The bit that actually impressed me
My mate Dave switched from a Garmin to the GT 5 last month and the first thing he said was: the battery. Not the screen, not the health tracking. The battery. Huawei claims around two weeks of use, and he's been getting close to that in practice. For most smartwatches that's borderline unheard of. Wear it on a Tuesday, charge it the following Thursday. Proper liberating once you're used to it.
The 46mm case looks sharp too. Metal and sapphire crystal glass, so it doesn't feel like a toy on your wrist. The AMOLED display is bright and clear even in decent sunlight, which isn't always a given at this price point.
Where it gets complicated
Here's my honest reservation, and it matters depending on your phone setup. If you're on iPhone, the experience is noticeably clipped. Huawei's Health app on iOS doesn't play as nicely as it does on Android, and you'll lose some features. Android users get the fuller picture.
Also worth knowing: no Google Play, no third-party apps beyond Huawei's own ecosystem. For fitness tracking, sleep, workouts and notifications it's spot on. But if you want Spotify controls or Citymapper on your wrist, look elsewhere.
Who this is actually for
Android users who want long battery life, a good-looking watch, and solid health metrics without paying Apple or Samsung prices. Runners especially will appreciate the GPS accuracy and the workout modes. Not for iPhone loyalists, not for app hoarders. But if your priorities are battery and build quality, this is not half bad at all.
