Why don't you simply turn the watch upside down on the wrist? AFAIK, the setting left/right wrist is just for detecting the gesture, not for reversing the sense of the display. At least this is how it works on the devices I know. I am not familiar with Vivosmart 5.
Yea, seems to be the case. I think it's an oversight with the clock face design. If they had stacked the time vertically like the others it would be fine.
