Green triangle shows the hour, red triangle shows the minute. Blue rectangle shows watch battery power, yellow rectangle shows phone battery power. To read battery level, if the blue or yellow rectangle is at the 15th minute marker or 3 oclock position, this means there is 25 percent of battery power left, if it is at the 30th minute marker or 6 oclock position, this means 50 percent left, 45th minute marker or 9 oclock position means 75 percent left. Battery power indicators will flash when battery power is reduced to 29% or lower, when the indicators are at the 0 to 17th minute markers.
