<Time Setting Warning Feature>
After the watch has been recharged after having stopped due to being undercharged,
although the watch hands will begin to move, the time will not be correct. The second
hand will begin irregular 2-second interval movement (moving irregularly once every 2
seconds) at this time indicating that the time is incorrect. Reset the time after suffi-
ciently charging the watch by referring to Section 6 entitled, "Charging Procedure”.
When the time has been reset, the second hand will no longer move irregularly in two
second intervals, and return to either 1-second or 2-second interval movement. In the
case of 2-second interval movement, the watch must be additionally charged.
