Reset Time
You can set a “reset time,” which is a kind of alternate countdown start 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 mode automatically restarts the countdown from the countdown start time
you set 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.

World Time
The World Time Mode shows you the current time in 27
cities (29 time zones) around the world.
• The time settings of the Timekeeping Mode and the
World Time Mode are independent from each other, so
you must make separate settings for each.
• Whenever you change the time setting for any city in the
World Time Mode, the settings of all other cities are
changed accordingly.
• For full information on city codes, see the “City Code
Table ”.
• All of the operations in this section are performed in the
World Time Mode, which you enter by pressing C.

GMT is selected as the
city code.
• Note that the DST/Standard Time setting affects only the
currently displayed city code. Other city codes are not
affected.
• The
indicator is on the display whenever you display a
city code for which Daylight Saving Time is turned on.
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 Beeper Operations
The watch beeps at various times during a countdown so you can keep informed
about the countdown status without looking at the display. The following describes the
types of beeper operations the watch performs during a countdown.
Countdown End Beeper
The watch beeps each second of the final 10 seconds before a countdown reaches
zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than
the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal
when the countdown reaches zero.
• The countdown end beeper always sounds, regardless of the on/off status of the
progress beeper.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and a reset
period progress beeper.
• The reset time beeper and reset period progress beeper sound only while the
progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the progress
beeper is turned on, the watch beeps each second of the final 10 seconds before the
countdown reaches the reset time.
Reset Period Progress Beeper
The reset period is the portion of the countdown between the reset time and zero.
When the progress beeper is turned on, the watch emits four short beeps at the top of
each minute during the reset period, and 30 seconds before the end of the
countdown.

Countdown Timer
The countdown timer can be set within a range of one
minute to 60 minutes. An alarm sounds when the
countdown reaches zero. The countdown timer has two
modes: auto-repeat and elapsed time, and a progress
beeper signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for timing the
start of a yacht race.
• All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing
C.
