Core Features Explained
1. Health Monitoring (Core Selling Point)
Heart Rate Monitoring: Provides continuous 24-hour heart rate tracking, with real-time visibility during exercise and post-activity data analysis.

Blood Pressure Measurement: Please note: The blood pressure measurement function in the vast majority of smartwatches on the market provides estimated values, calculated via optical sensors and algorithmic models. It cannot replace professional medical equipment (such as a sphygmomanometer). It is suitable for observing daily trends and as a reference, but should not be used as a basis for diagnosis.

Blood Oxygen Monitoring: Measures blood oxygen saturation levels, offering insights into physical fatigue, altitude sickness, or respiratory patterns during sleep.

Sleep Monitoring: Automatically tracks nightly sleep structure (deep sleep, light sleep, wakefulness), generating sleep reports to aid in improving sleep quality.

2. Bluetooth Calling
The watch connects to your mobile via Bluetooth, enabling direct answering or dialling of calls from your wrist.

Advantages: Extremely convenient during exercise, driving, or when your phone is out of reach, eliminating the need to retrieve it.

Requirements: The watch and phone must remain within the effective Bluetooth connection range.

3. Sports and Outdoor Activities
Supports multiple outdoor exercise modes, such as running, walking, cycling, and mountaineering.

Utilises built-in sensors to record exercise data, including steps, distance, and calories burned, helping you evaluate workout effectiveness.

4. Smart Alerts & Connectivity
Message Notifications: When paired with your phone, incoming calls, texts, WeChat, QQ, and other app messages are synchronised to the watch display.
Remote Selfie Control: Functions as a remote shutter for your phone's camera, ideal for group photos or selfies requiring specific angles.
Additional Features: Typically includes practical tools like music control, weather display, stopwatch, alarm, and phone-finding functionality.
