If you want a classic round watch with a bright AMOLED display, strong GPS, extensive workout modes, and battery life measured in weeks rather than hours, the Amazfit GTR 4 smartwatch remains an appealing value-focused option. It combines dual-band positioning, health and sleep tracking, Bluetooth calls, music storage, Alexa, and a 46mm design that looks more like a traditional watch than a small phone on the wrist. This review focuses on the Superspeed Black standard model.

Amazfit GTR 4 smartwatch design and AMOLED display
The Amazfit GTR 4 smartwatch uses a 46mm round case with an aluminum alloy middle frame, a stainless-steel navigation crown, and a second physical button. The Superspeed Black model pairs the case with a black fluoroelastomer strap, while other GTR 4 variations use leather or nylon. At approximately 34 grams without the strap, the watch gives you a large display without becoming excessively heavy for a full-size sports smartwatch.
The 1.43-inch HD AMOLED display has a 466 by 466 resolution and 326 pixels per inch. Its anti-glare bezel treatment and anti-fingerprint coating help keep the screen more readable during everyday use, while more than 200 watch faces and matching always-on displays make the watch easy to personalize. The display is bright enough for workouts and notifications, but an always-on screen can reduce endurance compared with a wrist-raise-only setting.
What the Amazon configuration includes
Amazon identifies the product as the Amazfit Smart Watch GTR 4 with Zepp OS, 2.3GB of memory storage, a 475mAh battery, Bluetooth 5.0, GPS, phone calls, stress tracking, and a 1.43-inch screen. The standard package includes the watch with its standard strap, magnetic charging cable, and instruction manual. Because the listing can include multiple colors and related GTR 4 variations, confirm that the selected option is the standard Superspeed Black model.
Battery life and charging routine
Battery life is one of the strongest reasons to consider the Amazfit GTR 4 smartwatch. Amazfit rates it for up to 14 days in a typical-use scenario, up to 7 days with heavy use, up to 24 days in Battery Saver Mode, and up to 50 days in clock mode. GPS endurance is listed at up to 25 hours in Accuracy GPS mode, 44 hours in Balanced GPS mode, and 52 hours in Power Saving GPS mode.
These figures are laboratory-style estimates, not a promise for every user. Frequent GPS workouts, phone calls, music playback, continuous health monitoring, a bright display, notifications, and always-on mode will reduce battery life. Even with those trade-offs, the GTR 4 is designed to be charged roughly every one or two weeks for typical use rather than every evening. Amazfit lists magnetic charging and an approximate two-hour charging duration.
Dual-band GPS and route navigation
The Amazfit GTR 4 smartwatch uses dual-band circularly polarized GPS technology and supports six satellite positioning systems. This design aims to improve positioning in environments with trees, tall buildings, and other sources of signal reflection. It can record outdoor movement for running, cycling, hiking, walking, and many other activities without requiring the phone to provide every location point.
Route files can be imported from the Zepp App and followed in real time on the watch. Track Run mode adds running-specific data, while Smart Trajectory Correction can help align a track workout with a selected 200- or 400-meter lane when positioning signals briefly weaken. Navigation features depend on supported activity modes and the quality of the local satellite environment, so routes should be planned with normal outdoor awareness rather than relying on the watch as a sole navigation tool.
Sports modes and strength recognition
With more than 150 sports modes, the Amazfit GTR 4 smartwatch covers a broad range of activities. The list includes running, walking, cycling, swimming, hiking, strength training, HIIT, yoga, skiing, rowing, racquet sports, ball sports, and many less common activities. The watch can automatically recognize eight sports movements and can recognize 25 strength-training exercises inside the Strength Training mode.
Strength recognition can count repetitions, track rest time, and show exercised muscle groups in the Zepp App. Interval-training templates can also be created for supported activities, with warm-up, training, rest, and warm-down stages. These features are useful for people who want structure without moving to a specialist sports watch, although athletes with highly technical training requirements may still prefer a dedicated Garmin, Polar, COROS, or Suunto model.
PeakBeats training and recovery metrics
After a workout, PeakBeats can present performance and training context such as estimated maximum oxygen uptake, recovery time, training load, and training effect. The purpose is to help users understand how difficult recent activity has been and how long recovery may take. These estimates are best interpreted as personal trends because they can change with sensor fit, workout type, terrain, weather, fatigue, and other conditions.
The GTR 4 can also broadcast live sports data such as heart rate, hydration reminders, distance, and workout status through the speaker or connected headphones in supported languages. Data can be synchronized with services such as Strava, adidas Running, Komoot, and Relive where available in the user’s region.
Heart rate, SpO2, stress, and sleep
The BioTracker 4.0 PPG sensor supports 24-hour heart-rate, blood-oxygen saturation, and stress monitoring. The watch can perform a one-tap measurement of heart rate, SpO2, stress, and breathing rate, while reminders can be enabled for unusually high or low heart rate, low blood oxygen, high stress, and breathing exercises.
