The Rolex Datejust "Thunderbird" (Ref. 1625) is a historic hybrid of a dress watch and a tool watch, most famous for being the first Rolex to feature a rotating timing bezel. While it shares the "Datejust" name, its association with the U.S. Air Force's Thunderbird aerobatic team earned it its iconic nickname.
