Great price that we find today for the SG3 smartwatch that goes down to only $ 39.40, the lowest price we have found so far for this type of device. The SG3 stands out for having a high resolution AMOLED screen, the ideal display for a smartwatch, since it allows us to see it even in direct sunlight.
This smartwatch, which we can find under different Chinese sub-brands, is also very complete in terms of sensors, since we can measure blood pressure, blood oxygen and heart rate that even has the capacity to make electrocardiograms (ECG). A good alternative for those looking for a cheap smartwatch with a quality screen.
The SG3 smartwatch includes a 1.2-inch round AMOLED touch screen with a resolution of 390 × 390 pixels. Its body made of aluminium has IP68 protection that allows us to use it underwater for a limited period of time up to depths of 3 meters. As SoC it uses a Nordic nRF52840, which includes a low consumption processor with ARM Cortex-M4F core, 256 KB of RAM, 1 MB + 128 MB of ROM and Bluetooth 5.1 LE connectivity to pair it with our smartphone with Android or iOS efficiently. . The internal battery is 230 mAh, it recharges magnetically and lasts between 5 and 10 days depending on the use.
To configure it, we will use an app from where we can change the visual aspect of the main screen, check the data of our physical activity and make all kinds of adjustments.
