Rolex Oyster Perpetual Date 15505

The Rolex Oyster Perpetual Date ref. 15505 is a two-tone model produced during the late 1970s through the 1980s. It features a 34mm case combining stainless steel with an 18k yellow gold fluted bezel, offering a blend of durability and understated luxury. The watch comes equipped with an acrylic crystal and the Cyclops magnifier above the date window at 3 o’clock. It uses a screw-down crown and caseback to maintain water resistance, in line with Rolex’s Oyster case standards. Powering the 15505 is the Rolex Caliber 3035, a COSC-certified automatic movement with a quickset date function and a 48-hour power reserve, widely respected for its reliability and precision. Dials are commonly found in champagne, silver, and white variants, usually featuring gold-tone baton markers and matching stick hands. The lug-to-lug measurement is 41mm, and the lug width is 19mm, providing a well-balanced wrist presence. The 15505 is favored by collectors who appreciate vintage Rolex models with bi-metal construction, a classic fluted bezel, and a robust movement in a more compact size.
