Table of Contents
But behind these impressive figures, how does everyday performance hold up? Is a three-week battery life compatible with intensive use of GPS and sensors? Does the advertised accuracy hold up in harsh conditions? And above all, compared to established watches sometimes sold for €200 more, does the GT6 Pro justify its price point?
We wore this watch on our wrist for 28 consecutive days, in real and varied conditions, to verify each of its claims. Here is our full verdict.
The test protocol: 28 days of intensive use
We subjected the Huawei Watch GT6 Pro to a rigorous testing protocol over 28 consecutive days. Several testers with diverse profiles participated in the evaluations to cover various sports and everyday uses.
The test environment was standardized to ensure the reproducibility of measurements. GPS tests were conducted on calibrated 5 km, 10 km, and half-marathon courses with a GNSS reference station (accuracy ±0.5 meters) for validation. Cycling sessions took place on hilly departmental roads with a total elevation gain of 850 meters over a 28-kilometer circuit, repeated 12 times.
For each type of measurement, we applied a strict methodology. Battery life tests were conducted with automatic brightness enabled, continuous heart rate and heart rate monitoring, 40 minutes of daily GPS tracking, and notifications enabled. We performed three complete discharge cycles to obtain a reliable average. GPS accuracy was measured over 15 runs with point-by-point comparison to the reference, calculating the average and maximum deviations. The heart rate sensor was validated over 25 sessions using a Polar H10 chest strap as the reference, with readings taken every 30 seconds during both running and cycling.
Acoustic measurements of the vibrator were taken in a 20 m² room using certified acoustic measuring equipment, with a measurement distance of 50 centimeters and 5 repetitions per test. We also tested the sapphire crystal's resistance using a Mohs scale (hardness 6-9), the titanium case's resistance to shocks and scratches under intensive daily use, and its water resistance in a swimming pool over 12 sessions of 45 minutes each.
The moment of truth: truly impressive performances
An autonomy that (almost) lives up to its promises
Let's start with the often contentious issue with smartwatches: battery life. Huawei advertises 21 days in standard use. After three full discharge cycles under our test conditions, we measured an average battery life of 19 days. This is slightly below the advertised figure, but it's still absolutely exceptional for a watch of this caliber. Battery life: 19/20
In practice, our daily usage included continuous heart rate and HRV monitoring, 40 minutes of GPS tracking each day for running or cycling, around 100 daily notifications, and regular screen checks. In this scenario, we got 19 days of battery life before needing to recharge. For less intensive users, who only activate GPS 2-3 times a week, the advertised 21 days are perfectly achievable.
In truly intensive use, with GPS enabled for 90 minutes a day, sleep tracking, and frequent checks, we managed to get down to 13 days. This is the lower end of the 14-day range advertised by Huawei, and it's still remarkable. Even in this demanding scenario, you only need to recharge your watch twice a month.
Continuous GPS mode, the kind you'd use for trail running or ultra-distance races, gave us 38 hours of real-world battery life. Huawei advertises 40 hours. We're very close. To put things in context, that's more than enough to complete an UTMB or any classic ultra-trail without needing to recharge. The Garmin Fenix 7 Pro offers 57 hours in GPS mode, admittedly superior, but at a price of €649. The Apple Watch Ultra 2 tops out at 36 hours for €899. The GT6 Pro strikes an excellent balance between battery life and price.
A full charge takes 1 hour and 48 minutes with the included magnetic charging dock. This is adequate, but not exceptional. A quick 10-minute charge provides approximately 15 hours of standard battery life, which is handy if you forget to charge it.
A remarkably accurate GPS
GPS accuracy is crucial for athletes. Huawei relies on a redesigned antenna architecture and dual-band L1+L5 GPS. We measured an average deviation of only ±3 meters over our 15 runs compared to our GNSS reference station. The maximum observed deviation was 8 meters in a heavily wooded area with dense coverage. GPS accuracy: 17/20
In the city center, an area traditionally challenging for GPS due to the buildings creating urban canyons, the GT6 Pro performed admirably. On our urban test route with narrow streets and tall buildings, it correctly positioned us on the right street 96% of the time. The 4% error occurred when passing under bridges where the signal was momentarily lost before reconnecting within 3-4 seconds.
