Our visionary Hans declared that the biggest problems of our time for watches were humidity and dust. In response to this problem, he decided to create a waterproof watch, and in 1926 the brand released the model that revolutionised the era: the Rolex Oyster (a reference to oysters being perfectly waterproof). First waterproof collection of the brand.
In order to promote the watch model, the brand will take advantage of Mercedes Gleitze's achievement to praise the fantastic capabilities of its product.
Indeed, the young woman was the first English woman to cross the Channel and she wore a Rolex Oyster around her neck, which, on her arrival, was still working perfectly and had not gone out of adjustment. The front cover of the Daily Mail newspaper featured the young woman with the following inscription: "Rolex Oyster defies the elements".The model is no longer available and will have left its mark on history.
However, the main remaining weakness was the fact that the watch mechanism had to be reassembled to ensure that it worked, as the multiple disassemblies of the crown resulted in the water resistance of the watch being damaged. As the dial became less water resistant, the watch lost its effectiveness.
In order to solve this problem and to finish imposing the brand in the watchmaking world, Hans Wilsdorf bought many patents allowing him to create the mechanism now used by many watch models: The Rotor Perpetual, this system is self-powered by the energy produced by the movements of the wrist which avoids having towind the mechanism every day, thus allowing the model of watch of Rolex to gain even more notoriety.
