Firstly, the Xiaomi Watch S4 dazzles with an elegant and premium design, boasting a frame made of aluminum alloy and an exquisite finish with PVD technology.

This advanced coating process provides a refined texture and high-gloss details combined with a matte finish.

Its trimmed corner design not only enhances the aesthetics but also makes the watch appear thinner and narrower.

On the other hand, the quick-installation interchangeable bezel 2.0 provides multiple optimizations in the structure and materials compared to its predecessor, the Xiaomi Watch S3.

But in addition to adding versatility to the design, the Xiaomi Watch S4 smartwatch allows you to activate exclusive watch faces with specific functions, adapting to your preferences with a touch of unique personalization.

Rotating crown for easy navigation and quick access to Widgets.

And that´s not all: the Xiaomi S4 smartwatch incorporates a rotating crown, which facilitates both navigation through the screen and quick access to your favorite Widgets.

When combined with the advanced HyperOS 2.0 system, the interaction is even more fluid and the operations are faster, thus optimizing your daily user experience.

1.43-inch AMOLED screen with a maximum brightness of 2200 nits.

If we look at the front of the Xiaomi Watch S4, we can inspect the splendid next-generation 1.43-inch AMOLED screen.

This offers a maximum brightness of 2200 nits, thus guaranteeing exceptional visibility even outdoors.

Dual microphone with noise reduction for clear calls.

To all this we must add a noise reduction system with a double microphone, which significantly improves the quality of Bluetooth calls compared to the previous model, making them clearer and sharper even in noisy environments.

Advanced physical condition and wellness control.

To continue, this Xiaomi smartwatch includes advanced health care functions, such as its own algorithm that improves the accuracy in monitoring heart rate.

In addition, it incorporates a physical exam with just one click, and also detects sleep rhythm disorders and offers respiratory training courses.

Advanced professional sports mode.

Finally, the Xiaomi Watch S4 is designed for demanding athletes, as it has a posture recognition function when running, thus supporting a more detailed and effective analysis of your workouts.