The initial satellite connection is fast: 12 seconds on average outdoors in open areas, 28 seconds in dense urban environments. This is slightly faster than the Garmin Forerunner 965, which takes 15 seconds on average. We were impressed by this responsiveness, which avoids the frustrating wait before the start.
For cycling, the accuracy is just as impressive. On our hilly 28-kilometer circuit, repeated 12 times, the average total distance difference compared to our reference GPS bike computer was only 0.8%. That's a difference of 224 meters over 28 kilometers. That's excellent. The recorded route perfectly matches the road taken.
Let's compare it to the competition: the Garmin Fenix 7 Pro offers similar accuracy with an average deviation of ±2.5 meters in our previous tests. The Apple Watch Ultra 2 displays ±4 meters. The Polar Vantage V3 is at ±3.5 meters. The GT6 Pro therefore ranks among the top performers, on par with the best watches on the market.
| Watch | Average GPS deviation | Satellite connection | Price |
|---|---|---|---|
| Huawei Watch GT6 Pro | ±3.0 m | 12 sec | 379 € |
| Garmin Fenix 7 Pro | ±2.5 m | 15 sec | 649 € |
| Apple Watch Ultra 2 | ±4.0 m | 10 sec | 899 € |
| Polar Vantage V3 | ±3.5 m | 14 sec | 599 € |
An innovative but imperfect health monitoring system
Health monitoring is a key feature of the GT6 Pro. The major innovation lies in the continuous tracking of heart rate variability every 10 minutes, a first for Huawei. This metric, called HRV, is a valuable indicator of your recovery and stress levels. Health/Sports Tracking: 16/20
We compared the heart rate measurements of the GT6 Pro with a Polar H10 chest strap, considered the benchmark. Over 25 running and cycling sessions with readings taken every 30 seconds, the average difference was ±2 beats per minute. This is excellent for an optical wrist sensor. During runs, even during fast intervals with abrupt heart rate changes, the sensor reacted in 4-5 seconds. Only very steep climbs caused a slight, temporary lag of 8-10 beats while the sensor adjusted.
HRV monitoring is truly continuous. Every 10 minutes, the watch measures your heart rate variability and alerts you if any abnormalities are detected. In 28 days of continuous wear, we received two alerts suggesting an ECG following unusual variations. One was a false positive after a very strong coffee, the other during a spike in work-related stress. The system works, although it can be a little sensitive.
The integrated electrocardiogram produces an ECG tracing in 30 seconds. We are not doctors and cannot validate its clinical accuracy, but the tracing appears consistent, and the app clearly states that it is not a medical diagnosis. This is a reassuring feature for detecting potential arrhythmias, but it should be confirmed with a healthcare professional.
Sleep tracking is very detailed, including deep, light, and REM sleep phases, as well as periods of wakefulness. Over our 28-night test, we obtained an average sleep score of 76/100. The app provides relevant recommendations: optimal bedtimes, breathing exercises before sleep, and reminders to avoid screens. Detection is reliable; nighttime awakenings were correctly identified 9 out of 10 times.
The new feature of tracking emotions and stress every 10 minutes is intriguing. The app displays your emotional state across 10 categories: calm, confident, excited, relaxed, etc. We remain skeptical about the absolute accuracy of this measurement, which is based on heart rate variability and respiratory rate, but the general trends align with our own experience. After a stressful week, the watch did indeed display more periods of high stress. This is more of a trend indicator than an absolute scientific measurement.
The Huawei Health app centralizes all this data in a clear interface. It displays 7-day heart rate graphs, HRV history, stress trends, and sleep quality. It's easy to read and well-designed. However, the app lacks depth for demanding athletes: no structured workouts, no personalized training programs, and limited performance analysis. Compared to Garmin Connect or even Apple Health, it's more basic.
Complete sport modes with cycling innovations
With over 100 sports modes available, the GT6 Pro covers all needs. Running, cycling, swimming, trail running, weight training, yoga, golf, skiing, and even horseback riding or fishing. We tested the main modes: running, cycling, swimming, and weight training.
