With the HUAWEI WATCH Ultimate 2, the manufacturer is pushing the boundaries of wearable technology to a new level. As the world’s first smartwatch with sonar-based underwater communication, it sets new standards for safety, connectivity and a sense of adventure – ideal for athletes, outdoor enthusiasts and deep-sea divers alike.
- First smartwatch with sonar communication down to a depth of 150 meters
- Gap antenna system and Sunflower Positioning for maximum precision
- Robust zirconium housing, TruSense™ health system and up to 11 days of battery life
- Available from 899 euros with launch bonus and free FreeBuds Pro 4
Communication at depth – a quantum leap for diving technology
The HUAWEI WATCH Ultimate 2 is more than a wearable – it is a lifeline for underwater adventures. Its sonar-based communication function makes it possible for the first time to send messages and emojis to other watches within a radius of up to 30 meters, even at a depth of 150 meters. This not only makes diving safer, but also more coordinated – for example during group or exploratory dives. The watch also offers an underwater SOS signal that can be received up to 60 meters away to quickly call for assistance in an emergency.
The housing is made of a zirconium-based metal alloy and can withstand even the highest pressure loads. It is combined with a two-tone nanoceramic bezel and scratch-resistant sapphire crystal, ensuring robustness and elegance in equal measure. This technical basis makes the HUAWEI WATCH Ultimate 2 not only a companion for extreme sports, but also a stylish smartwatch for everyday use.
Precision, tracking and endurance for every adventure
In addition to its groundbreaking diving communication, the watch impresses with its smart connection technology. The Gap antenna system ensures stable signal transmission and strong connectivity – whether in the water, in the mountains or in urban areas. The Sunflower Positioning System combines dual-band signals with five satellite networks and intelligent route optimization to ensure accurate positioning data even when coverage is difficult.
Thanks to the integrated eSIM, the smartwatch can make calls independently of the smartphone, while AI-supported noise suppression ensures clear voice quality. With its combination of fall detection, emergency SOS and altitude monitoring, the Ultimate 2 is aimed specifically at adventurers who want to rely on their technology.
In everyday life, it scores with the TruSense health system, which uses highly sensitive rear modules and X-TAP technology to record key body metrics. From continuous heart rate measurement and SpO₂ monitoring to sleep analysis, the watch delivers precise health data in real time. Despite all these functions, it boasts up to 11 days of battery life in energy-saving mode and 4.5 days in standard mode.
Design meets performance – for land, water and everyday life
The HUAWEI WATCH Ultimate 2 is available in black or blue and combines technical complexity with a sporty, elegant design. HD golf course maps, outdoor training modes and professional sports analysis extend the range of functions beyond diving. The watch is therefore aimed at anyone who wants to test their performance under extreme conditions or seamlessly combine everyday life and adventure.
The interplay of function, safety and style shows how HUAWEI is redefining the boundaries of digital wearables: from navigation on the mountain to tracking while diving to health management in everyday office life. Every component of the Ultimate 2 is designed to be precise, durable and intuitive.
Conclusion
The HUAWEI WATCH Ultimate 2 opens up a new era of connected wearables with its sonar-supported diving communication. It combines sophisticated technology with a robust design and precise health tracking – a real premium tool for explorers.
From October 9, 2025, the smartwatch will be available in black and blue from 899 euros (RRP) in the HUAWEI online store, the flagship store in Berlin and at selected retailers.
