Chinese Smart Watch recommendations

Please recommend me a good chinese smart watch? I have gone through Amazon and ******** however its my first time into this and I rather buy something with recommendations from you guys. I understand its pretty much what you pay is what you get but I do not wish to buy an expensive Gear or Apple iWatch right now. Basically Im looking for something which is less than $40. I dont care about all the bells or whistles as long as it shows me time, shoes me text messages, has as good battery life and hopefully have face plate changes. Really dont care about making calls, or other sensors, or video or photo recording etc.

The few models that I saw were. No 1 G2, GV08, M26 and U80.
