How to enter recovery mode in a watch with one button (power)? I try to enter recovery mode in watch with one power button and no additional buttons , but failed to do that.

Is it possible to enter recovery mode with this single button ?

I try this with 2 different watch:
microwear H5,
kingwear 98

One of them is using android 5.1 , the other android 6.

Thank you
It seems that OP got an answer from Xda-developers for Microwear H5. 


  You can enter recovery mode via adb command or installing a reboot to recovery app from play store.


The adb command is the usual one for rebooting to recovery:

adb reboot recovery


The answer also applies for Kingwear KW98.
