The Amazfit GTS 4 watch body is also made of aerospace-grade aluminum alloy and given a frosted finish, but it looks and feels better all around (especially for girls).

The watch body, which doesn’t include the strap, weighs about 28.1 g, and the strap weighs about 47.3 g. When compared to the GTR 4, it is much lighter and more comfortable to wear.

Even though the watch body of GTS 4 is smaller and lighter than that of GTR 4 because of its 1.73-inch square screen, it is not less rich in content display than GTR 4, and the content display in the corner of GTS 4 is better.

There is no clear difference between the GTS 4 and the GTR 4 in terms of the system, monitoring your health, helping you with sports, etc.

The screen-to-body ratio of the Amazfit GTR 4 dial is very high, so a lot of information can be shown on one screen. Something else that’s interesting is. The outer circle and the inner circle of this screen work in very different ways. The bright surface technology is used on the inner circle, which makes it look very light and clear. On the first smart watch with AG on the screen cover, two different polishing processes are combined to create a “glossy and matte” look that stands out.

The body of the watch is made of an aerospace-grade aluminum alloy that has been treated with a frosting that gives it a soft feel and makes it hard to get fingerprints on it.

On the Amazfit GTR 4, there are two physical buttons, one black on the outside and one red on the inside, which makes them very noticeable.

The Amazfit GTR 4 has two physical buttons one black and one red.

The top button is the traditional digital crown of the Amazfit Watch. You can press it or turn it. It feels very smooth to turn. You can slide to use the watch app on the Zepp OS 2.0 system. It is sensitive to touch and easy to use. The motor’s vibration feedback effect makes the experience pretty cool.

The other button lets you customize the setting function. As shown in the image below, you can set the arrival function in “Settings-Preferences” (nearly 40 functions are optional), which is also very useful. For example, the system’s default “sports” function lets you quickly enter the sports interface with one tap.

Zepp OS 2.0

Zepp OS 2.0 gives the Amazfit GTS 4 and GTR 4 a more powerful experience. During my own use, it worked just as smoothly and was just as light as the last generation.

Zepp OS 2.0 completely changes the negative one-screen smart card, allows important information to be put on top, and lets you customize cards and sorting so you can look at information quickly.

Zepp OS 2.0 lets you swipe the dial screen left or right to use the other five secondary screen display interfaces. These are sports, heart rate, weather, PAI, and music playback.
