2. Verified Core Hardware Specifications

Buyers can verify all hardware parameters under standard lab test conditions. These clear values support B2B side‑by‑side comparison and mass‑order quality checks.

2.1 Display & Rugged Body Structure

Display Configuration

It carries a 1.96‑inch square water‑drop OLED full‑touch screen. Native resolution reads 240*282. Its optimized touch sensor responds well even with thin gloves. Users read content clearly in bright sunlight and low‑light conditions. Buyers or end‑users upload custom watch‑face images via the wellness APP.

Reinforced Rugged Body Design

Thickened shock‑resistant zinc‑alloy forms the main housing. The structure resists drops and impacts for heavy outdoor use. Buyers pick from two factory color sets: matte‑black plus orange, or black plus blue. The solid shell handles daily bumps and surface friction.

Dual Interchangeable Straps & Usage Rules

The package includes two swap‑ready straps. A tough tactical silicone strap works for sports. A genuine‑leather strap fits casual or business occasions. Leather straps hold no internal waterproof gaskets. Users must fit the silicone strap before any water contact. This rule stops short‑circuit damage inside watch hardware.

2.2 4G System & Connectivity Architecture

Full Standalone Android 4G System

This watch runs full standalone Android OS. Users insert a Nano‑SIM card for 4G full‑network access. Owners make and receive calls, send SMS, browse web pages and install compatible Android apps. The hardware works fully without a paired smartphone nearby.

Front Video Call Camera

A front‑facing 200W pixel camera sits on the shell. Users launch real‑time video calls over active 4G cellular service. The feature supports remote face‑to‑face talks for outdoor or unattended field scenarios.

Independent GPS Positioning

A standalone GPS chip sits inside the hardware. Users record outdoor tracks, measure distance and calculate elevation without a phone. It captures accurate running, cycling, hiking and cross‑country sports data.

System Compatibility

It works with Android 8.0 or newer, and iOS 12.0 or newer. This compatibility covers most mainstream consumer mobile devices sold worldwide.

2.3 Battery & Charging Standard

Charging Specifications

Magnetic pogo‑pin contacts snap into place for charging. Sealed ports block dust, skin oil and dirt to protect inner circuits. Users connect any standard 5V/1A USB power supply. A full charge completes within 2.5 hours at a stable 25‑degree‑C lab environment.

Verified Endurance Data

An 800‑mAh lithium‑polymer battery includes multi‑layer safety hardware. These modules stop over‑charge, over‑discharge and short‑circuit risk. Lab test results show clear runtime tiers. Heavy 4G‑mode work delivers 3‑5 continuous use days. Bluetooth‑only wellness mode yields 6‑7 mixed‑use days.

2.4 IP67 Dustproof & Waterproof Specifications and Usage Limits

This hardware follows ISO 22810 industry standards and reaches IP67 dust‑and‑splash‑proof grade. It handles typical daily and outdoor environmental exposure risks.

Supported Usage Scenarios

It blocks fine dust, sweat residue, wind‑blown grit and accidental light‑rain splashes. Owners wear it for outdoor exploration, fitness workouts, daily commutes and field‑site assignments.

Unsupported Usage Scenarios

Do not submerge it for long periods. Avoid swimming, diving, high‑pressure water jets, hot baths and sauna steam. The factory voids hardware warranty for damage caused by such misuse.

Performance Attenuation Note

Internal rubber sealing gaskets slowly age with heavy outdoor wear. Sweat and grit slowly lower original splash‑proof performance. Users treat this outcome as normal physical wear‑and‑tear.

3. Sensor Configuration & Health Monitoring Capabilities

Mandatory Non‑Medical Disclaimer: The WO431 generates heart‑rate, SpO2, stress and sleep output for wellness reference only. This hardware is not clinical medical equipment. Users cannot apply its readings for disease diagnosis or treatment guidance. Seek licensed medical help for ongoing physical discomfort or abnormal vital‑sign results.

Lab tests return over 97‑percent baseline heart‑rate accuracy. Real‑world results shift due to strap tightness, arm hair, wrist tattoos, skin thickness or ambient temperature.

3.1 24/7 Real-Time Vital Sign Monitoring

The watch runs automatic 24‑hour heart‑rate tracking. Buyers set custom vibration triggers for abnormal heart‑rate alerts. It takes regular SpO2 samples and calculates daily stress levels. The firmware detects sleep states and separates light‑sleep, deep‑sleep and REM phases. It outputs sleep‑quality reports and mutes alerts automatically at bedtime.

3.2 Outdoor Sports & Trajectory Tracking

Built‑in GPS pairs with many indoor and outdoor sport profiles. The watch captures tracks, duration, step count and calorie values locally. Users view data offline right on‑device. After Bluetooth reconnection, it pushes records to the wellness APP for long‑term trend review and archiving.

4. Functional Features & APP Ecosystem

4.1 4G Standalone Full Intelligent Functions

In 4G mode, the watch works fully independent of phones. Owners place or receive voice / video calls, read SMS, surf web and install third‑party apps. It also handles local media playback and basic file management for field‑work use‑cases.

4.2 Bluetooth Linkage Daily Wellness Functions

Switch to Bluetooth‑linkage mode to save battery power. Users keep two‑way Bluetooth calls, message vibration alerts and live weather sync. They also control music and trigger remote camera shutter actions.

4.3 Built-In Practical Toolset

It includes many practical outdoor‑oriented tools. Buyers access multi‑group alarms, sedentary and drinking reminders, stopwatch, countdown timer, voice assistant and phone‑finder. Pre‑loaded tactical‑style watch faces support user‑uploaded custom dial art.

4.4 Multi-Language APP Cloud Synchronization System

The matching multi‑language wellness APP syncs biometric and sport data bidirectionally. It stores sleep and GPS track history, generates weekly and monthly wellness dashboards. Users adjust function settings and enable cloud‑backup to guard against data loss.

5.4 Quality Control & After-Sales Warranty

Every finished unit passes our four‑step factory aging and calibration test suite. Test engineers validate 4G module stability, GPS accuracy and video‑call performance. Our 12‑month global hardware warranty covers factory‑origin manufacturing defects only. Strap wear, gasket aging and user‑inflicted physical damage sit outside warranty coverage.
