Amazfit officially launches new compact T-Rex 3 Pro smartwatch

Amazfit has officially announced the launch of the T-Rex 3 Pro 44 mm smartwatch. This watch has been available to purchase since the end of October 2025, joining the two older 48 mm versions of the wearable.

Since then, the Amazfit T-Rex 3 Pro 44 mm smartwatch has become available through the brand’s Amazon storefront in the US. Both the Arctic Gold and Black Gold versions of the watch are selling for $399.99 each. Similarly, at Amazon in European countries like the UK, France and Germany, the Black Gold version of the 44 mm wearable can now be purchased for £399.90/€399.90. Plus, Amazfit recently announced that the Arctic Gold version of the Amazfit T-Rex 3 Pro 44 mm smartwatch would be released across Europe in mid-November.

The 44 mm version of the T-Rex 3 Pro has a smaller 1.32-inch AMOLED display and a lower battery capacity of 640 mAh, said to power the watch for up to 17 days on a single charge. Otherwise, the two sizes offer identical functionality. You can use the smartwatch to log exercise in over 180 modes, with six satellite system positioning to track your route or provide directions. Hardware upgrades compared to the standard T-Rex 3 include integrated microphone and speakers for functions like Bluetooth calling, and a built-in flashlight offering two colors. Other features include offline maps, route planning, heart rate monitoring, and support for diving with 10 ATM waterproofing.
