Huawei says the Watch GT 6 series can estimate cycling power from the wrist, cutting out £800 hardware and bringing structured training to more riders. The company pairs that promise with dual-frequency GPS, titanium and sapphire materials on the Pro, and battery life rated up to 21 days. Real-world accuracy for power, heart rate, and positioning will need independent testing before any verdict.
Designer: Huawei
Huawei says it is the first smartwatch with built-in wrist-based cycling power estimation (claims require verification against Garmin, COROS, and Polar offerings). The technology aims to lower the cost barrier for power-based training. Where traditional power meters require expensive crank arms, pedals, or hub installations, the GT 6’s virtual power system operates exclusively through wrist-worn sensors and intelligent data processing.
Built for the Demands of Serious Training
The GT 6 series targets athletes who demand reliability in challenging conditions. Huawei addresses this through materials engineering on the Pro model: sapphire crystal protects the 1.47-inch AMOLED display from scratches that would render lesser screens unreadable, while aviation-grade titanium construction resists the impacts and temperature extremes that destroy plastic fitness trackers. The nano crystal ceramic rear housing promises comfort during extended wear without the skin irritation common to metal backs.
This durability focus extends to battery endurance, where Huawei claims a decisive advantage. The GT 6 Pro’s 21-day battery life eliminates charging anxiety during multi-day training camps or remote adventures where power access becomes limited. Even the standard GT 6 models promise 12-14 days of operation, reducing the charging frequency that makes competing watches impractical for serious training schedules.
Display visibility receives equal attention through peak brightness designed for direct sunlight readability. Outdoor cyclists and runners need instant access to power data, navigation, and heart rate metrics without squinting or seeking shade. The AMOLED technology provides the contrast and color accuracy necessary for quick data interpretation during high-intensity efforts.
Comprehensive Health Monitoring Without Extra Hardware
The TruSense sensor system is designed for chest-strap-level accuracy without additional hardware. The comprehensive monitoring combines heart rate tracking with an accelerometer, gyroscope, compass, and barometer to deliver what Huawei positions as professional-grade physiological data. Blood oxygen monitoring, skin temperature tracking, and ECG functionality may expand this capability, though regional availability including the UK requires confirmation.
This sensor fusion powers the wrist-based cycling power estimation that eliminates expensive hardware barriers to structured training.
Training Independence Through Smart Connectivity
Dual-frequency GPS positioning addresses the urban signal reflection and forest canopy interference that breaks competitor navigation systems. This enhanced route fidelity becomes essential for cyclists training in challenging environments where accurate distance and elevation data directly impact training load calculations and performance analysis.
The connectivity package extends to on-device music storage and offline mapping capabilities that reduce smartphone dependency during training. Call functionality through the built-in microphone and speaker system allows communication without removing gloves or stopping mid-ride, while NFC payment support enables convenience store stops without carrying additional devices.
How It Stacks Up Against Garmin and Apple
HarmonyOS 6.0 with cross-platform compatibility through the Huawei Health app represents a strategic counter to Apple’s ecosystem lock-in. Android, iOS, and EMUI device compatibility ensures the watch remains useful regardless of smartphone choice, while data export to third-party analysis platforms preserves training history even outside Huawei’s ecosystem.
The £229-£329 pricing of the Huawei GT 6 undercuts Apple Watch Series 11, which starts at $399/USD on Apple’s website. Meanwhile Apple Watch Ultra 3 begins at $799/USD. This pricing still gives Huawei a strong advantage for structured training features at a much lower entry point.
Launch timing on September 19, 2025, places the GT 6 series in direct competition with autumn fitness technology releases, though final specifications including dimensions, weight, water resistance ratings, and charging details remain unconfirmed pending independent verification.
What Virtual Power Means for Your Training
A typical crank-based power meter costs £700-£900, with pedal-based systems like Garmin Vector 3S starting around £450 for single-leg measurement. Adding sensors and installation often complicates bike setup, requiring specific crank compatibility or professional fitting. Wrist-based power estimation avoids that complexity entirely, though it may sacrifice some precision during steep climbs where gradient calculations become less reliable.
The GT 6’s virtual calculation processes GPS-derived speed, barometric altitude changes, rider weight profiles, and bike-specific resistance characteristics simultaneously. For structured training, this could enable power-based intervals, Functional Threshold Power tests, and training load distribution analysis without additional hardware expenses or compatibility headaches.
Huawei claims up to 98% cycling accuracy and 95% trail running precision versus chest straps in internal company testing, though the testing methodology, sample size, and independent verification remain undisclosed. The system promises integration with established cycling workflows through route importing, power-based coaching guidance, and data export to platforms like TrainingPeaks and Strava.
Independent testing against dedicated power meters across varied terrain, rider weights, and bike configurations will determine whether virtual power estimation can truly serve serious training applications.
Why GPS Finally Matters in City Riding
Urban riders often run into broken GPS tracks where tall buildings reflect signals or forests cut them off completely. Huawei tackles this with dual-frequency positioning and a redesigned antenna system. In practical terms, that means your distance tracking and route maps should stay accurate in places where single-band watches drift off course.
