On the original vintage Swiss Tropic Sport strap . See this article for more info ! And see for yourself why Piquerez SA EPSA cased Super Compressor Dive watches are THE shit . e term Super Compressor is one that is quite often misused these days . Most people associate Super Compressor SC with any watch that has dual crowns and an internal rotating bezel , but it ' s not that simple . Super Compressor is a trademarked name for specific case designs made by the case manufacturer Ervin Piquerez S . A . EPSA . They designed a patented case sealing method that actually became more water tight the deeper the watch went . The deeper you went , the more pressure was applied to the caseback , pressing it against the Oring gasket . epsaadMost of the SC casebacks have a spring on them , so that the back was tight without being completely compressed against the case . With increasing water pressure , the back was pressed further against the case increasing water resistance . Another advantage of this configuration is that the Oring did not have full pressure on it constantly , extending its life . Most SC watches were rated to a depth of 600 ft . ad . jpgsupercompressorsThe watch display an amazing array of vibrant colours going from the sparly orange to the deep oxblood colour of the bezel .
