On November 14, 2025, Yu Chengdong announced that the Huawei WATCH Ultimate 2 is equipped with a miniature sonar device, launching the industry's first dolphin sonar communication function. This makes it the first underwater communication watch in the industry that does not require external accessories, with a maximum communication distance of 30 meters. It supports communication among 50 dive buddies, covering recreational diving and underwater work scenarios. This technological breakthrough overcomes the limitations of electromagnetic wave attenuation underwater, addressing the pain point of lost communication among divers by using sound wave transmission, thereby enhancing underwater collaboration efficiency and safety.
