that city code. Do not perform the next operation until these hands stop

moving.

Press 3. B to toggle the time for the currently selected city code between STD (standard time)/DST

After you specify a city code, the watch will use UTC* offsets in the World Time Mode to calculate the •

current time for other time zones based on the current time in your Home City.

Selecting some city codes makes it possible for the watch to receive the time calibration signal for the •

corresponding area automatically. See “Radio Controlled Atomic Timekeeping” for details.

Coordinated Universal Time, the world-wide scientiﬁc standard of timekeeping. The reference point for *

UTC is Greenwich, England.

Using the Countdown Timer

The countdown timer can be conﬁgured within a range of one minute to 10 minutes. You also can reset

the countdown timer to the preset “reset time” of 5 minutes with the press of a button. A progress beeper

keeps you informed of the progress of the countdown. An alarm sounds when the timer reaches zero,

and a count up elapsed time operation starts. All of this makes the countdown timer a useful tool for yacht

racing.

Hand Functions

x Second Hand:

Moves counter-clockwise to countdown the seconds. Automatically

switches to clockwise movement after the end of the countdown is reached

to count up the seconds of the elapsed time operation.

v Left Dial Hand: Moves to TR and then indicates the countdown timer

minutes.

n Right Dial Hands:

Show time elapsed after the end of a countdown is reached.

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

watch emits a longer beep to signal when the countdown reaches zero.

The countdown end beeper always sounds and cannot be turned off. •

Progress Beeper

The progress beeper sounds at the 5, 4, 3, 2, and 1-minute point, and 30-second point of the countdown.

If you set a countdown start time of 2 to 5 minutes, the progress beeper will start to sound after the •

ﬁrst minute is counted down. If you set a countdown start time of 3 minutes, for example, the progress

beeper will start to sound when the countdown reaches the 2-minute point.

If you set a countdown start time of 1 minute, the progress beeper will sound once when the •

countdown reaches the 30-second point.

The progress beeper always sounds and cannot be turned off. •
