Restricted Usage Scenarios

The device is not applicable for swimming, diving, high-pressure water flushing, hot water bathing and sauna steam environments. Long-term immersion and high-temperature humid environment will damage the internal sealing structure and affect the stability of ECG and PPG detection functions. Improper use will void the official warranty.

Natural Aging Attenuation Note

The internal waterproof and dustproof rubber gaskets will undergo natural aging after long-term wear and environmental erosion. The gradual weakening of protective performance is a normal physical wear phenomenon and does not belong to manufacturing quality defects.

3. Dual Sensor Technology & Professional Health Tracking

Strict Dual Non-Medical Mandatory Disclaimer: All PPG-based vital sign data and ECG waveform records collected by the VO199 are only for daily consumer wellness reference and physical trend observation. This device is a civilian health wearable, not a certified medical device. It cannot replace professional hospital ECG equipment, medical diagnosis and clinical analysis. It is not applicable for disease screening, diagnosis and treatment guidance. Users with chest tightness, palpitations, arrhythmia and other physical discomforts must seek diagnosis and treatment from licensed medical institutions in a timely manner.

The integrated high-precision PPG optical sensor and independent ECG electrode achieve over 97% baseline detection accuracy under standard laboratory conditions. Actual test results may fluctuate due to wrist strap tightness, body hair, skin tattoos, skin thickness, ambient temperature, and finger contact stability during ECG testing.

3.1 Exclusive Single-Lead ECG Waveform Detection

As the core differentiated function of VO199, the single-lead ECG detection adopts professional contact acquisition technology. Users only need to touch the side electrode with their fingers to complete short-term cardiac electrical signal collection and generate intuitive ECG waveform charts. The watch records daily cardiac activity trends, helping users intuitively perceive long-term heart condition changes, which is suitable for family daily health prevention and sub-health monitoring.

3.2 24/7 Full-Dimension PPG Vital Sign Monitoring

The built-in PPG sensor realizes round-the-clock automatic monitoring of core physical indicators, including real-time heart rate tracking, blood oxygen saturation detection, blood pressure trend analysis and daily stress level quantification. It accurately identifies light sleep, deep sleep and REM sleep cycles through sleep tracking, generates professional sleep quality analysis reports, and enables nighttime silent reminder mode to avoid disturbing rest.

3.3 Multi-Mode Light Sports Recording

It supports a variety of indoor and outdoor light sports modes such as walking, jogging, cycling and yoga. The watch independently records exercise duration, step count and calorie consumption, and stores data locally offline. After Bluetooth synchronization, all sports data is uploaded to the multi-language wellness APP for long-term archiving and trend analysis, realizing the integration of sports management and physical health monitoring.

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.
