The Huawei Watch Ultimate 2 is the first smartwatch to support underwater sonar communication

This groundbreaking smartwatch from Huawei is the first to integrate underwater sonar-based communication. This feature significantly enhances safety and convenience for deep-sea divers, allowing them to send pre-set messages and emoticons to other watches within a 30-meter range. Additionally, it boasts an underwater SOS feature with an effective range of 60 meters, a vital tool for emergency situations.

It is certified for 150-metre diving

Engineered with a zirconium-based liquid metal casing, the Huawei Watch Ultimate 2 is certified for 150 meters of diving. This exceptional waterproof rating positions it among the elite in diving smartwatches. The incorporation of an “innovative gap antenna system” not only boosts signal strength outdoors but also enhances navigation capabilities with the Sunflower Positioning System, which employs dual-band five-system positioning and advanced algorithms for precise navigation in challenging underwater conditions.

eSIM support is included, as is Fall Detection

One of the watch’s highlight features is its eSIM capability, allowing users to make calls directly from the device without needing a smartphone nearby. Safety features like Fall Detection, Emergency SOS, and High-altitude monitoring add to its versatile functionality. Coupled with health features like TruSense supported by X-TAP technology, users can track up to 11 key health metrics, including fingertip SpO2 measurements, heart rate, and sleep patterns.

It offers up to 11 days of battery life… if you’re saving up

The battery performance of the Huawei Watch Ultimate 2 is commendable, offering up to 11 days of use in battery saver mode. Under standard operating conditions, users can expect around 4.5 days of usage—an improvement over many competitors, though slightly less than Huawei’s own GT 6 and GT 6 Pro models.

The Huawei Watch Ultimate 2 is available for pre-order on the Huawei Store now, with pricing currently available for the UK market. The Compass Black variant is priced at £799.99, while the Ocean Blue model retails for £899.99. Huawei is also providing a range of launch offers, making this an appealing option for fitness enthusiasts and divers alike across Europe and various other markets.