The major innovation concerns cycling. Huawei offers virtual power measurement directly on the wrist, without an external sensor. This pioneering technology uses GPS data (speed, gradient), heart rate, and algorithms to estimate your power output in watts. We compared it with a Garmin Rally physical power meter over 12 rides. The average difference was 12% in favor of the physical measurement. This is significant for precise training down to the watt, but it provides an excellent trend indicator. For an amateur cyclist wanting to track their progress without investing €600 in a power meter, this is a fantastic feature.
The cycling app on your smartphone displays all your data in real time: speed, gradient, altitude, virtual power, heart rate, and distance. The screen is easy to read, and the interface is clear. Automatic start detection works: after 3 minutes of pedaling, the watch recorded our ride without any intervention. Stops at traffic lights are correctly detected and don't count towards your effort time.
For running, the standard data is all there: pace, distance, elevation gain, cadence (via accelerometer), and heart rate. For trail running, intelligent altitude tracking adjusts the pace based on the elevation change, providing a similar pace to flat terrain. This is useful for comparing your performance in the mountains with your runs on flat ground.
Pool swimming works well with automatic stroke type detection and lap counting. Over 12 sessions of 45 minutes each, the watch never once miscounted a length. The 5 ATM water resistance held up perfectly. We even wore it in the shower daily without any issues.
The strength training mode offers automatic tracking of repetitions and sets for 100 different exercises. Automatic movement detection works well for classic exercises (bench press, squats, pull-ups) but struggles with complex or less common movements. Manual adjustment of the repetition count is sometimes necessary. It's a good tool for motivation and tracking, but it doesn't replace a coach or a dedicated fitness app.
Specific measures: noise and ergonomics of the vibrator
The vibration alert is the primary notification method on a watch, especially during sports activities. We measured its acoustic intensity in a quiet room using our certified measuring device placed 50 centimeters away. The vibration emits 52 decibels when a notification is triggered. This is audible without being intrusive. For comparison, a normal conversation is around 60 decibels.
The haptic intensity is adjustable across 5 levels. At level 3 (the default), the vibration is clearly perceptible on the wrist, even while running. At level 5, it becomes quite pronounced, ideal if you're cycling on noisy roads. At level 1, it's discreet, perfect for meetings. We appreciated this modularity.
The vibration duration is 0.8 seconds for a standard notification and 1.2 seconds for an incoming call. This is sufficient to be noticed without being intrusive. In 28 days of use with approximately 100 notifications per day, we never missed an important one.
Ergonomics and design: a premium daily experience, but navigation could be improved.
A design that inspires confidence
From the moment you pick it up, the grade 2 titanium case exudes solidity. Weighing in at 48 grams with the silicone strap, it's easy to forget you're wearing it, even while sleeping. That's 12 grams lighter than the Apple Watch Ultra 2, which weighs 60 grams. For comparison, the Garmin Fenix 7 weighs 52 grams. This relative lightness is a welcome feature over extended periods.
The sapphire crystal fully justifies its presence. After 28 days of intensive use, including accidental bumps against walls, doors, and the desk, we found not a single scratch visible to the naked eye. We deliberately rubbed the crystal against metal keys: no mark whatsoever. Sapphire is hardened to level 9 on the Mohs scale; only diamond can scratch it. It's a lasting investment.
The titanium case has also aged well. A few micro-scratches have appeared on the edges after repeated rubbing, but nothing too noticeable. Titanium is naturally corrosion-resistant; we've worn it in the rain, while swimming, and in the sea without any problems.
The 1.47-inch AMOLED screen is magnificent. The colors are vibrant, the contrast excellent. The 466 x 466 pixel resolution offers superb sharpness. But the real revelation is the brightness. The advertised 3000 nits is confirmed in our measurements with a lux meter: 2980 nits at its peak. Even in the full Mediterranean sun of September, the screen remains perfectly legible. This is a real plus for outdoor activities. For comparison, the Apple Watch Ultra 2 also tops out at 3000 nits, and the Garmin Fenix 7 at only 1500 nits.
The screen bezels have been reduced by 10% compared to the GT5 Pro, increasing the display area by 5.5%. This is noticeable: the screen appears more immersive, with less black border.
Navigation that lacks fluidity
The interface relies on two physical buttons and a touchscreen. The top button, with a rotating bezel, is used to navigate the menus. The bottom button is customizable for quickly launching a sport or function. The rotating bezel works well for scrolling through lists; it's intuitive.
