The Xiaomi Watch S3 is a stylish mid-range smartwatch launched in October 2023 (global rollout in early 2024). It stands out with its unique interchangeable bezel system for easy customization, premium build, and excellent battery life, running on Xiaomi’s HyperOS. It’s a great option for fitness tracking, notifications, and Bluetooth calls without needing a full Wear OS experience.
