2.1 Display & Rugged Body Structure

Wide-Angle IPS Display

The VO531 equips a 2.01-inch square HD IPS full-touch screen with a 178° ultra-wide viewing angle. It optimizes outdoor sunlight visibility and low-light display clarity, ensuring stable data reading from multiple viewing angles. Users can customize and upload exclusive watch faces via the matched wellness APP for personalized display configuration.

Scratch-Resistant Alloy Body

It adopts high-hardness scratch-resistant alloy housing with rugged structural design. The sturdy body effectively resists daily friction, collision and extrusion damage, adapting to high-intensity outdoor and construction site usage. Independent physical side buttons support precise operation, accessible even with gloves.

Exclusive Side LED Flashlight

A built-in side LED flashlight serves as the core exclusive functional hardware. It provides stable high-brightness auxiliary lighting for night hiking, camping, field patrol, dark corridor walking and night shift work, replacing handheld lighting tools and improving outdoor activity convenience.

Wearable Strap Configuration

The device comes with a durable sweat-proof silicone strap. The flexible and skin-friendly material adapts to long-term daily wear and high-intensity sports scenarios, featuring wear resistance and easy cleaning without frequent replacement.

2.2 Connectivity & System Compatibility

Stable Bluetooth 5.0 Linkage

Equipped with a low-power Bluetooth 5.0 chip, it achieves stable, low-delay wireless connection with smartphones. It supports two-way Bluetooth calling, real-time message synchronization and data transmission, ensuring smooth daily intelligent linkage and interactive experience.

Positioning Function Note

This watch does not integrate an independent GPS chip. All sports trajectory recording functions rely on the paired smartphone’s GPS signal, fully meeting daily fitness and light outdoor sports recording demands.

System Compatibility

It maintains full compatibility with Android 8.0 and above, as well as iOS 12.0 and above mainstream mobile systems, covering nearly all smart devices in the global consumer market.

2.3 Battery & Charging Verified Performance

Standard Charging Mode

It adopts universal magnetic pogo-pin contact charging design with automatic suction and precise positioning. The sealed charging interface isolates external dust, sweat and oil stains to protect internal circuits and extend service life. It universally adapts to standard 5V/1A USB power sources including wall chargers and power banks. A full charging cycle takes approximately 2 hours under standard laboratory conditions.

Graded Ultra-Long Endurance

Built-in 320mAh high-safety lithium polymer battery with multi-layer overcharge and short-circuit protection. Standard lab test data delivers clear graded endurance performance: 5 to 7 days of stable usage under daily mixed mode; up to 35 days of ultra-long standby under power-saving monitoring mode for long-term unattended wear.

2.4 IP68 Dustproof & Waterproof Specifications and Usage Limits

Compliant with ISO 22810 industry standard, the VO531 reaches professional IP68 dustproof and waterproof grade, improving environmental adaptability for outdoor and daily scenarios.

Supported Usage Scenarios

It completely resists daily dust deposition, skin sweat erosion, wind and sand invasion, and accidental light rain splashes. It supports daily commuting, gym fitness, outdoor hiking, camping and field work scenarios.

Unsupported Usage Scenarios

The device does not support long-term underwater submersion, swimming, diving, high-pressure water flushing, hot water bathing or sauna steam environments. Hardware damage caused by improper usage will void the official warranty.

Performance Attenuation Note

Internal waterproof and dustproof rubber gaskets experience natural aging after long-term wear and environmental erosion. Protective performance gradually weakens over time, which belongs to normal physical wear and tear.
