The T-Rex 2 exhibits a rugged military aesthetic, reminiscent of its predecessor, with visible screw heads and a protective bar featuring Amazfit lettering on the right side.

Available in four colors – all black, black with gold elements, green, and beige – the T-Rex 2 offers users diverse style options.

Constructed with matte plastic and a metal edge around the display, the T-Rex 2 emphasizes durability.

The 1.39-inch display is protected by glass, and the watch proudly claims to meet military standards in 15 disciplines.

This includes resistance to extreme temperatures ranging from -40 to 70 degrees Celsius, 240 hours in a wet environment, and 90 hours in saltwater.

With a waterproof rating of up to 10 ATM, it’s ready for aquatic adventures.

The watch boasts four control buttons, two on each side of the display, providing easy navigation even when wearing gloves.

A small speaker is placed under the protective bar, though limited to beeps without media playback capability.

The measuring sensors and charging contacts are located on the underside, and the 22mm-wide silicone strap adds to the overall durability.

The always-on display feature, with customizable settings, adds to the user experience.

Despite a minor drawback of a tactile edge between the display and frame, causing slight distortion at the edges, the display impresses with its readability and responsiveness.

Notably, the T-Rex 2 uses PMW with a low frequency of 55.53 Hz to control the panel.
