Following the reference 6202, which is arguably the predecessor to the Submariner, the Turn-O-Graph references 6309 and 6609 were introduced and produced for a short period between 1954 and 1959. During this time, the Turn-O-Graph became associated with the U.S. Air Force’s Thunderbird aerobatic team, giving rise to the “Thunderbird” nickname.

The reference 1625 followed and remained in production until around 1977 — the present example dates to 1974. We love vintage Datejusts here at Falco, and these Turn-O-Graphs are easily some of the coolest of the bunch
