Background of Birth: In the 1940s and 1950s, people were enthusiastic about developing seabed resources. The exploitation of oil, natural gas, etc. prompted Rolex to develop watches suitable for diving. In 1953, the first Rolex Submariner came out. At that time, a director of Rolex proposed to create a diving watch due to his love for diving. It had good seabed recognition, a high-contrast black face and large luminous hands, as well as good anti-magnetic, waterproof, anti-collision structures, and corrosion resistance and resistance to severe temperature differences. Once launched, it was very popular.
