A beautiful IWC with a silver sunray dial with alternating Roman numerals and indexes in black stone and steel, a date display at 3 o’clock and the IWC logo at noon painted in black, typical of the 1960s. Inside, the very beautiful IWC 8541 movement with its decorations and its share of innovations, more efficient thanks to the famous Pellaton winding mechanism, simpler as it can be revised like a manual mechanical watch by dissociating the automatic mechanism.
