This device is designed for users who require detailed activity data without sacrificing convenience, offering over 100 sports modes, Bluetooth calling, and smart notifications. With a 300mAh battery supporting up to a week of typical use and wireless charging, it simplifies daily wear and data synchronisation with both Apple and Android smartphones.
Features and Construction

The watch's functionality is built around specific hardware and software capabilities verified in the source text. Its construction uses stated materials for durability and daily wear, while the internal specifications enable the advertised features.
Material and Build
The watch case is made from zinc alloy, a material chosen for its structural strength in housing the internal electronics. It features an IML (In-Mould Labelling) finish, which integrates the decorative surface layer during the moulding process for improved durability. The strap is silicone, a flexible and skin-friendly material suitable for prolonged wear during various activities and offering resistance to sweat and moisture.
Size and Practical Fit
The watch has a stated case diameter of 44mm, which provides a substantial wrist presence suitable for displaying information on its 1.39-inch screen. This size accommodates the full-touch interface and the physical encoder button (true screw clip) for navigation. The 360x360 pixel resolution on the circular screen ensures icons and data are displayed clearly. The combination of the 44mm case and the flexible silicone strap aims to provide a secure fit for a range of wrist sizes during movement.

Event or Professional Use
For sports and fitness, the watch supports a wide array of dedicated modes including walking, running, cycling, football, volleyball, tennis, and basketball. The companion app extends this to over 100 activities. Health monitoring during these activities includes tracking heart rate, blood oxygen saturation, blood pressure, and sleep quality, providing data on steps, distance, and calories burned. This makes it applicable for training sessions, gym workouts, and organised sports where performance data is useful.
Everyday Home Use
Beyond sports, the watch serves as a daily connectivity hub. It delivers notifications for calls, messages, and apps like WeChat, QQ, and WhatsApp. Functions like weather updates, music control, a stopwatch, a flashlight, a calculator, and a calendar add everyday utility. The integrated NFC and Alipay support allow for making contactless payments offline, useful for shopping or commuting. Features such as sedentary reminders, drinking water alerts, and an alarm clock promote general wellbeing in a home or office setting.