Sleep tools include sleep duration, light, deep, and REM stages, daytime naps, sleep breathing quality, sleep score, and a customizable sleep schedule. Sleep Mode can reduce display brightness and mute some notifications. Morning updates can summarize weather, health information, calendar events, and other selected details, giving the watch a practical role before a workout begins.
Wellness note: The Amazfit GTR 4 smartwatch is not a medical device. Heart rate, blood oxygen, stress, sleep, breathing, VO2 Max, recovery, and training metrics are estimates intended for general wellness and fitness context, not for diagnosing or treating a medical condition. If you have symptoms or a health concern, speak with a qualified healthcare professional.
Bluetooth calls, music, and Alexa
The Amazfit GTR 4 smartwatch includes a microphone and speaker for Bluetooth phone calls when paired with a compatible phone. It can show call and app notifications, control phone music, and store music on the watch for direct playback. Amazfit lists up to approximately 2.3GB of usable music storage, although actual space depends on system requirements and software.
Amazon Alexa is built in for supported functions such as timers, questions, translations, and smart-home commands. The watch also offers an offline voice assistant for selected watch actions without an internet connection. Alexa, music playback, calls, and third-party integrations require compatible phone, app, account, language, and regional support, so check the Zepp App settings before relying on any individual feature.
Water resistance and everyday durability
The Amazfit GTR 4 smartwatch is rated 5 ATM, which corresponds to water pressure equivalent to a depth of 50 meters under the relevant testing standard. Amazfit describes the watch as suitable for splashes, snow, showering, and swimming within its guidance. The company also advises removing the watch for hot showers or saunas because excessive steam can affect seals over time.
Use a fluoroelastomer or other suitable strap for swimming and follow the manufacturer’s instructions for cleaning and drying. Water resistance can decline after impacts, repairs, disassembly, or ordinary wear. GPS and sensor performance can also vary in water, indoors, or in difficult environments, so training data should be treated as an estimate rather than a guaranteed measurement.
Compatibility and Zepp App experience
The Amazfit GTR 4 smartwatch supports Android 7.0 and above and iOS 12.0 and above through the Zepp App. The app manages pairing, watch faces, route files, workouts, health trends, notifications, firmware updates, music, and integrations. Apple Health and Google Fit support help the watch fit into broader health-data ecosystems, while phone-call and notification features depend on the paired phone.
Zepp OS 2.0 provides a low-power interface with mini apps, games, shortcut cards, store membership cards, alarms, weather, timers, to-do lists, and find-my-phone tools. This is a practical middle ground between a basic fitness band and a full Wear OS or watchOS device. Buyers should not expect the same third-party app ecosystem or cellular independence as an Apple Watch or premium Android smartwatch.
Amazfit GTR 4 smartwatch buying considerations
The GTR 4 is a good fit for buyers who want a large round display, long battery life, extensive sports tracking, dual-band GPS, music storage, Alexa, and a classic watch design at a value-oriented price. It is especially appealing to people who dislike daily charging but still want calls, notifications, workouts, and health summaries from the wrist.
It may be less suitable for users who require FDA-cleared medical features, LTE independence, deep third-party apps, or the most advanced training analytics. The standard Amazon listing can also be unavailable, so compare current stock, color, seller, warranty, and official Amazfit availability. Do not confuse the standard GTR 4 with the GTR 4 Limited Edition, GTR 4 New, GTR 4 Pro, or later Amazfit models.

Is the Amazfit GTR 4 smartwatch worth considering?
The Amazfit GTR 4 smartwatch is worth considering if you want dual-band GPS, route import, 150-plus sports modes, strength recognition, sleep and stress tools, Bluetooth calls, music storage, Alexa, and up to 14 days of typical-use battery life in a classic 46mm case. Its large AMOLED screen and physical crown make it easy to operate, while Zepp OS keeps the experience relatively efficient.
It is less suitable for shoppers seeking a modern in-stock Amazon listing at all times, advanced clinical health functions, LTE calls without a phone, or a large premium app ecosystem. Availability and pricing may change, so verify the live buying options before planning around the GTR 4.
Final verdict
The Amazfit GTR 4 smartwatch delivers an unusually broad feature set for a value-focused sports watch. Dual-band GPS, route navigation, 150-plus sports modes, PeakBeats training context, 24-hour health monitoring, sleep tools, Bluetooth calls, music storage, Alexa, and long battery life make it a flexible companion for everyday fitness. The main cautions are the age and availability of the Amazon listing, the limits of wellness measurements, and the fact that Zepp OS is not as expansive as watchOS or Wear OS. If you can confirm stock and want a large classic-style watch that charges less often, the Superspeed Black GTR 4 remains worth comparing.
