It is characterized by a 39mm symmetrical stainless steel case without crown guards, a matte black \"Base 1000\" metal bezel, and \"Broad Arrow\" handset. The watch is powered by the manual-wind Calibre 321 movement. Due to a short production window, surviving examples in original condition are rare.
