1908 At 8: 00 a.m. on July 2, the Rolex trademark was officially registered. The first batch of Rolex watches received immediate attention because of their superb technical quality. A small Rolex watch was awarded the A-class certificate by the Royal Botanical Garden Observatory in 19 14, which is the highest evaluation never issued by this famous observatory in Britain. Its accuracy has been recognized, which is a world event, making the watch suddenly worth double in Europe and America. From then on, the quality of Rolex represents precision.

After the First World War, Rolex moved back to Geneva. Driven by its founder, Rolex kept innovating, creating and perfecting itself. It has two research directions: waterproof and automation. 1926, the first waterproof and dustproof watch finally came out, which is the famous "oyster" watch. 1929 the economic crisis hit Switzerland hard, but Rolex was not affected. During this period, it invented the automatic winding device and created the "permanent" watch that was all the rage later. This automatic watch has a pendulum that has never been used on a watch before. It has brought a revolution to the watch industry and is the pioneer of all automatic watches. 1945, Rolex also produced watches with dates and watches that can display dates and weeks in 26 languages.
