The HAYLOU Watch 4S is a stylish GPS smartwatch designed for everyday fitness, health tracking, and smart connectivity. Featuring a 1.43-inch AMOLED display, built-in GPS, 120+ sports modes, Bluetooth calling, and up to 12 days of battery life, it offers an attractive balance of features and affordability for Android and iPhone users.

Whether you're tracking workouts, monitoring daily wellness, or staying connected on the go, the Watch 4S provides plenty of functionality in a lightweight design.

Key Features

🖥️ 1.43-Inch AMOLED Display

The HAYLOU Watch 4S features a 1.43-inch AMOLED touchscreen with a 466 × 466 resolution, producing vibrant colors, deep blacks, and excellent readability both indoors and outdoors.

Additional personalization features include:

  • 150+ online watch faces

  • Custom watch face support

  • Two interchangeable watch straps included

This allows users to customize the watch for workouts, business settings, or casual wear.

🛰️ Built-in GPS

Unlike fitness trackers that rely on a connected phone, the Watch 4S includes independent GPS, allowing you to accurately record:

  • Running routes

  • Cycling sessions

  • Hiking trails

  • Walking distance

  • Outdoor workouts

This makes it convenient for users who prefer leaving their phone behind during exercise.

🏃 120+ Sports Modes

The smartwatch supports over 120 workout modes, including:

  • Running

  • Walking

  • Cycling

  • Hiking

  • Yoga

  • Strength training

  • Indoor fitness

  • Outdoor sports

It also supports Strava synchronization, making it easier to review workout data and share activities.

❤️ Health & Wellness Tracking

The Watch 4S offers a range of daily wellness features, including:

  • Sleep monitoring

  • Stress tracking

  • Women's health tracking

  • Daily activity tracking

These tools help users better understand their lifestyle habits and overall wellness. They are intended for fitness and wellness purposes and are not medical devices.

📞 Bluetooth Calling & Notifications

With Bluetooth 5.3, users can:

  • Make and receive calls

  • View incoming call alerts

  • Receive app notifications

  • Read message notifications

  • Send quick replies on supported Android devices

These smart features help you stay connected without constantly checking your phone.

🔋 Long Battery Life

Powered by a 400mAh battery, the Watch 4S offers:

  • Up to 12 days of typical use

  • Up to 17 days of standby time

Actual battery life depends on GPS usage, screen brightness, notification frequency, and health monitoring settings.

💧 1ATM Water Resistance

The 1ATM water resistance rating provides protection against:

  • Hand washing

  • Rain

  • Sweat

  • Everyday splashes

However, it is not recommended for swimming, diving, or high-pressure water activities, as 1ATM offers less protection than higher-rated watches (such as 5ATM).

Their open-ear design sits outside the ear canal, while the adjustable earhooks help keep the earbuds secure during running, workouts, commuting, and everyday activities.
