Operation Guide 5143
An ongoing stopwatch operation will continue even if you pull out the crown to
perform some setting operation.
In the following cases, the hands of the watch are moving, so pressing B will not
perform a reset operation.
−
While the hands are moving to elapsed timekeeping after you enter the Stopwatch
Split Mode
−
While the watch is changing dates at midnight
Once started, stopwatch timing continues until you press A to stop it, even if you
exit the Stopwatch Split Mode to another mode and even if timing reaches the
stopwatch limit defi ned above.
You can press A to start an elapsed time operation immediately after entering
the Stopwatch Split Mode, even if the watch's hands are still moving to their initial
Stopwatch Split Mode positions. Note, however, that if the stopwatch was not
reset after the last elapsed time operation, timing will restart from where it was last
stopped, and not from 12 o'clock.

Using the Stopwatch (Stopwatch lap mode)
You can use the Stopwatch Lap Mode to measure elapsed time and lap times, and to
recall lap times. Up to fi ve lap times can be stored in memory. There is also memory
to record the fastest lap time. Though no more lap times are stored after fi ve times are
in memory, the fastest lap time continues to be updated as required. Starting a new
elapsed time operation clears all of the memories (including fastest lap time).
What is a lap time?
A lap time is the time elapsed over a specifi c segment of a race.
Example: Car race on an oval track

Using the Countdown Timer
The countdown timer can be confi gured within a range of one minute to 60 minutes.
An alarm sounds for about 10 seconds when the timer reaches zero, and a count up
elapsed time operation starts.
Hands and Indicators
z Hour Hand: Indicates the elapsed time hour.
x Second Hand: Indicates countdown or elapsed

Rotate the crown to set the countdown start time.
Rotating the crown two full consecutive turns away from you will cause the
c Minute Hand to start moving clockwise. Rotating the crown another two full
consecutive turns away from you will cause the c Minute Hand to start moving
at high speed. To stop hand movement, press any button or rotate the crown one
full turn towards you.
The maximum countdown start time setting is 60 minutes. To set a countdown start
time of 60 minutes, move the c Minute Hand to 12 o'clock.
