Design, Comfort and Control

Even in direct sunlight, there is no visual impairment, and the content on the screen is clearly visible – which I am quite satisfied with. The strap is made of skin-friendly and soft silicone material, which will not cause discomfort when worn for a long time.

The smartwatch adopts a zinc alloy shell, and the metal CNC is precisely trimmed and sandblasted, and the overall texture is very stable. There is a speaker on the left side of the watch, and a microphone hole and buttons on the right side, which allow users to make voice calls with others through the watch – although the sound is not loud, there is no problem with daily calls.

The strap is made of skin-friendly and soft silicone material, which will not cause discomfort when worn for a long time. The wearing comfort of the strap is quite good, and the moisture is easy to drain, keeping the wrist dry. The watch is very firm after wearing, and it will not fall off even after high-intensity exercise. The strap is fixed by a specific buckle and the watch case, and the quick release design is convenient for users to replace the strap.

In terms of control, Haylou Solar Plus has also made it as simple as possible. Swipe down along the edge of the screen for the quick setting center, and swipe up for the information center. Swipe left and right to switch between function cards (exercise data, heart rate, blood oxygen, stress, sleep, weather).
