Hublot is a young watch brand that was the first to combine precious metals and natural rubber as raw materials. As a product of LVMH, a world-renowned luxury group, Hublot's design has a strong conceptual style and a modern sense. The diver's watch stands for the Oceanographic 4000 and has a 6.5mm thick crystal, which is much thicker than a normal glass – which reduces its portability but ensures a tight seal. Hublot's extensive use of SuperLuminovaTM coating combined with titanium emits a cool green glow to ensure visibility in the deep sea. At the same time, it is equipped with a helium exhaust valve, which has complete professional functions and is sold in a number of designs at different prices.
