Adventure watch buyers face endless compromises. Luxury materials or smart connectivity. Professional diving capability or comprehensive health monitoring. Rugged durability or premium aesthetics. Huawei claims the Watch Ultimate 2 eliminates these trade-offs through three engineering pillars: industry-first sonar underwater communication, professional-grade 150-meter diving certification, and X-TAP dual-sensor health monitoring. Built with zirconium liquid metal construction rated 8.7 times more corrosion-resistant than previous materials, the Ultimate 2 targets users demanding both luxury craftsmanship and professional capability according to Huawei.

Positioning the Ultimate 2
Huawei positions the Ultimate 2 as their flagship adventure watch targeting serious outdoor enthusiasts who refuse to compromise. The watch sits above Huawei’s Watch series for tech users, GT series for fitness enthusiasts, Fit series for fashion consumers, and D series for health monitoring.
Huawei targets direct competition with Apple’s Watch Ultra while claiming superior diving specifications and unique sonar capabilities no competitor provides. The Ultimate 2 creates what Huawei calls a new category between luxury diving watches lacking smart features and consumer smartwatches compromising professional capability.
Compared to established dive computer brands like Suunto and Garmin’s Descent series, Huawei claims equivalent diving functionality with comprehensive smartwatch integration. Ocean Blue models at €999 and Compass Black versions at €899 position against luxury adventure watches costing significantly more.
Pillar Innovation 1: Industry-First Sonar Underwater 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. Advanced signal amplification and filtering enable stable watch-to-watch communication across varying conditions according to Huawei.
The system pairs with up to 50 dive buddies simultaneously, creating underwater networks designed to increase rescue chances during emergencies. Messages transmit in 500 nanoseconds enabling real-time communication that Huawei claims surpasses traditional underwater methods.
Consider a diver trapped in low visibility conditions 40 meters down. Hand signals require direct sight lines that murky water eliminates. Flashlights work only at close range with limited battery life. Huawei’s sonar system uses natural marine animal communication technology, providing reliable messaging regardless of water clarity or environmental obstacles according to the company.
Pillar Innovation 2: Professional Diving Engineering
The Ultimate 2 achieves 20 ATM water resistance equivalent to 200 meters depth with diving functions certified operational to 150 meters. The certification meets ISO 22810:2010 water resistance standards and EN 13319 diving accessory requirements according to Huawei.
An innovative mechanical sealing system automatically engages at 30 meters depth by sensing water pressure. The system creates what Huawei describes as an impenetrable barrier under extreme conditions. Multi-layer water-resistant film maintains audio quality while preventing infiltration.
Four diving modes support recreational scuba, technical scuba, free diving, and gauge instrumentation applications. Huawei positions this as diving equipment integrated with smartwatch capabilities rather than water resistance with diving marketing.
Pillar Innovation 3: X-TAP Dual-Sensor Health Monitoring
X-TAP health monitoring extends beyond wrist-based measurements through sensor integration first introduced on the Watch 5 in May 2025. The system incorporates a finger sensor on the watch’s right side requiring index finger placement for enhanced accuracy according to Huawei.
Full ECG sensor integration provides medical-grade insights users can share with healthcare providers. Huawei’s TruSense platform analyzes data from multiple sensor points simultaneously through advanced algorithms. The dual-sensor approach maintains accuracy during intense physical activity when wrist-only sensors fail according to Huawei.
Advanced cardiovascular monitoring includes heart rate tracking, arterial stiffness measurement, and sleep analysis designed for serious athletes. Sleep tracking, stress monitoring, and emotional wellness features provide health oversight beyond basic fitness tracking.
Premium Materials and Construction
Huawei engineered the Ultimate 2 using materials typically found in luxury timepieces costing significantly more. The zirconium-based liquid metal body provides 8.7 times more corrosion resistance than previous materials while delivering stronger construction for extreme outdoor conditions.
Ultra-hard coating systems achieve 300 percent better wear resistance. Sapphire crystal glass rates 9 on the hardness scale, second only to diamond. Nanocrystal ceramic bezel and rear components provide hypoallergenic properties while maintaining premium finish quality.
The 1.5-inch LTPO AMOLED display delivers 3500 nits peak brightness designed for underwater readability according to Huawei.
Design Variants and Configurations
The Ocean Blue model showcases diving watch heritage through blue and white 3-to-1 ratio bezel patterns drawing inspiration from classic underwater timepieces. Blue and white woven fluoroelastomer straps feature 3D wave textured finish with dual-color injection molding.
Extended diving straps and premium titanium options serve diving, adventure, business, and luxury applications. The Compass Black model targets adventure enthusiasts through black ceramic case construction with red highlights. Black fluoroelastomer straps provide sweat-resistant properties with extended options for wetsuit compatibility.
Sports and Outdoor Capabilities That Matter
Golf integration addresses the precision demands serious golfers face on challenging courses. Over 15,000 worldwide course maps provide hole layouts, hazard locations, and distance measurements. Dual-frequency positioning provides accuracy Huawei claims surpasses dedicated golf GPS devices.
Picture a golfer checking slope-adjusted distances mid-swing on a challenging course. Heat maps adjust recommendations for terrain slopes, providing insights that transform course management from guesswork to data-driven strategy according to Huawei.
Outdoor capabilities target adventurers venturing beyond cellular coverage. Satellite positioning provides remote area tracking. Fall detection offers automatic alerts during solo expeditions. High altitude monitoring supports mountaineering adventures where atmospheric conditions affect both device performance and user physiology.
Battery Performance That Enables Adventure
Battery performance directly impacts expedition planning and safety margins. Huawei claims 14 days standard operation or 8 days intensive usage through advanced power management. Wireless charging achieves 50 percent capacity in 30 minutes for expedition-ready quick charging.
Multi-week battery life means extended expeditions without charging anxiety. Cross-platform compatibility supports iOS, Android, and HarmonyOS with full smartphone integration regardless of platform. Health app connectivity enables data synchronization, health analysis, and dive log integration for session analysis and sharing.
The HarmonyOS interface distinguishes the watch from simpler fitness trackers through robust feature sets designed for applications requiring both luxury aesthetics and capability.
We’ll reserve judgment on Huawei’s sonar communication, diving depth, and health monitoring claims until comprehensive real-world testing validates performance against established competitors like Apple’s Watch Ultra and dive computers from Suunto and Garmin.
