On November 13, 2025, Huawei Consumer Business Group announced that its latest exceptional exploration watch, the WATCH Ultimate 2, boasts an impressive 150-meter diving-grade waterproof capability. This remarkable timepiece incorporates a newly patented technology termed 'a sealing assembly, housing assembly, and electronic device'. This innovation operates by detecting variations in water pressure. Subsequently, it activates a pressure differential cylinder, which then moves the first sealing gasket to create a watertight seal. Furthermore, the watch has secured dual certifications: one for water resistance in line with ISO 22810 standards, and another for its diving proficiency, adhering to ISO6425 and EN13319 regulations.
