Misc:

“Super-Compressor” refers to a patented case sealing method developed by watch case manufacturer Ervin Piquerez S.A. (EPSA). The design takes advantage of the water pressure the case is exposed to at depth to press the case back against the o-ring seal . More depth equals more water pressure equals greater seal. Dual crown Super-Compressor watches typically have a depth rating of 600 ft. This same concept was employed by Omega in the Naiad crowns used on Seamaster 300 watches in the ‘60s. Super–Compressor refers to the method of case sealing and nothing else. Dual crown styles are the most commonly seen, but there are single crown cases that have the Super-Compressor designation.

Mine says hi!

A wonderful watch! I am in love with the compressor/supercompressor technology that was used by many watch companies. I have two others, a JLC Polaris and a Lip Ski-Nautic. Claus
