Up for sale is a vintage Air King ref. 5500. Its serial dates the watch to 1979 (serial begins with 57). The patina of the lume between the hands and dial are consistent. The acrylic crystal is in great condition with no deep knicks or scratches. Watch is currently running +1-4 seconds a day, depending on its position, but YMMV. The bracelet has been refinished by Rolliworks in May of 2022. PDF receipt is attached in one of last pics of imgur link. Watch does not come with box and papers. It has enough links to fit wrists up to 7.2 inches.
