The case made of premium stainless steel and an advanced set of technologies are designed for more demanding users who need a reliable device for everyday business, accurate sports analytics and long-lasting operation without frequent charging. Uncompromising round AMOLED screen The watch boasts a 1.48-inch round-shaped AMOLED screen with a high resolution of 480 x 480 pixels. It stands out with its exceptional brightness, which reaches a peak of up to 2500 nits, which means that all data, notifications and graphs are perfectly readable even under direct bright sunlight. Built-in protection against accidental touches due to water droplets ensures trouble-free use in all weather conditions. Advanced sensors and professional exercise monitoring A renovated system of four light channels and photodiodes is built in, which provides up to 98.4% accuracy in heart rate measurement. The watch offers comprehensive stress analysis, an advanced sleep phase monitoring algorithm, and continuous blood oxygen saturation measurement ($SpO_2$). With more than 150 sports modes, including an advanced cycling mode and support for external Bluetooth power meters, it becomes an indispensable accessory for every athlete. Accurate outdoor route tracking is enabled by an upgraded dual-band five-system GNSS receiver. Exceptional battery life and HyperOS 3 Thanks to the energy-efficient Xiaomi HyperOS 3 operating system and a powerful 815 mAh battery, the watch achieves above-average autonomy, which with moderate use is up to 21 days on a single charge. The device supports receiving all notifications from your smartphone and making calls directly from your wrist via the built-in speaker and microphone. Durability and prestigious design The 46 mm case is made of durable 316L stainless steel and is complemented by a comfortable black fluoro-rubber strap, suitable for both sports adventures and formal meetings. With a water resistance rating of 5 ATM, the watch is safe from splashes, showers and swimming in the pool or shallow water.

It is important to know

The Xiaomi Watch S5 46mm smartwatch is designed for users looking for a universal smartwatch to monitor daily activities, health and notifications, with an emphasis on long battery life. Users who use specific applications or expect more advanced sports or medical analytics should be especially careful before purchasing.

• Phone compatibility is not always exactly the same for iOS and Android - check to see if all features are supported on your operating system.
• Due to the larger case, the watch may not be the most comfortable for users with very narrow wrists or for wearing while sleeping.
• Battery life is very good for everyday use and longer trips, but with intensive use of GPS and smart features, the operating time may be reduced.
• For heavy fitness tracking, limited advanced metrics may mean the watch is more suitable for recreational users than professional athletes.
