Read This Before You Set the Time and Date!
The time setting of the Dual Time City as well as all of the times in the World Time
Mode are based on the current time you set for your Home City in the Timekeeping
Mode. Because of this, make sure you select a city code for your Home City (the city
where you normally use the watch) before you set the time and date.
• For full information on city codes, see the “City Code Table”.

Week Number
The week number shows the number of the current date in the current year. You can
select from among the following three types of week counting methods.
To count like this:
Start each week from Monday, and count the week that contains
the first Thursday as the first week of the year.
• This counting method is specified by ISO8601.
• Due to the ways that weeks are counted, the year of a particular
week may be different from a date that occurs during that week.
Example: January 1, 2005 is Week 53 of 2004
Start each week from Monday, and count the week that contains
January 1 as the first week of the year.
Start each week from Sunday, and count the week that contains
January 1 as the first week of the year.

Stopwatch
The 1/1000-second stopwatch measures elapsed time, as well as lap/split times, and
has an Auto-Start feature. Measurements taken using the stopwatch can
be stored in memory for later recall with the Recall Mode.
• “Lap time” is the time spent to cover a specific segment of a race, such as one lap
around a track. “Split time” is the time spent from the beginning of a race up to a
certain point.
• For information about how data recorded with the stopwatch is stored in memory,
see “Memory Management”.
• The stopwatch measurement operation continues even if you exit the Stopwatch
Mode.
• The stopwatch continues to run, restarting from zero after it reaches its limit, until
you stop it.
• All of the operations in this section are performed in the Stopwatch Mode, which you
enter by pressing C.
• While the stopwatch is stopped and reset to all zeros, you can press B to switch
between the elapsed time and lap time screens.

• The watch’s memory can store up to 99 lap times. If you stop an elapsed time
operation during which you recorded more than 99 lap times, any lap times past Lap
99 will not be stored in watch memory. If you restart the elapsed time operation in
this case, the display will show --'--''--- for the last lap time until you record then
next lap time.
• After stopping the elapsed time operation, press B to reset to all zeros.
• One-digit lap numbers (1 to 9) are displayed using the format “LAP 1”.
Example: Lap time number 8: LAP 8
Two- and three-digit lap numbers (10 to 999) are displayed using the format “L.100”
or “L.50”.
Example: Lap time number 150: L.150
About Auto-Start
With Auto-Start, the watch performs a 5-second countdown, and the elapsed time
operation starts automatically when the countdown reaches zero. Beeper and flash
alert operations are performed for each of the final four seconds of the countdown.
• When the end of the countdown is reached, a beeper operation is performed
followed by a flash alert operation. The alerts are performed separately to avoid
putting too much load on the battery at the same time.
• When Flash Alert is turned on, the red and green LEDs at the bottom of the display
will flash in time with the Auto-Start countdown beeper.
To use Auto-Start
• To terminate an ongoing countdown and start the elapsed time operation, press D.
• To cancel an ongoing countdown and return to the 5-second countdown screen,
press B.
Memory Management
Your watch has memory for two “elapsed time records”. Each elapsed time record
contains the data (elapsed time, lap times, split times, etc.) recorded from the
beginning to the end of an elapsed time measurement.
While an elapsed time operation is in progress in the Stopwatch Mode, the two
elapsed time records in memory are one for the data being produced by the elapsed
time operation you are performing and one for the data produced by the last elapsed
time operation you completed.
When there is no elapsed time operation in progress in the Stopwatch Mode (when
the stopwatch is reset to all zeros), the two elapsed time records in memory consist of
one for the data produced by the last elapsed time operation you completed and one
more record for the elapsed time operation before the last one.
• Whenever you start a new elapsed time operation, the older record currently in
memory is deleted automatically to make room for the new elapsed time data.
• You can use the Recall Mode to view the elapsed time records that currently are in
the watch’s memory.
Elapsed Time Record Data
Each elapsed time record contains the following data.
Total elapsed time
Up to 99 lap/split time records
Start date (month, day) and time of elapsed time measurement
Best lap time and number record
• Each elapsed time record can contain up to 99 lap/split times. The watch will not
store any more lap/split times after the 99th, but the best lap record will continue to
be updated whenever a new lap time betters the time of the current best lap record.
• If there are multiple lap times in an elapsed time record that are the same as the
time of the best lap, the earliest time is used as the best lap time.
• -- is shown for the best lap time if no lap/split time operation was performed during
the elapsed time operation.
1. While the stopwatch is stopped and reset to all zeros,
press B to display the Elapsed Time screen.

stopwatch and then press B to reset to all zeros.
2. Press D to start the stopwatch elapsed time operation.
3. Press D to stop the elapsed time operation.
