The Huawei Watch GT 6 Pro, unveiled in Paris, is Huawei’s latest premium wearable, continuing the tradition of the Watch GT family which draws inspiration from high-speed, long-distance Gran Turismo cars. Positioned as a superb sports watch beautifully disguised as a premium smartwatch, the GT 6 Pro excels in durability, fitness tracking, and—most notably—battery endurance.

Starting at £329, the Watch GT 6 Pro attempts to deliver elite-level performance without the bulky aesthetic typically associated with hardcore sports trackers.

Premium Design and Outstanding Display

Huawei maintains its reputation for delivering classy smartwatch design with the GT 6 Pro. It is available only in a single 46 mm size, though reviewers found it surprisingly manageable and not “ridiculously oversized”.

World-Class Build Quality

The watch leverages high-end materials for maximum durability:

• Screen: Sapphire glass. Sapphire is one of the hardest materials on earth, scoring 9 on the Mohs scale (just below diamond’s 10 Mohs). It is stiff and almost impossible to scratch.

• Body: Titanium alloy frame/body, sometimes featuring an ultra-hard metallic coating.

• Back: Ceramic casing, which is hypoallergenic and ideal for sensor placement.

• Water Resistance: The GT 6 Pro is rated IP69 dust and water resistant and can survive pressures up to five atmospheres (5ATM). Huawei specifically rates it for 40m swimming and diving (EN13319), suitable for activities like pool swimming and freediving.

Bright and Crisp Screen

The GT 6 Pro features an updated 1.47-inch AMOLED display. The screen surface is slightly bigger than the previous generation, and the bezel has been reduced by 10%. Crucially, the display reaches an impressive peak brightness of around 3,000 nits. This level of brightness ensures that the screen remains clearly visible even under direct outdoor sunlight. The screen’s clarity means tiny text is perfectly legible.

Serious Fitness and Health Features

This is the area where the Watch GT 6 Pro truly shines, delivering performance comparable to dedicated sports watches. It features an upgraded TruSense health monitoring system.

Comprehensive Tracking and Accuracy

The watch tracks all the obligatory health statistics, including heart rate, SpO2 levels, skin temperature, and emotional well-being. New additions include Heart Rate Variability (HRV) support which is a key indicator for assessing physical health and recovery. The device is also ECG certified and can assess the elasticity of your arteries.

Heart Rate Accuracy Breakdown:

• Indoor Cycling/Spinning: Excellent, achieving near chest-strap level accuracy in steady states and tempo efforts.

• Outdoor Running: Generally good, though expect a short lag (a few seconds) when heart rate ramps quickly, such as during sprints or steep hills. Overall averages and zone tracking are trustworthy.

• Outdoor Cycling: Solid overall, but minor drift may occur on bumpy roads or long descents due to vibration and reduced muscle pump affecting the PPG signal. For highly precise interval timing or racing efforts, using a paired Bluetooth chest strap is recommended.

Advanced Cycling and Outdoor Modes

Huawei has placed a significant focus on outdoor cycling features. The GT 6 Pro is the first watch to feature a ‘virtual power’ metric, which uses advanced algorithms to estimate a cyclist’s power output, including Functional Threshold Power (FTP).

Outdoor enthusiasts also benefit from:

• Offline Map Support: Users can load cycling routes via Huawei’s Petal Maps app.

• Golf Mode: Updates allow tracking the distance to nearest obstacles like lakes on the course map.

• Skiing: Updates allow tracking up to 100 runs in total.

• GPS: The upgraded Sunflower positioning system is generally quick to find location, usually within a few seconds.

Sleep Tracking and Recovery Insights

The GT 6 Pro offers detailed sleep tracking, recognizing different sleep stages based on heart rate, SpO2, and movement patterns. The accompanying Huawei Health app provides a sleep score, rankings for sleep stages, and a written breakdown with actionable advice. This user-friendly approach stands out among smartwatches.

The Smartwatch Compromise: HarmonyOS Limitations

The GT 6 Pro runs on HarmonyOS 6.0, which provides a visually vibrant and crisp experience. However, the software limitations represent the most significant drawback compared to rivals.

• App Ecosystem: The Harmony ecosystem remains small, especially outside of China. Users accustomed to a wide array of apps may find this lacking.

• Contactless Payments: There is currently no functional contactless payment support (NFC payments) for regions like the UK/Blighty. The wallet app is pre-installed but often lacks card connectivity outside certain regions.

• Notification Handling: Notifications are received, but interactivity is limited. While users can reply to messages (e.g., on WhatsApp or Facebook Messenger) using preset responses or a functional on-screen keyboard, they cannot see images, respond to emails, or delete emails from the phone via the watch.

• Voice and Calls: A major positive is the quality of the built-in mic and speaker, allowing for excellent voice calls directly from the watch, even in noisy environments.

Battery Life: The Endurance Champion

The battery life is one of the GT 6 Pro’s biggest selling points, often being far superior to most other rivals. This leap in longevity is due to the adoption of new high-silicon/silicon-carbon battery technology, increasing capacity by roughly 65% compared to the GT 5 Pro. The battery capacity is 867 mAh.

• Advertised Longevity: Huawei claims up to 21 days (three full weeks) of battery life with light usage, and 12 days for typical usage.

• Real-World Performance: Even with demanding usage—including the always-on display active, constant health tracking, notifications, and 30 minutes to over an hour of activity tracking daily—reviewers consistently achieved 10 solid days of battery life from a single charge. Another test showed 9 days with AOD on and multiple workouts.

• Charging: Charging takes approximately one hour and a half (90 minutes) to reach 100%. Since charging is infrequent, this speed is not considered a major issue.

Verdict: Should You Buy the Huawei Watch GT 6 Pro?

The Huawei Watch GT 6 Pro is a compelling option for those who prioritize fitness tracking, premium build quality, and extreme battery life above all else.

It delivers an elite-level sports tracking experience, particularly for runners and cyclists who want dependable zone tracking and accurate averages. The physical design, featuring sapphire glass and titanium, is undeniably premium.

However, prospective buyers must be prepared for the significant compromises in smart features, namely the lack of robust third-party apps, limited notification interactivity, and the absence of contactless payment support outside certain regions.

If you are seeking a long-lasting, tough, good-looking sports watch with essential smart features, the GT 6 Pro is a “no-brainer”. If you require features like Google Assistant, offline Spotify support, or wrist-based payments, W OS or Apple Watch rivals may be a better fit.
