The Rolex Datejust Turn‑O‑Graph reference 1625 is a distinguished vintage icon, often affectionately called the “Thunderbird” by collectors. Introduced in the 1960s, this iteration features a 36 mm solid 18 K yellow gold case paired with a matching engine‑turned rotating bezel and integrated jubilee bracelet, delivering both elegance and functional flair. Powered by Rolex’s robust automatic caliber—initially the 1565 and later the 1575—this watch offers a refined sweep seconds, date display, and approximately 48 hours of power reserve, underscoring Rolex’s commitment to precision. The warm champagne dial with gold baton indices and hands enhances the monochromatic allure, while its rotating bezel speaks to the model’s tool‑watch heritage and aviation lineage. Though not a limited edition, its production run was relatively brief, and the Turn‑O‑Graph’s association with the U.S. Air Force Thunderbirds adds a layer of historical cachet. Collectors prize the 1625 for its seamless blend of utility and luxury, its quality movement, and the rarity of full‑gold examples. This reference stands as a testament to Rolex’s mid‑century innovation and remains a compelling choice for seasoned enthusiasts seeking a vintage Datejust with character and provenance. Excellent Condition with EWC travel pouch.
