good business for some people and mainly on Aukro.cz is a lot of "fakes". Watches from my father were in very bad conditions, bad body, bezel, hands and dial also. So I bought parts for renovation and now I have great watches which I can give to my son. With "heart" from my father. It was only one way how to wear. The price of renovation was: Parts: 8.000,- CZK (cca 1.330,- PLN) - now the parts are more expensive, i think +20% Service: 1.300,- CZK (cca 220,- PLN) I have black date circle also, but I don't have time to change for the white. After renovation with black date (photo of my colleague, there is inverted bezel also): For more photos after renovation (versions with/without date, inverted bezel, other colors of dials, hands etc.): http://forum.chronomag.cz/index.php?/topic/11060-renovované-igeny
