Rolex Oyster Perpetual 3595 Description
The Rolex Oyster Perpetual ref. 3595 is a vintage reference produced in the late 1930s, during a pivotal period in the evolution of Rolex’s waterproof self-winding wristwatches. This model features a 30mm case made of stainless steel or gold, incorporating Rolex’s renowned Oyster case architecture—complete with a screw-down crown and caseback, along with a domed acrylic crystal for added protection against moisture and dust. It was equipped with one of Rolex’s early automatic movements, likely a bumper or early rotor system, delivering a power reserve of approximately 36 hours and signaling the advancement of the brand’s Perpetual winding technology. The dial design adhered to the functional aesthetics of the era, usually with a small seconds sub-dial at 6 o’clock, luminous radium-treated hands and indices, and minimalist hour markers set on a silver or cream-colored background. The lug-to-lug measurement was approximately 36mm, with a lug width of 16mm, providing a compact and wearable case profile typical of its time. Though the 3595 did not gain widespread recognition, it played a critical role in the foundational years of Rolex’s Perpetual development and waterproofing standards. As such, it is a notable piece for collectors interested in Rolex’s early innovations and historically significant yet lesser-known references.
