Here is another review of another Smartwatch from No.1, the G3. This Smartwatch comes with a circular dial and looks almost like the Samsung Gear S2 Smartwatch. No. 1 G3 Smartwatch is available for $55.

Inside the box you will get the Smartwatch, user guide and magnetic charging dock.

Design and Display

As mentioned this watch looks almost similar to the Samsung Gear S2. No.1 G3 however does not come with rotating dial navigation system. G3 is using a plastic body with rubber straps. The sides where the straps are attached looks a bit weird, and especially when you are wearing the watch.

There are two buttons on the right side – both perform the same function, just that the bottom is also a power on/off button. There is heart rate sensor on the back, microphone on the left side and speaker out vent on the right side.

The back cover can be opened, inside you will find the 350 mAh battery, be careful not to pull it out completely as it is attached with wires. Below the battery there is a micro SIM slot (2G support) and next to it is the micro SD card slot (16GB max supported).

No.1 G3 sports a 1.3 inch IPS screen with 240 x 240 pixels resolution.  Color reproduction looks good, touch is smooth and viewing angles are okay.

This Smartwatch is powered by MTK2502 processor and supports Bluetooth 4.0. There is a QR code on the watch, scan that and install the Fundu App on your smartphone. After installing the app connect the watch and then you will be able to sync the data on to your smartphone. There is no need to keep the watch connected with the phone whenever you want to sync connect watch and use the sync option.

No.1 G3 smartwatch hands on

The Fundo app also comes with some watch faces that you can download and use on the No.1 G3 watch.

Performance is good, you can browse though the menu using touch – drag left to right or right to left. There is also an option to switch the menu style to angular style, something similar to as seen on the Samsung Gear S2 Smartwatch.

You can use this watch as a standalone phone for making and receiving calls. However the speaker output and sound quality is not that great.

This watch can keep track of your physical activities – steps, calories, sleep, it can measure heart rate, also comes with built in ECG, BBT and UV sensors.


The 350 mAh non-removable battery can be fully charged in 1 hours 33 minutes and you can expect battery backup of up to 24 hours with mixed usage.


This Smartwatch works with iOS and Android platforms. A good option, but the loudspeaker sound loudness and quality is not up to the mark.

No.1 G3 Smartwatch is available for $55.
