The Rolex Oyster Perpetual has constantly been the front-runner in a collection of legendary watches, it is the most recognized and most easily well-known of watches. Artistically, these models have evolved finely over the years, but their u***takable individuality has always been respected. Over time it has become a standard. The Oyster benefits from all the technology and expertise of Rolex. In a time when the pocket watch was the order of the day, Hans Wilsdorf, the founder of Rolex entered the world of Swiss watch *** in the early 20th century. He started to envision a watch being worn on the wrist. At that time, wristwatches were not very precise but he foresaw that they could become reliable aside from being elegant. He equipped them with tiny, very accurate movements made by a Swiss watch *** company in Bienne to persuade the public of the dependability of his determinedly innovative timepieces. Mercedes Gleitze, a young English swimmer, crossed the English Channel wearing the Oyster only a year after its creation in 1927. Proclaiming the success of the waterproof watch, Hans Wilsdorf published an advertisement on the front page of the Daily Mail to celebrate a milestone event in which Gleitze, at the end of her swim, which lasted over ten hours, found out that the watch remained in perfect working condition. In 1931, the Oyster soon possessed yet another outstanding feature. A clever system at the basis of every modern automatic watch, Rolex created and patented the world's first self-winding mechanism with a perpetual rotor. To receive certification from COSC (Controle Officiel Suisse des Chronometres), which is an independent not-for-profit organization; a watch must demonstrate extreme precision in a variety of positions and temperatures. SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED, the four *** words engraved on the timepiece's dial, mean that the movement of this watch has endured fifteen days and nights of testing by the COSC; thus, the impeccable standard level of quality for every Rolex chronometer. The back of any Oyster, which is sealed to the case with an immense torque of 5 Newton Metres, produces an environment that protects the movement from water, pressure, shocks, dust and any other intrusive element. Nowadays, a Rolex watch enjoys autonomy of approximately 50 hours. The Perpetual rotor system of the Oyster movements is identifiable by two red reversing wheels that allow the rewinding of the movement in spite of the rotation direction of the swinging weight. The self-winding device transmits continuous natural energy to the watch. It consists of a half-moon shaped oscillating weight, which spins freely on its central axle, in one direction, then the other with the normal movements of the wrist. The oscillations of the weight generate energy which is accumulated in the mainspring. The 904l steel is what Rolex uses for its steel watch cases; its steel usually set aside for the chemical industry. It is made of a super alloy unimaginably resistant and able to be polished to a higher degree, where maximum resistance against corrosion prove vital. In this fashion, 904l perfectly goes together the other valuable metals used by Rolex. One little imperfection of the Oyster was that the winder had to be unscrewed to wind the watch. If the owner forgot to screw it back in firmly, or as the threads or waterproof seals wore out over time, the watch was no longer completely waterproof. This was worked out by Rolex in 1931, with the introduction of the perpetual self-winding movement. A self-winding watch has an internal rotor �C a semi-circular metal plate which turns around back and forth with any movement of the wrist, rewinding the mainspring that powers the watch. Now, the external winding knob (the crown) was required only for occasional time corrections and the watch's waterproofing system became more dependable. Remaining privately owned, Rolex may well take the long term vision of the future without worrying about shareholders and the next quarter's earnings. Importance in high-quality Swiss-made movements duly made a comeback in the 1990s, and fine watch *** was reborn to a stronger industry. The Rolex Company produces some 650,000 watches per year and keeping firm control over distribution, sales outlets, and price.
