3.Rotate the crown to move the x Second Hand to the city code you want to select as the World Time City.

•Each time you select a city code, the z Hour Hand, c Minute Hand, and n Day Indicator move to the current time and day for that city code. For details about city codes, see the “City Code Table” at the back of this manual.

•If you think that the time indicated for the selected World Time City is not correct, it probably means that there is something wrong with your Home City settings. Use the procedure under “To confi gure Home City settings” (page E-37) to correct the Home City settings.

4.Hold down Afor about one second to cycle through the summer time settings as shown below.

Using the Stopwatch

You can use the Stopwatch Mode to measure elapsed time and lap times, and to recall lap times. Up to 10 lap times can be stored in memory. There is also memory to record the fastest lap time. Though no more lap times are stored after 10 times are in memory, the fastest lap time continues to be updated as required. Starting a new elapsed time operation clears all of the memories (including fastest lap time).

What is a lap time?

A lap time is the time elapsed over a specific segment of a race. Example: Car race on an oval track

Lap 1

•Each press of Brecords a lap time. You can record up to 10 lap times. After that, you can still perform lap time operations, but they will not be recorded.

• After 10 lap times are recorded, the b Lower Dial Hand will point to the

mark.

This indicates that no more lap times will be recorded.

 

•If you perform a lap time operation that is not recorded (because 10 times are already in memory) and that lap is the fastest lap, it will be recorded as the fastest lap.

•Performing a new elapsed time operation after resetting the stopwatch will delete previously recorded lap times.

•An ongoing elapsed time measurement operation is not affected by pulling out the crown.

•The x Second Hand, which indicates the 1/20 (0.05)-second count during stopwatch operation, moves only 30 seconds after an elapsed time measurement operation is started or restarted, or after a lap time is cleared. After that, the

x Second Hand stops.

•When elapsed time passes 60 minutes, the z Hour Hand and v Upper Dial Hand will perform one full rotation.

To recall lap data

1.While in the Stopwatch Mode, pull out the crown to enter the Data Recall Mode.

2.Rotate the crown to select other laps.

•The b Lower Dial Hand will indicate the lap number of currently shown time.

•The b Lower Dial Hand will indicate FL (fastest lap) when the fastest lap time is shown.

3.To return to the Stopwatch Mode, push the crown back in.
