Independent connectivity: phone-free eSIM cellular calling with AI noise cancellation rated five stars
Precision navigation: dual-frequency five-system GNSS through the HUAWEI Sunflower Positioning System
Health monitoring: HUAWEI TruSense System with X-TAP technology delivering a 60-second Health Glance across up to 10 metrics
High-visibility display: 1.5-inch LTPO screen with 3,500-nit peak brightness for clear readability in sunlight
Durable construction: zirconium-based amorphous alloy case, nano-crystalline ceramic bezel, and sapphire glass

Diving & Underwater Communication
The watch is certified under EN 13319 for diving to a maximum functional depth of 150 metres and carries an ISO 22810:2010 water-resistance rating of 20 ATM. It passed a static pressure test at 200 metres for 10 minutes. Decompression calculations use the Bühlmann ZHL-16C algorithm.
Sonar-based underwater communication lets the watch send messages to a dive partner at ranges up to 30 metres. For SOS situations, the relayed SOS range extends to 60 metres. Battery life in dive mode reaches up to 18 hours, or up to 12 hours with sonar underwater communication active.

Connectivity & Navigation
Phone-free eSIM cellular calling allows the watch to place and receive calls without a paired smartphone. AI noise cancellation on calls holds a five-star rating for noise suppression. An all-new antenna system is optimised for eSIM calls and navigation.
Positioning is handled by dual-frequency five-system GNSS within the HUAWEI Sunflower Positioning System. Full-colour offline maps can be downloaded to the watch for navigation without a phone connection. The watch also provides a golf course database covering over 17,000 courses.

Health Monitoring
The HUAWEI TruSense System with X-TAP technology powers the watch's health-sensing capabilities. A Health Glance report completes in 60 seconds and captures up to 10 important health metrics. Real-time blood oxygen saturation is measured via X-TAP.
Sleep monitoring tracks heart rate, respiratory rate, blood oxygen saturation, and heart rate variability. Cardiac health features include ECG and pulse wave analyses with a warning for atrial fibrillation. The watch can also detect up to 12 emotional states.

Outdoor & Safety Features
An expedition mode delivers up to 40 hours of battery life and supports full-colour offline map downloads. Trail-run mode provides up to 22 hours and golf mode up to 24 hours of battery life. A high-altitude adaptation alert activates at elevations of 2,500 metres or higher, warning of signs of altitude sickness.
Fall detection triggers an automatic SOS call after 60 seconds without a response from the wearer. The power mode switch time is 3 seconds.

Design & Display
The case is made from a zirconium-based amorphous alloy with a hard-coated surface. The bezel uses nano-crystalline ceramic, and the display is protected by sapphire glass. The Blue and White Fluoroelast model ships with a wave-textured fluoroelastomer strap.
The 1.5-inch LTPO display reaches a peak brightness of 3,500 nits, maintaining readability in direct sunlight. The watch's charging solution is the HUAWEI WATCH Wireless SuperCharger, second generation, which is included in the scope of delivery.

Battery & Charging
Under typical use the watch delivers up to 6 days of battery life, extending to up to 11 days in light-use mode. With always-on display active, battery life is up to 4 days. When paired with Android under typical use, the watch lasts up to 4.5 days, or up to 3 days with always-on display. When paired with iOS under typical use, it lasts up to 3.5 days, or up to 2.5 days with always-on display.
Fifteen minutes of fast wireless charging prepares the watch for a full day of use. The included charger is the HUAWEI WATCH Wireless SuperCharger, second generation.
