The Rolex Datejust Turn-O-Graph reference 1625 in 18k yellow gold and stainless steel with a black dial—famously known as the "Thunderbird"—is a highly collectible vintage watch that bridges the gap between classic dress style and a tool watch.

  The Turn-O-Graph model earned the nickname "Thunderbird" in the 1950s when it was officially adopted by the US Air Force's elite Thunderbird stunt squadron. Reference 1625 was produced roughly from the late 1950s through the late 1970s. Finding a two-tone version paired with an original black or black gilt dial is relatively rare, as champagne and silver dials were far more common during this era.
