Product details
The Xiaomi Watch S1 brings a classic round watch design together with fitness tracking and connected functions. Its stainless steel case and sapphire glass protect a 1.43-inch AMOLED display, while a choice of watch faces lets you adapt the appearance to your day. The Black version pairs its dark case with black straps; the Silver version combines a silver case with brown leather and grey fluororubber straps. Each colour includes a leather strap and a fluororubber strap, giving you a practical choice between different activities.
Use the watch to record supported workouts and keep everyday activity information close at hand. Xiaomi lists 117 workout modes, including 19 professional modes, with the available selection depending on the software version. Built-in dual-band positioning supports GPS, BeiDou, GLONASS, Galileo and QZSS for outdoor activities. A dedicated sport button provides quick access to a favourite workout, and supported automatic detection can recognise walking, outdoor running and treadmill exercise. The display has a 466 × 466 resolution, helping present workout details and notifications clearly.
Heart-rate, blood-oxygen and sleep features provide information for personal wellbeing. These functions are for reference rather than medical diagnosis or treatment. Some monitoring options and alerts need to be enabled in the companion app. Bluetooth calling uses a connected compatible phone, and the watch includes a microphone and speaker. Bluetooth 5.2 and 2.4GHz Wi-Fi are listed in Xiaomi’s specifications. The manufacturer lists compatibility with Android 6.0 or iOS 10.0 and above; check the current Mi Fitness app requirements for the phone you plan to use.
A 470mAh lithium-ion polymer battery supports up to 12 days in Xiaomi’s typical-use test or up to 24 days in power-saving mode. Actual use varies with settings and activity. Charging uses the included wireless dock. The case measures 46.5 × 46.5 × 11mm, excluding the strap and local protrusions. Its 5 ATM rating covers appropriate shallow-water activities, using the fluororubber strap; avoid hot showers, saunas and diving. The package includes the watch, wireless charging dock, USB cable, manual and additional fluororubber strap.
