1.43-Inch AMOLED HD Display

The Haylou Watch 4S features a circular 1.43-inch AMOLED display that produces rich colours, sharp text and clear fitness data. Its 466 × 466 resolution makes notifications, workout statistics and watch faces easy to read.

With brightness reaching up to 1000 nits, the display remains visible in bright outdoor environments. The 2.5D high-hardness curved glass provides smooth touch control while complementing the watch’s premium round design.

The always-on display option also lets you check the time and selected information without repeatedly waking the screen.

Independent Five-System GPS Tracking

One of the most important advantages of the Haylou Watch 4S is its built-in positioning system. The watch supports five major satellite networks:

• GPS

• BeiDou

• GLONASS

• Galileo

• QZSS

Independent GPS allows the watch to record outdoor routes, distance and movement data without depending entirely on the phone’s positioning system.

This makes it especially useful for outdoor running, walking, hiking and cycling. The GPS sports mode can operate for up to approximately 26 hours, although actual performance depends on settings, signal strength and usage conditions.

Bluetooth Calling from Your Wrist

Bluetooth 5.3 connectivity allows you to make and receive calls directly through the watch when it is connected to a compatible smartphone.

The Haylou Watch 4S provides:

• One-touch call answering

• Direct calling from the watch

• Call history access

• Frequently used contact access

• Emergency calling after setup

• Message and application notifications

This feature is useful while driving, exercising, working or whenever taking out your phone is inconvenient.

The watch displays notifications from supported calling, messaging and social applications. Message replies and available notification functions may vary between Android and iOS devices.

More Than 120 Sports Modes

Track different types of indoor and outdoor activities with more than 120 sports modes. The Watch 4S can record useful workout information such as:

• Heart rate

• Workout duration

• Calories burned

• Steps

• Distance

• Pace

• GPS route

Its combination of activity sensors and independent positioning makes it suitable for users who want more detailed outdoor workout records than a basic fitness band can provide.

Workout records can be reviewed through the Haylou Fun mobile application.

Everyday Health and Wellness Monitoring

The Haylou Watch 4S includes multiple wellness-monitoring tools that help users understand daily activity patterns and long-term trends.

Heart-Rate Monitoring

Monitor heart rate throughout the day and during supported workouts. Heart-rate alerts can notify you when unusual readings are detected according to the configured settings.

Long-Lasting 400mAh Battery

The Haylou Watch 4S uses a power-efficient chipset with a 400mAh battery to reduce the need for frequent charging.

Estimated battery performance includes:

• Up to 10 days in everyday-use mode

• Up to 26 hours in continuous GPS sports mode

Battery life will vary according to display brightness, always-on display use, Bluetooth calling, GPS activity, health-monitoring frequency and notification settings.
