Amazfit GTR 4 vs Apple Watch Ultra (1st Gen)
The Verdict
Amazfit GTR 4 delivers exceptional value with a 14-day battery life, vibrant 1.43-inch AMOLED display, and comprehensive health tracking including SpO2 and heart rate monitoring. Apple Watch Ultra 1st Gen commands a 4x price premium at $799, justifying costs with titanium construction, advanced health features (ECG, skin temperature), cellular connectivity, and superior 36-hour battery with Low Power Mode extending to 60 hours. Processor performance heavily favors Apple's S8 SiP, enabling richer app ecosystem and faster performance. Water resistance differs significantly: Amazfit offers 5ATM (50m) while Ultra achieves WR100 with scuba certification to 40m. For budget-conscious users seeking reliable daily tracking, Amazfit GTR 4 represents outstanding value. Those prioritizing comprehensive health data, cellular independence, and premium materials should invest in Apple Watch Ultra. Recommendation depends entirely on budget: GTR 4 for practical tracking under $200, Ultra for demanding athletes and always-connected users.