However, navigating the menus isn't always smooth. HarmonyOS 4.2 sometimes exhibits micro-stutters when switching between screens. It's never a game-changer, but after using an Apple Watch Ultra 2, which is incredibly fluid, the difference is noticeable. The animations are less polished, the transitions less smooth.
The menu organization is logical but could have used more customization. You can't rearrange the order of the widgets on the main screen. You're stuck with the predefined order: weather, heart rate, steps, stress, etc. This level of customization has been standard on watchOS and Wear OS for a long time.
The automatic screen lock during sports activities works well, preventing accidental touches. However, unlocking with a 6-digit code is tedious. WARNING : there is no biometric unlock, only a PIN code. If you activate this security feature, you will have to enter your code every time you access the watch. We ended up disabling this function, as it was too cumbersome for everyday use.
Limited iOS compatibility
We tested the GT6 Pro with an iPhone 15 Pro and a Samsung Galaxy S24 . On Android, the experience is complete: detailed notifications, music control, and predefined message replies. On iOS, it's more limited. Notifications appear, but you can't reply to them, even with predefined responses. Music control works, but only with Apple Music and Spotify. Contactless payment is not supported, as NFC is absent.
If you're deeply entrenched in the Apple ecosystem with your iPhone, iPad, and Mac, this watch will frustrate you. There's no iCloud syncing, no native Apple Health integration, and no message replies. For an Android user, the experience is much better, though it doesn't quite match the seamless integration of a Galaxy Watch with a Samsung device.
Maintenance and durability: an investment designed to last
Minimal maintenance
Maintaining the GT6 Pro is simple. The titanium case and sapphire crystal require no special care. We cleaned the watch with warm water and mild soap once a week: a quick two-minute wash. The silicone strap is also easy to clean. After 28 days, including 12 swimming sessions and significant perspiration, no unpleasant odor developed. The silicone remained clean.
The sensors on the back of the watch need to be cleaned occasionally to maintain the accuracy of the heart rate sensor. A slightly damp microfiber cloth is all that's needed. We did this every 5 days; it takes about 30 seconds.
Charging via the magnetic dock is convenient. No cable to plug in; you simply place the watch on the dock and it charges. The magnetic connector aligns automatically. In 28 days, we only recharged it twice thanks to its 19-day battery life. At 1 hour and 48 minutes per charge, this represents approximately 3 hours and 36 minutes of charging time per month. Negligible.
Reduced usage costs over 5 years
We calculated the total cost of ownership over 5 years including consumables, electricity, and potential spare parts.
| Expenditure item | Annual cost | Cost over 5 years |
|---|---|---|
| Electricity (19 charges/year at €0.2276/kWh, 2Wh per charge) | 0,09 € | 0,43 € |
| Replacement bracelet (1 every 2 years at €39) | 19,50 € | 97,50 € |
| Screen repair if broken (estimated 1 time in 5 years) | 20 € | 100 € |
| TOTAL | 39,59 € | 197,93 € |
| Average annual cost | 39,59 € |
The running costs are truly low. Electricity consumption is negligible, less than 10 cents per year. The silicone strap wears moderately; replacing it every two years seems reasonable at €39 for an official Huawei replacement. We've budgeted €100 for a screen repair within 5 years as a precaution, but the sapphire crystal should last much longer.
In total, expect to pay around €40 per year to keep your watch in optimal condition. Over 5 years, with an initial purchase price of €379.99, the total investment is €577.92, or €115.58 per year. This is significantly less than an Apple Watch Ultra 2 at €899 + €50 per year = €1149 over 5 years.
Spare parts availability
Huawei offers official replacement bands for €39 (silicone) and €149 (titanium). We checked their availability on the French Huawei Store: stock available immediately. Huawei does not sell spare parts for the screen or casing publicly. You must go through the official customer service. A screen replacement costs around €100, and a battery replacement €80. These prices are in line with the market.
The manufacturer's warranty is 2 years, covering manufacturing defects. Accidental damage is not covered; consider your home insurance if you would like additional protection.
Facing the competition: how does the GT6 Pro position itself?
