2.4 IP68 Dustproof & Waterproof Industrial Rating

This watch complies with IP68 industrial dust and water resistance standards, exceeding basic 3ATM splash-proof specifications. It blocks daily dust accumulation, handwashing splashes, sweat corrosion and short-term cold water submersion.

The following activities will cause permanent internal structural damage and void the factory’s hardware warranty: diving, snorkeling, high-pressure water jet flushing, prolonged swimming, hot water bathing and sustained sauna steam exposure.

Internal rubber sealing gaskets experience natural aging with daily wear, which gradually reduces dust and water barrier performance over months of regular use.

3. Biometric Sensors & Health Tracking Functions

Disclaimer: All collected biometric data including heart rate, SpO2, blood pressure trends and sleep cycle records serve only as consumer-level daily reference. This wearable is not FDA or medical-grade certified medical equipment. It cannot be used for clinical diagnosis, disease assessment or treatment guidance. Users experiencing persistent physical discomfort or abnormal vital signs must consult a licensed medical practitioner promptly.

Sensor reading accuracy is affected by wrist strap tightness, arm hair coverage, wrist tattoos and ambient temperature. The watch delivers over 97% heart rate detection accuracy under standardized laboratory testing conditions.

3.1 Full-Time Vital Sign Monitoring

7. Frequently Asked Questions

Q1: What core advantages does the AMOLED screen bring compared to conventional LCD smart watches?

The 390*390 AMOLED panel delivers higher contrast, deeper black rendering and lower standby power consumption. The built-in AOD always-on mode allows constant time display without waking the full screen, improving daily usability for business users.

Q2: Can I wear this watch with metal or leather straps during hand washing or swimming?

Milanese metal mesh and leather straps do not carry dustproof or waterproof construction. All water contact scenarios require swapping to the original silicone strap to protect the watch internal sealing structure.

Q3: Is the IP68 rating suitable for long-duration swimming or hot bath use?

IP68 only supports short cold water submersion, daily splashes and sweat resistance. Long swimming, diving, hot water bathing and sauna exposure will degrade internal rubber gaskets and void the warranty.

Q4: What custom solutions are available for business wearable brand bulk orders?

We offer full one-stop private-label customization including logo engraving, business-oriented color matching, premium gift packaging upgrade, AMOLED & NFC firmware tuning and exclusive branded APP development, supported by formal NDA confidentiality agreements for all custom projects.

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.
