A sport-leaning expression of the Datejust, the reference 116261 Turn-O-Graph Thunderbird brings the line's familiar date format into a more purposeful steel and rose gold execution. This watch tempers that two-tone case with a silver dial, giving the design a restrained, technical cast rather than overt formality. Its automatic movement and date complication keep the emphasis on practical daily use. At 36mm wide and 12mm thick, it wears with the compact, balanced proportions collectors expect from a classic Datejust.
