Rolex Oyster Perpetual Date 1550 Description

The Rolex Oyster Perpetual Date ref. 1550 is a vintage midsize reference from the 1960s and 1970s, part of the classic Date series that emphasized understated elegance and daily wear reliability. Housed in a 34mm Oyster case typically made from stainless steel or two-tone steel and gold (Rolesor), the 1550 features a smooth or fluted bezel and a domed acrylic crystal with the signature Cyclops lens. It retains the standard Rolex screw-down crown and caseback, ensuring water resistance consistent with the brand’s standards. Powering the 1550 is the Rolex Caliber 1570, a well-regarded automatic chronometer movement offering high reliability, a 48-hour power reserve, and hacking seconds for precise time-setting. Dials were commonly silver, black, champagne, or occasionally blue, with applied indices and stick or alpha hands depending on the year of production. The lug-to-lug measurement is approximately 41mm with a lug width of 19mm, offering compact and balanced wrist proportions. This reference is valued by vintage collectors for its durability, timeless design, and connection to Rolex’s mid-century production period, often serving as an excellent entry point into the brand’s classic catalog.
