Amazfit GTS 4 vs Apple Watch Ultra (1st Gen)
The Verdict
Amazfit GTS 4 delivers exceptional value for casual fitness tracking at $199, featuring a lightweight 27g aluminum design with 8-day battery life and AMOLED display. Apple Watch Ultra commands a premium $799 price with titanium construction, comprehensive health sensors including ECG and skin temperature, and extended 36-hour battery with Low Power Mode. Ultra's cellular connectivity, NFC payments, and advanced health metrics make it superior for serious athletes and outdoor enthusiasts requiring scuba certification. GTS 4 excels for budget-conscious users prioritizing battery longevity and essential tracking. Both offer GPS and heart rate monitoring, but Ultra's ecosystem integration, durability standards, and feature completeness justify its cost for power users. For most consumers, GTS 4 represents smarter spending; for those embedded in Apple's ecosystem or needing professional-grade durability, Ultra is the justified choice.
