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
