Today we can normally say that Chinese company No.1 is well known for making smartwatches. They normally introduce several different models every year, so the same situation is now when they have introduced No.1 F2.

Actually really cheap smartwatch with IP68 certification. Which is also at this moment on sale on Gearbest here with price only $19.99!

Anyway No.1 F2 is intended for outdoor activities, and it is based on ultra energy efficient Dialog DA14580 with Bluetooth 4.0. But if you ask your self what functions and features it has, then we can tell you that it has more or less the same functions like any other smartwatch. For example it has pedometer, sleep monitor, calorie consumption, and much much more.

Therefore it is also interesting that this smartwatch has features for monitoring ultraviolet radiation, air pressure, the altitude, and temperature. From other information we can tell you it has 1.1 inch screen where the screen is protected with mineral glass.

For this price range which is actually around $20 No.1 F2 is great choice because it has also IP68 rating. In other words it is waterproof up to 30m depth.  But what about the battery? From what we can see it is using very similar battery like any other ordinary watch, or in this case CR2450 button battery with capacity of 550mAh. And according to the company it can last approximately two years, after that you need to replace it with new battery.
