my bad.. they are just jlc compressor wannabe with rotating inner bezel... Quote: "the compressor case was a patented case design by Ervin Piquerez, a swiss casemaker (EPSA) who sold his cases to a number of different brands. The compressor case had a unique seal construction which ensured water resistance through pressure on the gaskets; the crowns on compressor cases were not of the screw-down type. "
Sorry for any confusion
