Huawei Watch GT 5 Pro 42 mm specifications and in-depth review

Huawei Watch GT 5 Pro 42 mm

Manufacturer: Huawei

The Huawei Watch GT 5 Pro 42 mm is a compact smartwatch built around a 1.32″ OLED/AMOLED panel with a resolution of 466 x 466 px and a pixel density of 326 ppi. It features sapphire glass protection, an Always-On Display, and a touch-sensitive interface, all housed in a 42.5 x 42.5 mm case that weighs just 44 g and measures 9.6 mm thick. The band is replaceable at a width of 20 mm, and the watch is rated at 5 ATM with a waterproof depth of 50 m, making it suitable for both diving and golf activities.

On the health and connectivity side, the watch includes a heart rate monitor, pulse oximeter, body temperature sensor, ECG technology, gyroscope, barometer, compass, and accelerometer. Built-in GPS with Galileo support enables route tracking and elevation monitoring, while Bluetooth 5.2, Wi-Fi 4, and NFC round out the wireless feature set. The 323 mAh battery offers up to 4 days of use and supports wireless charging. The companion app — free and ad-free — covers sleep tracking, activity reports, calorie counting, BMI tracking, water intake, goal setting, ovulation prediction, live tracking, and music playback, among other functions.

Pros
  • Sapphire glass display offers strong scratch resistance for everyday wear
  • Comprehensive health monitoring includes ECG, pulse oximeter, heart rate tracking, and body temperature sensor
  • Built-in GPS with Galileo support enables accurate route and elevation tracking without a paired phone
  • The companion app is both free and ad-free, with a wide range of tracking and personalisation options
  • Waterproof to 50 m with a 5 ATM rating, and specifically designed for diving and golf
  • Wireless charging removes the need for a physical charging cable
Cons
  • Battery life of only 4 days is relatively short for a GPS-equipped smartwatch
  • No cellular module means the watch depends on a paired phone for connectivity
  • Multi-sport mode is absent, limiting structured workout variety
  • Fall detection and smart alarm are not supported
  • Not compatible with Windows or Mac OS X, restricting desktop sync options
  • Fast GPS lock is not available, which may slow positioning in outdoor activities
Who is this for?

This watch is well suited to health-conscious users who want thorough biometric monitoring on their wrist, given its ECG, pulse oximeter, body temperature sensor, and continuous heart rate tracking. It is a strong fit for outdoor and fitness enthusiasts who rely on built-in GPS, elevation tracking, route support, and automatic activity detection during activities like hiking or running. The dedicated diving and golf modes, combined with a 50 m waterproof rating, make it particularly appropriate for users who engage in water sports or on-course play. Those who also value reproductive health tracking will find the ovulation prediction, fertile window notifications, and period tracking features directly useful.

Who is this NOT for?

Users who need cellular independence — such as those who want to leave their phone behind during workouts or outdoor sessions — will find this watch limiting, as it lacks a cellular module. The 4-day battery life may not satisfy users who prioritize extended off-grid use or multi-day expeditions without access to charging. Athletes who rely on structured multi-sport training sessions may be frustrated by the absence of a dedicated multi-sport mode. The watch is also not a good fit for those who need desktop connectivity with Windows or Mac OS X, as neither platform is supported for syncing or configuration.
