Meet Xiaomi Watch S3
At the launch of the Xiaomi 14 Series, Xiaomi surprised tech enthusiasts with the introduction of the Xiaomi Watch S3, a smartwatch set to redefine the world of wearables. What makes this timepiece stand out is its integration with HyperOS, the same system found in Xiaomi’s smartphones, creating a seamless and powerful interconnection experience.
The Xiaomi Watch S3 comes in two versions: Bluetooth and eSIM, catering to different user preferences. The Bluetooth version is priced at 799 yuan, while the eSIM version is available for 999 yuan, making it an appealing option for those looking for both functionality and affordability.
In terms of design, Xiaomi has embraced innovation. The watch features an aluminum alloy body, which not only makes it lightweight but also comfortable for extended wear. The multi-ring design on the back cover ensures a more integrated and ergonomic feel, particularly when it comes to the heart rate sensor placement.
One of the standout features of the Xiaomi Watch S3 is its “variable bezel” design. This innovative approach allows users to change the color and style of the bezel, creating a watch that can effortlessly adapt to various styles and occasions. Xiaomi offers a range of bezels, including standard stainless steel, monochrome ceramic, two-color ceramic, and cloud-forged carbon fiber options.
Each bezel variation is accompanied by a selection of dials, offering hundreds of design possibilities. From traditional dials to dynamic, component, and album dials, users have the freedom to personalize their watch faces.
The 1.43-inch OLED screen with a resolution of 466 × 466p and a high pixel density of 326, coupled with a global brightness of 600 nits, ensures excellent visibility even in varying lighting conditions. Auto-brightness further enhances the viewing experience.
Connectivity is a strong suit of the Xiaomi Watch S3. It supports NFC smart card packages, enabling users to add metro cards and access cards, and offers automatic switching of the default card at preset times. Additionally, the watch provides timely information at your fingertips, with features like takeout, taxi, and navigation status displayed when you raise your wrist.
When it comes to positioning accuracy, the Xiaomi Watch S3 boasts GNSS five-star positioning, utilizing BeiDou, GPS, GLONASS, Galileo, and QZSS for precise location tracking.
Health and fitness enthusiasts will appreciate the upgraded “12-channel sensor” for enhanced heart rate accuracy, reaching an impressive 97.95%. The watch supports over 150 sports modes and even includes a feature for an automatic call for help in case of an accidental fall.
The Xiaomi Watch S3 is built to last, with an impressive battery life. It supports 15 days of usage on a single charge, and even in Always-On Display (AOD) mode, it can last for 5 days. The eSIM typical use mode extends the battery life to 7 days, and in heavy use mode, you’ll get a solid 3 days of usage. Quick charging ensures you’re never left waiting, as just 5 minutes of charging can power the watch for two full days.

With 5ATM waterproofing, skiing professional mode, and a host of other features, the Xiaomi Watch S3 is a versatile and stylish companion for modern lifestyles. This smartwatch embodies Xiaomi’s commitment to innovation and user-centric design, delivering a superior experience to tech-savvy individuals looking for a balance between fashion and functionality.
