Huawei Watch Ultimate 2 launched with 150m diving and sonar communication

September 20, 2025

As you might have noticed, Huawei launched the premium Watch gt 6 series (alongside the pro) but many may not know that they also launched an additional smartwatch, yes, and that watch is the Huawei Watch Ultimate 2, which is also an upgrade to its predecessor, the regular Watch Ultimate. This new premium smartwatch features sonar-based underwater communication (which may indeed also sound like something out of a spy movie), and its target is divers and adventure people who need gear that can handle extreme conditions. Now, let’s jump in this article, where I will discuss everything about the latest Huawei Watch Ultimate 2, including its price in Nepal, specifications, and availability.

Huawei Watch Ultimate 2 Overview

Design and Display

The Ultimate 2 is basically Huawei’s answer to Garmin’s Descent series and other professional dive computers, but with smartwatch features thrown in. It’s a direct upgrade over last year’s original Watch Ultimate, pushing the diving depth from 100 meters to 150 meters and by adding that wild sonar communication feature. And this isn’t really competing with the GT 6 series at all. We’re talking about a completely different price bracket and target audience.

Starting off the design, the Ultimate 2 uses “zirconium-based liquid metal” for the case, which is supposedly more durable than regular titanium or stainless steel. The Ocean Blue model gets a steel version of this liquid metal, while the Compass Black uses pure zirconium-based construction. Both variants feature dual-tone nanocrystal ceramic bezels and sapphire glass. The watch is chunky at 80.5 grams without the strap, hence this makes it substantially heavier than the recently launched GT 6 Pro.

The 1.5-inch LTPO AMOLED display pushes 3,500 nits peak brightness, which is even brighter than the GT 6 Pro’s impressive 3,000 nits. Display bezels are 18% thinner than the original Ultimate.

Sonar Communication

Huawei integrated the first compact sonar system into smartwatch architecture. The miniaturized sonar module operates at 3-5 kHz frequency optimized for underwater clarity and long-distance performance. You can send preset messages and emojis to other Ultimate 2 watches within a 30-meter radius underwater. For emergencies, there’s an SOS feature that can reach devices up to 60 meters away if another diver forwards the message.

The system can pair with up to 50 dive buddies simultaneously by creating underwater networks. But I’m a bit skeptical about how well this works in real-world conditions. Underwater acoustics are tricky, and things like boat engines, underwater construction, or even large sea creatures can mess with the signals.

Professional Diving Features

Anyway, as mentioned above, the Ultimate 2 supports diving up to 150 meters, which puts it ahead of most smartwatches in this category. It uses the Bühlmann ZHL-16C decompression algorithm, which is the same standard used in professional dive computers.

You get all the typical dive computer features: depth tracking, decompression limits, ascent rate warnings, and gas mixture calculations. The watch can handle recreational diving, technical diving, scuba diving, and free diving with different settings for each. Compared to established dive computer brands like Suunto and Garmin’s Descent series, Huawei claims equivalent diving functionality with comprehensive smartwatch integration. But Garmin’s been in this game longer and has more proven track records with serious divers.

Expedition and Adventure Features

Beyond diving, the Ultimate 2 packs expedition features for mountaineering and outdoor adventures. The upgraded antenna system supposedly delivers better connectivity in extreme conditions. There’s route import functionality, offline map downloads, and the usual GPS tracking with dual-frequency positioning across five satellite systems. High-altitude adaptation alerts help prevent altitude sickness, and fall detection can send SOS calls if you take a tumble. The golf mode includes 17,000+ course maps worldwide with detailed green layouts and ball trajectory tracking.

Battery Life

The Ultimate 2 manages 4.5 days of typical use when paired with Android, or 3.5 days with iOS. With always-on display enabled, you’re looking at 3 days (Android) or 2.5 days (iOS). For specific activities, you get 18 hours in dive mode (12 hours with sonar communication enabled), 40 hours in expedition mode, and 24 hours for golf.
