Rolex was registered as a trademark by Hans Wilsdorf in 1908. Hans focused on producing high-quality, practical watches. In 1926, he obtained a patent for the world's first truly waterproof Oyster case, and in 1931, he developed the "perpetual mechanism," the forerunner of self-winding watches. Since then, the company has mass-produced models with timeless designs and outstanding practicality. It is a brand that has earned an overwhelming sense of trust, worthy of being called the "king of the watch industry."
