The watch is the basic version since it comes without bluetooth and without vibration and the functions are only to see the time and to be able to call from the sim card, the optical pph sensor to measure pressure and oxygen in the blood also works very well.

As a smartwatch, it's very good. If you let yourself be guided by the one that has NO chip input, I imagine it must be a demo and honestly it doesn't read the chip, but otherwise for the price it's okay. ????
