The Amazfit T-Rex 3 is a rugged GPS smartwatch built for hiking, trail running, cycling and demanding outdoor training. Its 1.5-inch AMOLED screen reaches up to 2,000 nits of peak brightness, with a 480 × 480 resolution that keeps maps and workout data easy to read in bright conditions. A stainless-steel bezel, four physical buttons and a responsive glove mode make the watch practical when the weather changes or touchscreen operation is less convenient.

Dual-band satellite positioning supports six GNSS systems, while downloadable offline maps, imported routes and turn-by-turn directions help with navigation on unfamiliar trails. The watch offers 177 sports modes, structured workout options and compatible external workout-device connections. Heart-rate, blood-oxygen, sleep and recovery tracking feed the Zepp app and training insights. Its 10 ATM water-resistance rating and manufacturer diving certification support selected water activities, including freediving within the stated 45 m limit; always follow the model-specific water-use guidance.

The 700 mAh battery lasts up to 27 days with typical use or up to 42 hours in accurate GPS mode. The headline 180-hour GPS figure is only available in restricted maximum-battery settings for supported outdoor modes, with reduced features and tracking settings. Bluetooth 5.2 and 2.4 GHz Wi-Fi handle device connection and downloads. Charging takes approximately three hours using the supplied magnetic base and a separately provided USB-C cable. This is the original T-Rex 3, not the T-Rex 3 Pro.

Suggested Use & Compatibility

Choose T-Rex 3 for trail running, hill walking, hiking, open-water training and longer outdoor sessions where offline maps and physical controls are valuable. Download the required maps through the Zepp app before setting out, check your route and carry suitable independent navigation for remote terrain. Compatible Bluetooth heart-rate straps and cycling/running sensors can extend workout recording. The 180-hour GPS maximum is a restricted power-saving mode, not continuous high-accuracy GPS use.

Pair with a compatible Android 7.0+ or iOS 14.0+ phone using Bluetooth 5.2 and the Zepp app. A magnetic charging base is supplied, but you will need your own suitable USB-C cable. Water use is subject to the 10 ATM rating and the manufacturer’s 45 m freediving certification; neither means unlimited diving depth or immunity to impact. Remove the watch for saunas or hot showers, and check low-temperature restrictions before mountain use. Fitness and health indicators are not clinical measurements.
