compare the wrist raise between shiningintl watch 1st generation and apple watch

Finally, I got the smart watch at www.shiningsmart.com. here is some insteresting comparing between the apple watch and the MTK2502c watch, I first go to the http://ift.tt/297Qjtt ,that is the description about the watch function. I found something insteresting, the realization of the wrist raise function is totally different, I can't say which one is better, but I think the apple watch must waist more battery, and it is too sensitive to wake up the screen.
1. slowly and slightly move your hand up,test result:

in this compare, the apple watch will wake up its screen ,but the shiningsmart MTK2502c won't

2.in this test, the shiningsmart MTK2502c will easily turn on its screen

for a conclusion, it is use different algorithm between the apple watch and shiningsmart MTK2502C watch,
the apple watch will detect any movement , and wake up the screen with slightly movement, but the shiningsmart MTK2502C won't wake up screen with very slow movement, but if you just turn around your wrist, then it know you need to look at the screen of the watch, then turn it on?
so which one you would like to ?and which one is reasonable?
