Huawei Watch GT 3 Pro vs Samsung Galaxy Watch Ultra
The Verdict
Both smartwatches excel at health tracking with identical core sensors (ECG, SpO2, skin temperature, heart rate, sleep monitoring), but they target different users. Huawei Watch GT 3 Pro delivers exceptional battery longevity at 14 days, titanium construction, a sharp 466x466 AMOLED display, and costs $369. Samsung Galaxy Watch Ultra justifies its $649.99 premium with superior durability (10ATM vs 5ATM, MIL-STD-810H certification), brighter display reaching 3000 nits, cellular connectivity, WiFi, and 60-hour battery in power-saving mode. The Exynos W1000 processor with 2GB RAM provides noticeably faster app performance and smoother Wear OS 5 experience compared to Huawei's custom SoC. If battery endurance matters most and you accept HarmonyOS limitations, the GT 3 Pro offers remarkable value. However, the Galaxy Watch Ultra's enhanced durability, connectivity options, and performance justify the higher price for those wanting a rugged, feature-complete smartwatch that doubles as a standalone device. Choose Huawei for longevity and budget consciousness; select Samsung for capability and toughness.
