2.4 IP68 Dustproof & Waterproof Performance

The VO481 adopts professional IP68 dustproof and waterproof grade, far exceeding conventional 3ATM splash resistance. It completely resists daily dust erosion, handwashing splashes, sweat and short-term cold water contact.

The following behaviors cause irreversible hardware damage and void factory warranty: Long-term underwater soaking, diving, high-pressure water flushing, hot water bathing and sauna steam exposure.

Internal sealing gaskets will naturally age with long-term daily wear, gradually reducing waterproof and dustproof protective performance. Non-original straps have no protective capability.

3. Biometric Sensors & Wellness Monitoring Functions

Disclaimer: All monitored data including body temperature, heart rate, SpO2 and blood oxygen trends is consumer-level reference data only. This device is not certified medical equipment and cannot be used for clinical diagnosis, disease judgment or treatment guidance.

7. Frequently Asked Questions

Q1: Can the VO481 work normally without a smartphone?

Basic standalone functions such as time display, temperature monitoring, heart rate tracking, step counting and alarm clock work independently. Outdoor GPS route recording and full cloud data synchronization require connection with a paired mobile phone.

Q2: What water activities is the IP68 watch suitable for?

IP68 grade supports daily dust prevention, sweat resistance, hand washing and short-term cold water immersion. It is not suitable for long-time underwater soaking, diving, high-pressure water flushing, hot water bathing and sauna, which will damage the sealing structure and void the warranty.

Q3: What customized services are available for wholesale buyers?

We provide one-stop private-label customization including logo engraving, packaging upgrading, multi-sensor threshold firmware tuning and exclusive branded APP development. NDA confidentiality agreements are supported to protect exclusive brand intellectual property.

Q4: Is the body temperature data of the watch accurate?

The watch achieves ±0.1℃ high precision under laboratory conditions. It is suitable for tracking daily body temperature trend changes. Please note that it is wrist skin temperature data, not medical-grade core body temperature, for daily reference only.

VOSITONE Smart Watch General Technical Specifications

Product Dimensions & Weight

All measurements derive from VOSITONE Lab testing data. To begin with, the watch boasts an ultra-slim profile, measuring precisely 10.1mm at its thinnest point (measured from phone surface to shell, excluding sensor area). Furthermore, its lightweight construction weighs merely 28g without the strap. However, it's important to note that final product weight may vary slightly. This variation occurs primarily because of different configurations. Additionally, manufacturing processes significantly affect final measurements. Moreover, different measurement methods may yield slightly different results.

Product Visual Representation

While product images and screen contents are shown for illustrative purposes, several important considerations apply. First and foremost, actual product appearance may differ in terms of color, size, and finish. Similarly, screen displays may vary regarding backgrounds, UI elements, and images. Most importantly, all watch face designs represent original artistic creations. Consequently, full copyright belongs exclusively to VOSITONE.

Health Monitoring Features

Heart Rate Accuracy

Lab tests demonstrate exceptional performance. Specifically, accuracy exceeds 97% at 10bpm. The testing covered numerous scenarios including, but not limited to, sedentary activities like sitting and reading, as well as various exercises such as treadmill use, running, walking, and cycling. Nevertheless, actual accuracy may vary due to several factors. Primarily, individual physiological differences play a role. Additionally, usage habits and patterns affect results. Finally, environmental conditions can influence measurements.

Blood Oxygen Monitoring

SpO2 measurements effectively track oxygen saturation levels. Essentially, this measures the percentage of oxygen-carrying hemoglobin in the blood. The system provides intermittent periodic readings rather than continuous monitoring. For optimal results, users should wear the watch snugly and properly. Moreover, keeping the arm steady during measurements improves accuracy. However, multiple factors can affect readings, including low blood perfusion, arm hair, tattoos, improper positioning, and cold temperatures.

Key operational notes include:

• Users must first enable automatic detection in the app
• When oxygen levels drop below the set threshold, the watch provides vibration alerts
• However, these alerts remain disabled during sleep periods

Medical Disclaimer

This product serves exclusively for health management purposes. Importantly, it is not classified as a medical device. All provided data serves merely for reference. Specifically, the information is not intended for medical diagnosis. Therefore, it should never serve as a basis for treatment decisions. For any medical concerns, users should always consult qualified healthcare professionals.

GPS Functionality(If Applicable)

The watch offers robust positioning features. In particular, it supports detailed GPS tracking through the companion app. Laboratory tests have thoroughly validated this performance. However, real-world performance depends on several factors. Environmental conditions represent a primary consideration. Similarly, individual usage habits affect results. Finally, signal interference can impact accuracy.

Water Resistance

The watch meets specific water protection standards. Specifically, it carries a 3ATM rating (30m per ISO 22810:2010). Accordingly, it's suitable for pool and shallow water activities. However, important restrictions apply. The device is not suitable for diving or snorkeling. Users should also avoid high-pressure water exposure. Furthermore, metal and leather straps lack waterproofing.

Critical notes regarding water resistance:

• Protection degrades gradually over time
• Therefore, users should consider alternative straps for swimming
• Additionally, regular inspection of seals is recommended

Charging & Battery Performance

Charging Requirements

Laboratory testing established these specifications at 25°C with 45-80% relative humidity. The device requires a minimum 5V/1A charger. Moreover, it performs best with original charging accessories. However, actual performance may vary due to several factors. Product differences represent one consideration. Similarly, usage patterns affect charging efficiency. Finally, environmental conditions play a role.

Battery Life Estimates

The typical usage scenario includes:

• 120 minutes of Bluetooth calls weekly
• 120 minutes of music playback weekly
• Continuous heart rate monitoring
• 90 minutes of GPS workouts weekly
• Daily notifications
• 200 screen activations daily

Notably, standalone GPS mode operates with separate runtime. Ultimately, actual battery life depends entirely on individual usage patterns and conditions.

System Requirements

The watch requires minimum supported versions:

• Android 8.0 or higher
• iOS 9.0 or higher
  Before purchasing, users should carefully verify their device's compatibility.
