Amazfit GTS 4 Autumn Brown Smartwatch – 1.75-Inch AMOLED Display

Product Description

The Amazfit GTS 4 Autumn Brown combines precise fitness tracking with a slim rectangular design that suits workouts, office wear and everyday use. This specific color variant features a warm Autumn Brown finish with a lightweight 20mm woven nylon strap, giving the watch a softer, more breathable feel than traditional silicone bands.

Its ultra-large 1.75-inch HD AMOLED display offers a 390 × 450 resolution, 341 PPI pixel density and a 72.8% screen-to-body ratio. The wide screen provides more space for viewing workout statistics, incoming calls, messages, health readings and navigation instructions. Always-On Display support and more than 150 watch faces allow the screen to be customized for fitness, casual or professional use.

The slim aluminum-alloy frame measures approximately 9.9mm thick, while the watch body weighs about 27g without the strap. A gemstone-style navigation crown provides precise control when scrolling through applications, menus and health information.

Autumn Brown Design with Nylon Strap

The Autumn Brown version is visually different from the standard black, white and pink GTS 4 models. Its warm brown finish and matching woven nylon strap give the smartwatch a more natural, fashion-focused appearance without removing its sports functionality.

The nylon band is lightweight and breathable, making it suitable for extended daily wear and sleep tracking. Its adjustable design allows the fit to be changed more precisely than a strap with fixed buckle holes. The watch uses a standard 20mm strap width, so the original band can be replaced with other compatible 20mm straps when a different look or material is preferred.

Large AMOLED Display

The Amazfit GTS 4 display is designed to show more information without making the watch feel bulky. Its 1.75-inch rectangular AMOLED panel offers clear colors, deep contrast and sharp text for workout summaries, health measurements and smartphone notifications.

More than 150 downloadable watch faces are available, including styles with matching Always-On Display layouts. Users can select information-focused faces for training or simpler designs for work and formal settings.

Accurate Dual-Band GPS

The GTS 4 uses a dual-band circularly polarized GPS antenna and supports six satellite positioning systems. This setup helps improve location tracking around tall buildings, trees and other environments that can interfere with standard single-band GPS.

Routes can be imported from the Zepp App and followed on the watch during running, walking, hiking or cycling activities. Track Run Mode and smart trajectory correction further support users who want clearer distance, pace and route information.

More Than 150 Sports Modes

The Amazfit GTS 4 supports over 150 workout modes, including running, walking, cycling, swimming, strength training, yoga and indoor exercise.

Its strength-training mode can automatically identify dozens of exercise movements, count repetitions and record rest time between sets. After training, the Zepp App can display which muscle groups were exercised and how long they were active.

Eight common activities can also be detected automatically, reducing the need to manually start every workout. The PeakBeats algorithm provides performance information such as VO₂ Max, training load, recovery time and training effect after supported exercises.

Health and Sleep Monitoring

The BioTracker 4.0 PPG biometric sensor supports continuous heart-rate, blood-oxygen saturation and stress monitoring. The watch can also measure heart rate, SpO₂, stress and breathing rate together through its one-tap measurement feature.

Health alerts can notify the wearer when supported readings appear unusually high or low. Sleep tracking records light, deep and REM sleep stages, daytime naps and sleep-breathing information. Custom sleep schedules are useful for people who sleep during the daytime or work irregular shifts.

These functions are intended for general fitness and wellness monitoring and should not be used as medical diagnoses.

Bluetooth Calls, Alexa and Music

A built-in microphone and speaker allow users to answer Bluetooth phone calls directly from the watch when it is connected to a compatible smartphone. The GTS 4 does not have independent cellular connectivity, so the paired phone must remain within Bluetooth range.

Amazon Alexa can be used for supported online voice requests, while the offline voice assistant can control selected watch functions without an internet connection.

Music files can also be stored on the watch for independent playback through the speaker or compatible Bluetooth headphones. Users can alternatively control music playing on their smartphone.

Battery Life

The 300mAh battery provides up to eight days of typical use or approximately four days under heavy-use conditions. Battery Saver Mode can extend operation further by limiting selected functions.

In high-accuracy GPS mode, the watch is rated for up to 16 hours of continuous tracking. Actual battery life varies according to Always-On Display use, screen brightness, Bluetooth calls, music playback, health-monitoring frequency and GPS activity.

Water Resistance

The Amazfit GTS 4 carries a 5ATM water-resistance rating, allowing it to handle rain, sweat and supported swimming activities. It should not be used for scuba diving, high-speed watersports, hot showers or sauna use.

The Autumn Brown nylon strap may take longer to dry than a silicone band after swimming or intensive workouts.