The company claims a 20 percent accuracy gain over its previous generation, but what matters is how that translates for cyclists and runners. Better route fidelity allows more reliable gradient tracking, which in turn gives immediate feedback on climbing performance. For athletes using structured training plans, accurate elevation and distance data keep training load calculations from being skewed.
Huawei hasn’t yet confirmed which satellite constellations the GT 6 supports, and that detail could determine whether the improvement holds consistently across different geographies. Once tested, though, this approach could help the GT 6 avoid the classic frustrations of broken GPS segments in city canyons or wooded trails.
Heart Rate Reliability for Training Zones
Training effectiveness depends on accurate heart rate data during different intensity zones, from recovery rides to threshold efforts. The TruSense system promises chest-strap accuracy without additional hardware, crucial for cyclists who rely on heart rate zones to guide interval training and recovery periods.
Huawei claims 98% accuracy during cycling activities and 95% precision for trail running in internal tests, though testing conditions and methodology remain undisclosed. The heart rate monitoring extends beyond basic fitness tracking through medical-grade pulse wave arrhythmia analysis, designed to catch irregularities that could affect training safety.
The system integrates heart rate data with comprehensive wellness monitoring through Health Insight summaries that combine sleep quality, workout intensity, and recovery metrics into actionable guidance. For structured training programs, this holistic approach could help athletes balance training load with adequate recovery.
Our review will validate heart rate accuracy against chest strap monitors across multiple sport activities and intensity zones to determine real-world reliability for training applications.
Battery Life That Matches Your Training Schedule
Huawei claims the GT 6 Pro delivers up to 21 days of battery life, with the standard GT 6 promising 12-14 days depending on size. In real outdoor use with GPS tracking, heart rate monitoring, and music playback active, battery life will likely be lower – but even at half those figures, the GT 6 would outlast most competitors significantly.
For comparison, Garmin’s Forerunner 965 manages roughly 23 days in smartwatch mode but drops to 31 hours with GPS and music. Apple’s Watch Series 10 requires daily charging under normal use. The GT 6’s extended endurance could eliminate charging anxiety during multi-day training camps or remote adventures where power access becomes limited.
The extended performance comes from what Huawei describes as high-silicon stacked custom-shaped battery technology that maximizes energy density within the watch’s design parameters. Charging specifications, including cable type and time to reach usable levels, require verification through independent testing.
Premium Construction
Athletic training environments test wearable durability through temperature extremes, impact exposure, and moisture challenges that destroy consumer electronics. The Huawei Watch GT 6 Pro combines sapphire glass front protection with aviation-grade titanium construction and nano crystal ceramic rear housing, designed for scratch resistance, impact protection, and skin comfort during extended athletic wear.
Display brightness reaches a claimed 3,000 nits peak output for direct sunlight readability, though this figure awaits independent confirmation. The GT 6 Pro measures 1.47 inches diagonally with AMOLED technology, representing a 5.5% screen size increase over the previous GT 5 Pro generation.
Beyond Training: Daily Commuting and Smart Features
For everyday use, the GT 6 faces significant app ecosystem limitations compared to Apple Watch or Wear OS devices. While HarmonyOS 6.0 handles notifications, calls, and music playback competently, the third-party app selection remains sparse. You won’t find Spotify offline downloads, Uber summoning, or banking apps that make Apple Watch indispensable for urban commuting.
However, the GT 6 covers essential daily functions effectively. NFC payments work through Huawei Pay where supported, though coverage lags behind Apple Pay or Google Pay acceptance. Music storage handles MP3 files directly, useful for gym sessions or runs without phone dependency. Call handling through the built-in microphone and speaker system allows hands-free conversations during dog walks or commutes.
Cross-platform compatibility through the Huawei Health app ensures Android, iOS, and EMUI users can sync fitness data and receive notifications regardless of phone choice. This versatility matters for users who switch devices frequently or prefer not to be locked into Apple’s ecosystem. The trade-off comes in notification reply functionality on iOS, which remains limited compared to native Apple Watch integration.
Competitive Positioning
Huawei positions the GT 6 series directly against premium fitness wearables including Garmin’s Forerunner 965 at £449 and Apple’s latest lineup, where the Watch Series 11 starts at $399 and the Watch Ultra 3 at $799. The company emphasizes longer battery life, cycling-specific metrics, and lower entry pricing as key differentiators in a market dominated by ecosystem lock-in and high-end performance features.
Market growth figures shared by Huawei, such as rising adoption among non-Huawei smartphone users in the UK and year-over-year share gains, remain unverified and should be treated cautiously until confirmed by independent reporting. What matters most for competitive athletes is whether the GT 6 can consistently deliver reliable power data across diverse riding conditions.
The crucial test is accuracy. If wrist-based power estimation proves dependable in real-world use, it could make structured training accessible to far more cyclists. Our review will measure how well the GT 6 performs against established hardware across terrain, rider weights, and intensities to see if it can stand as a genuine alternative to dedicated power meters.
