The Huawei Watch Ultimate 2 smartwatch is the successor to the brand's first-generation Watch Ultimate that incorporates a number of key upgrades to give it an ultra-advanced functionality.
The smartwatch puts a 1.5-inch LTPO2 AMOLED display in the spotlight that's rated to deliver 3,500 nits of peak brightness, while also having display bezels that are 18% thinner than the previous model. The smartwatch is also paired with underwater sonar-based communication to let users send out a variety of communications to others in a 30-meter radius when diving. The device also has an SOS feature that will elevate the radius to 60-meters.
The Huawei Watch Ultimate 2 smartwatch is rated to support diving with a 150-meter rating to make it great for land and sea alike.
