Swapping your Home City and World Time City

You can use the procedure below to swap your Home City and World Time City. This capability can come in handy when you frequently travel between two locations in different time zones.

The following example shows what happens when the Home City and World Time City are swapped while the Home City originally is TOKYO (TYO) and the World Time City is NEW YORK (NYC).

ξPressing Bagain while a split time is indicated will cause the hands to jump to a new (current) split time.

ξPressing Awhile a split time is indicated will stop the elapsed time operation, causing the hands to jump to the stop time.

Note

ξThe Stopwatch Mode can indicate elapsed time up to 1 hour, 59 minutes, 59.95 seconds. Elapsed time measurement will stop automatically when the maximum time is reached.

ξThe display illustration on page E-33 shows a stopwatch reading of 20 minutes, 45.10 seconds.

ξPressing Bwill not perform a reset operation while the hands are moving to elapsed timekeeping after you enter the Stopwatch Mode.

ξThe , Lower Dial Hand indicates the 1/20 (0.05)-second count for the first 30 seconds of a stopwatch elapsed time operation. The x Second Hand will jump to the current value whenever A(Stop) is pressed.

E-34

ξIf you do not perform any operation with the crown for about two minutes after pulling it out, crown operations will become disabled and the watch hands will no longer move when you rotate the crown. If this happens, push the crown back in and then pull it out again.

To start an Auto Start operation

1.In the Stopwatch Mode with the elapsed time reset to all zeros, press B.

ξThis causes the b Small Minute Hand, n Small Hour Hand, and m Small Hour Hand (24-hour) to move to the current Auto Start time.

ξPress Bto toggle between the normal stopwatch screen and the Auto Start time screen.

2.While the Auto Start time is indicated by the hands, press A.

ξThis starts the countdown from the Auto Start time.

ξFor information about button operations after the Auto Start starts elapsed time measurement, see “To measure elapsed time” (page E-33) and “To measure split times” (page E-34).

Note

ξTo interrupt the countdown and immediately start the elapsed time operation, press A.

ξYou can perform all normal stopwatch button operations after the elapsed time operation starts.

ξAuto Start is turned off automatically when you reset the stopwatch to all zeros after the current elapsed time operation. However, you can recall the last Auto Start time you set by pressing B.

Auto Start

Auto Start starts a countdown from a speciÞ ed start time (Auto Start time), and automatically starts elapsed time measurement when the countdown reaches zero.

Hand Functions

bSmall Minute Hand: Auto Start seconds

nSmall Hour Hand: Auto Start minutes (0 to 60)

mSmall Minute Hand (24-hour): Auto Start minutes (0 to 119)

 

To set the Auto Start Time

 

ξ You can specify an Auto Start time within the range of 0 to 119 minutes and



59 seconds.

 

1.In the Stopwatch Mode, pull out the crown to the Þ rst click.

2.Rotate the crown to specify the Auto Start time seconds setting.

ξYou can use high-speed movement (page E-3) when performing the above step.

ξChanging the seconds setting will also cause the minutes setting to change.

3.Press C.

4.Rotate the crown to specify the Auto Start time minutes setting.

ξYou can use high-speed movement (page E-3) when performing the above step.

5.Push the crown back in.

Adjusting Home Positions

Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able to perform the signal receive operation.

The watch automatically corrects for deviation of the x Second Hand, c Minute Hand, and z Hour Hand. You also can trigger hand position adjustment manually, if you want.

ξThe v Hour Hand (24-hour)is adjusted simultaneously with the z Hour Hand.

If you note that the position of the b Small Minute Hand, n Small Hour Hand, m Small Hour Hand (24- hour), , Lower Dial Hand, or . Day Indicator is off, trigger home position adjustment manually.

ξThe m Small Hour Hand (24-hour)is adjusted simultaneously with the n Small Hour Hand.

Note

ξAny time after you enter the home position adjustment mode in step 1 of the following procedure, you can return to the Dual Time Mode by pushing the crown back in. In this case, any adjustments you made before the watch returned to the Dual Time Mode will be applied.

ξLeaving the crown pulled out for more than approximately 30 minutes without performing any operation will automatically cause crown operations to become disabled. If this happens, press the crown back in, pull it out, and then start the operation over again.

ξPushing the crown back in will return to the Dual Time Mode, with any hand adjustments you have made up to that point in effect.

6. After conÞ rming that the b Small Minute Hand is at the proper home position, press C. This will advance to n Small Hour Hand home position adjustment.

ξ If the n Small Hour Hand moves to 12 o’clock, it is in the correct home position. If it doesn’t, rotate the crown to move it to 12 o’clock.

ξ The m Small Hour Hand (24-hour)moves simultaneously with the n Small Hour Hand. If the hands are not at 12 o’clock, advance the n Small Hour Hand until they do.

7. After conÞ rming that the n Small Hour Hand is at the proper home position, press C. This will advance to , Lower Dial Hand home position adjustment.

ξ If the , Lower Dial Hand moves to 12 o’clock, it is in the correct home position. If it doesn’t, rotate the crown to move it to 12 o’clock.

8. Push the crown back in to return to the mode you entered from.

ξ This will cause the hands to return to their normal positions and resume regular timekeeping. Wait until everything stops moving before performing any other operation.
