Timekeeping
You can adjust the Home Time city date and time in the Timekeeping Mode.
• The analog time of this watch is synchronized with the digital time. The analog time
setting is adjusted automatically whenever you change the digital time.
• If the analog time does not match the digital time for any reason, use the procedure
described under “To adjust home positions” (page E-42) to match the analog setting
to the digital setting.
• Pressing D in the Timekeeping Mode toggles digital display between the Home City
Date and Home City Time.

You can use the stopwatch to measure elapsed time, lap
times and split times. If you specify a distance value, the
stopwatch also will calculate and display speeds.
• The digital display range of the stopwatch is 99 hours,
59 minutes, 59.999 seconds. The stopwatch continues
to run until you stop it. If it reaches the above limit, it will
restart the time measurement from zero.
• The stopwatch operation continues even if you exit the
Stopwatch Mode. If you exit the Stopwatch Mode while a
stopwatch operation is in progress, the segments along
the top of the upper digital display (upper display
segments) will indicate the seconds of the current time.
Each segment represents one second. This is to let you
know that a stopwatch operation is in progress.
• All of the operations in this section are performed in the
Stopwatch Mode, which you enter by pressing C (page
E-7).

5. Press A to exit the setting mode.
• The day of the week is displayed automatically in accordance with the date (year,
month, and day) settings.
12-hour and 24-hour timekeeping
• With the 12-hour format, the PM indicator (P) appears for times in the range of noon to
11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
the PM indicator (P).
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
Important!
• Check to make sure that the speed hand is not moving before you perform any
Stopwatch Mode button operation.
Specifying a Distance Value
You can use the procedure below to specify a distance value, if you want. If you
specify a distance value, the watch will calculate and indicate speed for certain
stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you want.
Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0
miles.
• No speed calculation is performed when 0.0 is specified as the current distance
value.
• For lap time readings, you can specify either the lap distance (when all the laps are
the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the
watch will indicate a speed each time you take a split reading, they will be based on
the total race distance, and so they will not indicate actual intermediate split speeds.

Time Measurement
You need to specify either lap time (page E-20) or split time (page E-22) measurement
before you start a stopwatch operation.
• If you want to measure total elapsed time, select split time measurement.

• This is the distance value setting mode.
3. Press C to move the flashing between the values on
the left side and right side of the distance value decimal

4. While a distance value is flashing, use D (+) and B (–)
to change it.
• You can specify a distance value in the range of 0.1 to

• If you have a distance value (page E-15) specified for the current elapsed time
measurement, the upper display segments and speed hand will indicate the speed
when you press D to stop the elapsed time operation.
• After pressing D to stop an elapsed time operation, you could press D again to
restart from the point where you left off.
• While an elapsed time measurement operation is being
performed in the Stopwatch Mode, the watch will
indicate a speed value, which is calculated based on the
distance you specified and the elapsed time.
The speed value is indicated as described below.
Speed hand: Up to 100
Upper display segments: 100 unit
A 1000 indicator points to 1000 (located to the right of
the upper display segments) when the speed value
exceeds 1000.
• The speed hand indicates speed values less than 100.
Only even-numbered values are indicated.
•
Speed can be indicated from 0 to 1998. OVE R is indicated
by the speed hand when the speed exceeds 1998.
