Xiaomi S4 Ultra Smartwatch

The Xiaomi S4 Ultra Smartwatch is more than just a timepiece—it's a full-featured outdoor companion built for performance, style, and everyday practicality. Designed for those who stay active and connected, it combines rugged durability with a sleek, modern look.

At its core, the S4 Ultra runs on HarmonyOS with 256MB of ROM, delivering smooth navigation and fast response across every feature. The vivid AMOLED display ensures your stats, messages, and maps are always bright and easy to read—even under direct sunlight.

Stay in tune with your health thanks to real-time heart rate and body temperature monitoring, while Bluetooth 5.3 ensures stable, low-energy connectivity for calls, notifications, and music on the go. Built to withstand the elements, it’s also waterproof, so you don’t have to slow down when the weather turns.

With built-in NFC, you can make contactless payments with just a tap, and the GPS and compass keep you on track wherever your adventures take you.

Smart, tough, and ready for anything—the Xiaomi S4 Ultra is the smartwatch that does it all, without compromise.
