It depends what you want to do with the smartwatch, besides changing faces (called dials by Chinese manufacturers). For instance, full smartwatch with all features of a standard smartphone, including sending and receiving calls, camera to scan QR-codes, etc. For that, the best one hands down is the following:
S12 Ultra 4G Android, Amoled Display TEST Review, Telescopic Camera 4/64GB SimCard WiFi+Lte S9-CDS9
