What we like about Amazfit GTR 3

  • Exceptional battery life, often lasting 7 to 21 days depending on usage
  • Bright and vibrant AMOLED touchscreen display with high outdoor visibility
  • Premium, lightweight aluminum design that is comfortable for 24/7 wear
  • Extensive fitness tracking with over 150 sports modes and automatic detection for select activities
  • Excellent value for money compared to premium competitors
  • Useful health features like 4-in-1 one-tap measuring for heart rate, SpO2, stress, and breathing
  • Reliable sleep tracking that includes data on daytime naps

What we don't like about Amazfit GTR 3

  • Limited third-party app ecosystem within the Zepp OS store
  • Occasional software bugs, including patchy notifications and spontaneous restarts
  • Inconsistent sensor accuracy, particularly for heart rate during high-intensity interval training (HIIT)
  • Lack of advanced smartwatch features such as NFC for mobile payments or on-board speaker for calls (non-Pro model)
  • Zepp companion app can be unintuitive and difficult to navigate
  • Flimsy magnetic charging cable that can be easily knocked out of place

Verdict

The Amazfit GTR 3 is a sleek smartwatch featuring a 1.39-inch AMOLED display with 1,000 nits brightness and a lightweight aircraft-grade aluminum alloy body. It excels in endurance with an advertised 21-day battery life and comprehensive health tracking through its BioTracker 3.0 sensor, which monitors heart rate, SpO2, stress, and sleep stages across over 150 sports modes. Key advantages include its vibrant always-on display, accurate five-satellite GPS, 5 ATM water resistance, and the intuitive Zepp OS with a physical navigation crown. However, it lacks a built-in speaker and Wi-Fi, meaning it cannot support Bluetooth phone calls or onboard music storage, and its third-party app ecosystem remains limited compared to major competitors.
