Using the Stopwatch

The stopwatch measures elapsed time and split times.
Hand Functions
x Second Hand: Indicates the stopwatch 1/10-second
b Left Dial Hands: Indicate the stopwatch minutes and
n Right Dial Hand: Indicates the stopwatch 1/100-second
E-44
Note
The Stopwatch Mode can indicate elapsed time up to 23 minutes, 59.99 seconds.
D button operation (split, reset) is disabled while hands are moving at high speed
following a reset operation and when transitioning from a split time back to normal
elapsed timekeeping.
Once started, stopwatch timing continues until you press B to stop it, even if you
exit the Stopwatch Mode to another mode and even if timing reaches the stopwatch
limit defi ned above.
The x Second Hand indicates the 1/10-second count for the fi rst 30 seconds of a
stopwatch elapsed time operation. After that, the hand stops at 12 o'clock.
1/10-second timing continues internally after the fi rst 30 seconds, and the
x Second Hand will jump to the current value whenever B (Stop) or D (Split) is
pressed.
Though the n Right Dial Hand is stopped while an elapsed time measurement
operation is in progress, the watch keeps track of the 1/100-second count
internally. The n Right Dial Hand will jump to the current 1/100-second reading
whenever you stop the stopwatch or perform a split time operation (page E-45).

probably means that there is something wrong with your Home City settings. Use

The watch's built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to
change it except after you have the watch's rechargeable battery replaced or after
power drops to Level 3.
