Ralf Tech has switched from the production of professional diving equipment to the watchmaking sector since 2008. Among the models in the catalogue, the WRV in the '1977' version pays homage to the 1970s with its vintage aura but with the technical features of a professional diver, with a unidirectional rotating bezel, screw-down back and water resistance of 20 atmospheres. It complies with the ISO 6425 standard.
