This timepiece features a symmetrical brushed and polished case with an integrated bracelet offering easy comfort adjustment. The beige dial with black gradient showcases vintage Super-LumiNova numerals and markers, maintaining the original's legibility, while adding a Small Seconds display at 6 o'clock with a beige varnished hand.
