First impressionsoverview of features

As mentioned earlier S10 Smartwatch is a budget smartwatch and considering its price is very well made. The bezel is made of stainless steel. The watch face is covered with a corning glass screen. We have received a sample of S10 with a stainless steel band in black (a leather band and silicone are also available). The whole makes a very good impression. The Smartwatch looks really good. The smartwatch looks really good. On the right side of the clock face, there are 3 function keys: Start (enter key), Menu (option key) and Back(return key/press and hold to turn on/off). On the underside (typically) there is a heart rate monitor and pins for charging. Below pictures.

Unfortunately, despite the nice design, the color TFT display is small and located in the center of the clock face. This is clearly seen in the picture below. On the market you can find many smartwatches with full digital display on the whole clock face. In S10 it’s a big disappointment.

The user has a choice of 4 clock dials, 3 of them can find health data, Bluetooth connection time and battery status. 

Like most smartwatches and smart bracelets, the NO.1 S10 Smartwatch has the familiar features: Heart Rate Monitor, Sleep Monitor, Multi-sport Modes (Hiking, Pedometer, Basketball, Badminton, Table tennis, Cycling, Running, Football), Call and Message Reminder, Notifications, Reject Call, Alarm, Sedentary reminder, Camera remote control, Anti-lost, Stopwatch, Compass, Vibration. S10 has an IP68 waterproof, so you can swim in it. Below pictures.

NO.1  S10 smartwatch has a 350mAh battery that lasts up to 9 days. The charging over 2 hours. The smartwatch has sports/V4.0 firmware (V160.4.0).  S10 smartwatch works with a dedicated application called WearHealth (downloadable on Google Play and App Store).  The application works very well, and the presented data is well legible. Unfortunately, our sample (we hope only ours) S10 smartwatch had problems with the firmware (probably). Every few hours smartwatch resets, then automatically switched functions in the menu and stopped at the stopwatch and launched it. It was very annoying and we could not collect data for the whole day. Below are several screenshots from the WearHealth application. 


NO.1 S10 is a great made and great-looking smartwatch. Unfortunately, it does not offer anything extraordinary that you could not see in a smart bracelet. So it visually looks like a smartwatch but has features like most smartbands. The digital screen is small and does not cover the whole clock face. Taking into account the budget price, you can find better smartwatches on the market with a full digital dial and cheaper, eg Alfawise T1 ($27.99). Unfortunately for the disadvantage of the problems with the operation of the watch (resetting and loss of health data). 2 years ago we tested NO.1 A10, did a lot of change? check it out yourself. Of course, the choice is yours.
