The Amazfit GTR 4 offers something many smartwatches struggle to balance: a traditional round-watch appearance, advanced fitness tracking, onboard GPS, Bluetooth calls, and battery life measured in days rather than hours.
It is not the newest model in Amazfit’s catalog, but its official feature set remains competitive for buyers who want strong exercise tools without entering a more expensive smartwatch ecosystem.
Value verdict: The GTR 4 is a strong option for users who prioritize battery endurance, sports tracking, and classic styling over a massive third-party app library.
The Seven-Day Challenge
Imagine using the GTR 4 through a normal week without reaching for the charger. Its official battery estimate reaches up to 14 days under a typical-use scenario and approximately seven days under heavier use. Actual endurance varies with GPS, brightness, notifications, calling, health monitoring, and the always-on display.
Monday: Start with the Display
The watch uses a 1.43-inch AMOLED panel with a 466 × 466 resolution and a density of 326 pixels per inch. Anti-glare treatment on the bezel and an anti-fingerprint coating help keep the display easier to view and cleaner during daily wear.
More than 200 watch faces are available, including animated, interactive, and always-on options. Users can also upload personal images for additional customization.
Tuesday: Record a Strength Session
The GTR 4 supports more than 150 sports modes. Its strength-training mode can recognize movements, count repetitions for supported exercises, record rest periods, and organize exercised muscle groups inside the Zepp application.
Automatic recognition is available for eight activities, including walking, outdoor running, treadmill use, cycling, rowing, elliptical training, and pool swimming.
Wednesday: Test the GPS
Dual-band circularly polarized GPS technology is one of the model’s standout features. The watch supports multiple satellite-positioning systems and can import route files from the Zepp application for real-time route guidance.
| GPS mode | Official maximum estimate |
|---|---|
| Accuracy mode | Up to 25 hours |
| Balanced mode | Up to 44 hours |
| Power-saving mode | Up to 52 hours |
Higher-accuracy modes consume more energy. The appropriate setting depends on whether the activity requires the strongest possible positioning or the longest possible endurance.
Thursday: Review Health Trends
The BioTracker 4.0 PPG sensor supports continuous heart-rate, blood-oxygen, and stress monitoring when the relevant settings are enabled. A one-tap measurement can also estimate heart rate, SpO2, stress, and breathing rate in one session.
The watch can track sleep stages, daytime naps, sleep schedules, and sleep-breathing quality. Morning Update can display a customizable summary containing weather, battery, sleep, schedule, activity, and other information.
Amazfit states that the device and Zepp application are not medical devices. Measurements are intended for reference and should not be used to diagnose a health condition.
Friday: Leave the Phone in Your Pocket
A built-in microphone and speaker allow the GTR 4 to answer Bluetooth calls while connected to a compatible phone. It can also display application, SMS, and call notifications.
Android users can access quick SMS replies in supported configurations. Compatibility and availability may depend on the phone, Zepp application version, country, and software.
Saturday: Add Music and Navigation
Music files can be stored on the watch for direct playback through Bluetooth headphones. Users can also control music playing from a connected phone.
Amazon Alexa support provides online voice assistance in supported regions, while the offline voice assistant can open sports modes and selected watch features without an internet connection.
Sunday: Swim and Recover
The GTR 4 carries a 5 ATM water-resistance rating and can record pool-swimming information. Amazfit describes this as resistance to pressure equivalent to approximately 50 meters, but users should follow the manufacturer’s care guidance and avoid treating the rating as permission for every water activity.
Design and Wearing Experience
The case uses an aluminum-alloy middle frame with a traditional round shape and a stainless-steel navigation crown. Strap options have included black fluoroelastomer, brown leather, and gray nylon, each giving the watch a different personality.
| Strap | Best use |
|---|---|
| Fluoroelastomer | Exercise and swimming |
| Leather | Office and business-casual wear |
| Nylon | Travel and lightweight comfort |
