This reference is defined by its 40mm maxi-case which featured thicker lugs and crown guards than its five-digit predecessors—paired with an exceptionally scratch-resistant black Cerachrom bezel insert. Its powered by the Caliber 3135, a robust, COSC-certified automatic movement known for its bi-directional winding and Rolex's proprietary Parachrom hairspring.
Founded in 1905 by the visionary Hans Wilsdorf, Rolex was born from a singular, revolutionary idea: to transform the wristwatch from a fragile piece of jewelry into a robust, precise, and reliable daily companion. This ambition was masterfully realized in 1926 with the invention of the Oyster, the world's first waterproof and dustproof wristwatch case. Proven by a triumphant swim across the English Channel on the wrist of Mercedes Gleitze, the Oyster case established the foundational pillar of the brand's identity—performance and dependability in the most demanding conditions—a standard to which every Rolex is held to this day.
Building upon this foundation, Rolex went on to pioneer the defining features of the modern watch, including the self-winding Perpetual rotor in 1931 and the date-displaying Datejust in 1945. The brand then cemented its legend by creating the "professional tool watch" category, developing iconic models engineered for specific endeavors: the Submariner for deep-sea diving, the GMT-Master for intercontinental pilots, and the Cosmograph Daytona for the world of motorsports.
Today, Rolex positions itself as the universal symbol for success, quality, and prestige. As a fully integrated manufacturer, the brand exercises complete control over every component, from smelting its own proprietary gold alloys to assembling its "Superlative Chronometer" certified movements with uncompromising precision.
