The Spaceman was unlike anything seen before and Catena introduced the fleet at the Basel Fair of 1972. The large oval case appeared to be docked on your wrist held by a triple-forked Corfam strap by DuPont. The case also had a coned dome crystal half concealed by a coloured metal visor that allowed viewing of the dial to only the wearer. All hands and markers were perfectly seventies orange with models in a variety of colours only possible during that special decade.
The watches were powered by automatic and manual winding mechanical ETA movements and were distributed by a variety brands, among them Jules Jurgensen, Fortis, Tressa and Zeno, Omax
The success led to the development of new Spaceman a few years later, an audacious design by Le Marquand and appropriately named, the "Audacieuse".
