Datejust Turn-O-Graph 6309

A rotating, engine-turned bezel gives ref. 6309 a more purposeful outline than an ordinary Datejust. Introduced in 1954, this early Turn-O-Graph is closely associated with the “Thunderbird” name; the date display and 36 mm Oyster case keep its timing bezel tied to familiar Datejust proportions.