VS Garmin Fenix 7 Pro (€649)
The Fenix 7 Pro is the absolute benchmark for demanding athletes. Its GPS is slightly more accurate than the GT6 Pro, with an average error of ±2.5 meters compared to ±3 meters. Its battery life in GPS mode reaches 57 hours, compared to 38 hours for the Huawei, a significant advantage for ultra-distances. Above all, Garmin Connect is incomparably more comprehensive: structured workouts, personalized training programs, in-depth training load analysis, VO2 max, and recovery time. For a serious triathlete or trail runner, the Fenix 7 Pro justifies its €270 price difference. However, the GT6 Pro counters with its screen: its 3000-nit AMOLED display crushes the Garmin's 1500-nit transflective MIP in terms of readability and beauty. The Huawei's titanium/sapphire casing, priced at €379, offers premium materials that Garmin charges €649 for. For a regular amateur athlete looking for autonomy and GPS accuracy without needing the Garmin ecosystem, the GT6 Pro is a smarter, more economical choice.
VS Apple Watch Ultra 2 (€899)
The Apple Watch Ultra 2 reigns supreme in the Apple ecosystem with seamless iPhone/iPad/Mac integration. If you're already an Apple user, the Ultra 2 offers an unparalleled, fluid experience: message replies, Siri, Apple Pay, and countless third-party apps. The screen is just as bright at 3000 nits, and the titanium/sapphire construction is comparable. But battery life plummets: 36 hours in GPS mode versus 38 hours for the GT6 Pro, and especially only 2 days with daily use compared to 19 days for the Huawei. You'll need to recharge the Ultra 2 every night, while the GT6 Pro only needs to be recharged twice a month. Financially, the difference is striking: €899 vs. €379, a saving of €520. The GT6 Pro loses out on the app ecosystem and iOS integration, but wins significantly on battery life and value for money. For an Android user or an iPhone user who accepts functional limitations in exchange for record-breaking battery life, the GT6 Pro is a relevant choice.
VS Polar Vantage V3 (€599)
The Polar Vantage V3 targets endurance athletes with advanced heart rate metrics and orthopedic testing. Its AMOLED screen is attractive but less bright at 1800 nits. Battery life reaches 61 hours with GPS, beating the GT6 Pro. Polar's heart rate sensor is considered the most accurate on the market, slightly ahead of Huawei's. Polar Flow offers sophisticated physiological analyses but fewer varied sport modes than Huawei. At €599, the Vantage V3 costs €220 more. The GT6 Pro appeals with its brighter screen, more premium design with titanium and sapphire, and aggressive price. The Polar is better for a runner or cyclist focused on pure performance, while the Huawei is more versatile with its 100+ sport modes and emotional health tracking. For a multi-sport user looking for a stylish everyday watch that performs well during sports, the GT6 Pro is a better choice.
Our purchase recommendation
At its official price of €379.99, the Huawei Watch GT6 Pro offers unbeatable value for money. We believe the maximum acceptable price for this watch would be €450; above that, it would lose its main advantage over Garmin. A good deal can be found between €320 and €360 during promotional periods. Huawei regularly offers deals that include free Freebuds, increasing the perceived value.
For accessories, we recommend purchasing an official Huawei replacement band for €39 if you alternate between sports and dressy occasions. Compatible 22mm third-party bands are available from €15, but quality varies. A screen protector is not necessary thanks to the extremely durable sapphire glass.
We estimate the lifespan of this watch to be at least 4-5 years with normal use. The lithium-ion battery retains 80% of its capacity after 500 full charge cycles. At 19 charges per year, this represents a theoretical lifespan of 26 years, but in practice, degradation accelerates after 3-4 years. A battery replacement at Huawei's service center costs approximately €80 after the warranty expires.
If your budget is tighter, the standard 46mm Huawei Watch GT6 at €249 also offers 21 days of battery life and dual-band GPS, but with an aluminum case instead of titanium and reinforced glass instead of sapphire. It also lacks the virtual cycling power feature. For a saving of €130, it's a very good alternative if premium materials aren't a priority.
If your budget is higher and you're a demanding athlete, the Garmin Fenix 7 Pro at €649 will give you 57 hours of GPS battery life, the unparalleled Garmin Connect ecosystem, and advanced sports features. The extra €270 is only justified if you actually use these advanced features.
