A beautiful IWC with a silver sunray dial with black stone and steel hour markers, a date display at three o’clock and the IWC logo at 12 o’clock in typical 1970s applique. Inside the very beautiful IWC 8541B movement with its decorations and its lot innovations, more efficient thanks to the famous Pellaton winding apparatus, simpler thanks to its mechanism which allows it to be serviced like a manual mechanical watch by dissociating the automatic mechanism.
