The Amazfit T-Rex 3 Pro Black Gold (48 mm) smartwatch is now available in the US. This second colorway joins the original Tactical Black (48 mm) wearable, which was released earlier in September 2025.

The T-Rex 3 Pro Black Gold (48 mm) retails for $399.99 at the brand’s online store and at Amazon, like its predecessor. It has a black watch face, black fiber-reinforced polymer casing and a black silicone strap. Plus, there is a gold colored grade 5 titanium octagonal bezel, and the same material is used for the buttons.

The new Amazfit T-Rex 3 Pro has an AMOLED display with up to 3,000 nits brightness. Features include offline maps with on-watch route planning, dual-band and six satellite positioning systems. Users can choose from over 180 sports modes, including new activities like Rucking, and there is also an integrated flashlight offering two colors. Plus, you can track a range of health metrics and use Bluetooth to make calls with an integrated speaker and microphone. The smartwatch is expected to run for up to 25 days with typical use or 85 hours in GPS Long Battery Life mode.

Amazfit’s T-Rex 3 Pro Black Gold (48 mm) watch is expected to be released in European countries like the UK, Spain and France, before the end of September 2025. The smaller 44 mm T-Rex 3 Pro in Black Gold and Arctic Gold are scheduled for release in the US on October 25th.
