Rolex Oyster Perpetual 4134

The Rolex Oyster Perpetual ref. 4134 is a seldom-seen vintage model produced during the late 1930s, representing one of the early integrations of Rolex’s waterproof Oyster case with automatic movement technology. It features a compact 30mm case available in stainless steel or gold, incorporating the screw-down crown and caseback that define the Oyster series, along with a domed acrylic crystal for added protection. Inside, it likely carried one of Rolex’s early automatic movements—potentially bumper or rotor-based mechanisms—which delivered an estimated 36-hour power reserve. Dials were conservative in design, with a silver or cream base, small seconds at 6 o’clock, applied numerals or markers, and radium-lumed hands that adhered to the design codes of the late 1930s. The lug-to-lug distance measures approximately 36mm, while the lug width is 16mm, providing a comfortable vintage fit. The 4134 is historically important as part of the pioneering lineup that contributed to the rise of the Oyster Perpetual platform, setting the stage for the evolution of Rolex’s self-winding waterproof watches. Its rarity and transitional status make it an appealing acquisition for collectors interested in the brand’s early automatic innovations.
