Overall, the HAYLOU Watch 3 is particularly suitable for users who want a large AMOLED screen, Bluetooth calling, fitness tracking and extended battery life in a stylish everyday smartwatch.
1.85-Inch AMOLED Display
The HAYLOU Watch 3 features a 1.85-inch AMOLED display with a 390 × 450-pixel resolution. AMOLED technology provides vivid colors, strong contrast and clear visuals for watch faces, notifications and fitness information.
The display can reach up to 1000 nits peak brightness, helping improve visibility in bright environments. The 2.5D curved glass gives the screen a smooth appearance and complements the premium design.
The smartwatch also supports Always-On Display (AOD), allowing essential time information to remain visible without fully waking the screen.
Bluetooth 5.4 and Bluetooth Calling
The HAYLOU Watch 3 comes with Bluetooth 5.4 connectivity. It supports Bluetooth calling through the built-in microphone and speaker.
Once connected to a compatible smartphone, users can answer or reject incoming calls from the smartwatch. This is particularly convenient when the phone is not immediately accessible.
The Watch 3 is not a standalone cellular smartwatch. It does not use a SIM card or mobile network, so calling functionality depends on the connected smartphone.
150+ Sports Modes
Fitness tracking is one of the major features of the HAYLOU Watch 3.
The smartwatch supports 150+ sports modes, allowing users to track a wide range of indoor and outdoor activities. Supported activities include different forms of running, cycling, yoga, strength training and other workouts.
The collected activity information can be synchronized with the Haylou Fun application, allowing users to review their fitness progress.
Health and Activity Monitoring
The HAYLOU Watch 3 provides several health and daily activity tracking features. Depending on the feature and software configuration, users can monitor:
-

200+ Online Watch Faces

This makes the Watch 3 suitable for both casual and formal occasions.
Premium Zinc Alloy Design
The HAYLOU Watch 3 uses a high-polish zinc alloy frame combined with a hypoallergenic silicone strap. The combination gives the smartwatch a premium appearance while keeping it relatively lightweight.
The watch measures approximately 49.3 × 37.8 × 10.5mm and weighs around 32 grams without the strap.
The hypoallergenic strap is designed for comfortable extended wear during work, exercise and everyday activities.

1ATM Water Resistance
The HAYLOU Watch 3 has a 1ATM water-resistance rating. It is designed to handle everyday exposure such as sweat, light rain and splashes.
However, 1ATM water resistance does not mean the smartwatch is suitable for swimming, showering, diving or high-pressure water activities. Users should avoid prolonged water exposure.
