Xiaomi Watch S3

The Xiaomi Watch S3 (2024) is a full-featured circular smartwatch that stands apart with a system of interchangeable aluminum bezels available in multiple colors, allowing hardware-level visual customization without replacing the watch. Running Xiaomi HyperOS, it launched globally at approximately $124, making it one of the most capable budget smartwatches available from a major brand. The 1.43-inch AMOLED display runs at 60Hz with 600 nits peak brightness for outdoor legibility. Dual-band L1/L5 GPS across five satellite systems (GPS, GLONASS, BeiDou, Galileo, QZSS) provides positioning accuracy typically reserved for watches costing two to three times more. Health sensors include optical heart rate, SpO2, and stress monitoring. Over 150 sport modes cover everything from gym workouts to open-water swimming. Alexa voice assistant is integrated, and NFC enables Xiaomi Pay for contactless transactions. Battery life reaches 15 days in typical use, with Xiaomi's rapid charging delivering two days of power from a 5-minute charge. At 44g the watch is comfortable for all-day wear. Xiaomi does not have official US distribution, so units on Amazon arrive via grey import channels, which can complicate warranty claims. The app ecosystem is thinner than Garmin Connect or Samsung Health, with limited third-party fitness platform integrations. For budget-conscious buyers who want dual-band GPS and genuinely long battery life at a fraction of Garmin or Apple pricing, the Watch S3 offers exceptional value.
