The UC1 is part of Unimatic's Classic Series, which features an easy-to-read dial in matte black with Super-LumiNova C3 in light green for the best possible performance in all conditions. The permanent series is a functional evolution of the Unimatic references and is considered the archetype of the ideal performance timepiece. It is distinguished by the new CLASSIC lettering on the dial as well as on the screw-down case back, engraved with the 'Rosa dei Venti' diagram.
