Rolex Datejust Turn-O-Graph Thunderbird 1625/8

Reference 1625/8 is the solid gold version of the vintage Datejust ‘Turn-O-Graph’, produced from the early 1960s to the late 1970s. Its primary technical feature is a bi-directional rotating ‘Turn-O-Graph’ bezel. This bezel, crafted from solid 18k yellow gold (/8 suffix), features a 60-minute scale with raised, polished numerals against a finely textured, matte background. The watch is powered by the Rolex Caliber 1575, a non-quickset date movement. The 36mm case is fitted with an acrylic crystal. Its significance lies in its status as a luxurious reinterpretation of Rolex’s first rotating-bezel tool watch.
