Countdown Timer
The countdown timer can be set within a range of one
Timekeeping Mode time
minute to 60 minutes. The currently selected alert
operation (beeper or vibration) is performed when the end
of the countdown is reached. The countdown timer has
two modes: auto-repeat and elapsed time. A progress
alert (beeper or vibration) signals the progress of the
countdown. All of this makes the countdown timer a
valuable tool for timing the start of a yacht race.
• You can select either beeper alert or vibration alert for
the alarm. The explanations in this section are based on
Minutes Seconds
the beeper alert, unless stated otherwise.
• All of the operations in this section are performed in the

Configuring Countdown Timer Settings
The following are the settings you should configure before actually using the
countdown timer.
Countdown start time and reset time
Timer mode (auto-repeat, elapsed time)
• See "To configure countdown timer settings" for information about setting up the
timer.
Reset Time
You can set a "reset time," which is a kind of alternate countdown start time. After you
set a reset time, you can recall with the press of a button any time a countdown
operation is in progress.
Timer Mode
The countdown timer gives you a choice of two modes: auto-repeat and elapsed time.
Auto-repeat
Auto-repeat automatically restarts the countdown from the countdown start time
whenever zero is reached.
• Auto-repeat mode is best when timing the starts of match races.
• Even if you start a countdown operation from the reset time, the countdown
automatically restarts from the countdown start time whenever it reaches zero.
• Auto repeat timing repeats up to seven times.
Elapsed Time
When the end of the countdown is reached in the elapsed time mode, the timer
automatically switches to an elapsed time measurement operation.
• The elapsed time mode is best when timing the speed of yachts during ocean races.
• The elapsed time operation is performed in one-second increments up to 99 hours,
59 minutes, 59 seconds.
Countdown Timer Alert Operations
While a countdown is in progress, the watch performs various different alert
operations, so you can keep informed of the countdown status, without looking at the
watch display. The following explains each of the countdown timer alert operations.
Countdown End Alert
The following countdown alert operations are performed for each of the final ten
seconds of the countdown, and when the countdown reaches zero.
Countdown
Final seconds 10 through 6 (5 times)
Final seconds 5 through 1 (5 times)
When the countdown reaches zero
• Except in the Stopwatch Mode, all buttons are disabled while a countdown end alert
operation is being performed.
Progress Alert
There are two types of progress alert: a reset time alert and a reset period progress
alert.
Reset Time Alert
The reset time alert is similar to the alert operations performed for each of the final 10
seconds of a countdown. For the reset time alert, the watch performs an alert
operation for each of the final 10 seconds before the reset time is reached.
• Except in the Stopwatch Mode, all buttons are disabled while a reset time alert is
being performed.
Reset Period Progress Alert
The reset period is the portion of the countdown between the reset time and zero.
During the reset period, the watch performs an alert operation at the top of each
minute, and at the point 30 seconds before the end of the countdown is reached. Each
reset period progress alert operation consists of four short beeps or two vibrations,
depending on the type of alert that is selected.
