1. When the second hand is at 12 o’clock, pull out the crown to the second click to stop it.

2. Set the hands by rotating the crown. Rotate the crown to move the hands clockwise. Move the minute hand four or five minutes past the time you want to set, and then back it up to the proper setting.

3. Push the crown back in to the normal position to restart timekeeping.

1. Pull the crown out to the first click.

2. Set the day by rotating the crown.

3. Push the crown back in to the normal position.

• Avoid changing the date setting while the current time is between 9:00 p.m. and 3:00 a.m.

The stopwatch lets you measure elapsed time up to 59 minutes, 59.95 seconds.

1. Press A to start the stopwatch.

2. Press A to stop the stopwatch.

• You can resume the measurement operation by pressing A again.

• The 1/20-second hand stops moving after the first 30 seconds, but timing continues internally. The 1/20-second hand will move to the current timing value when the stopwatch is stopped.

3. Check the elapsed time.

• Press B to reset the stopwatch. This will enter the Timekeeping Mode.

Notes:

• Do not try to perform stopwatch operations while the crown is pulled out either to the first or second click. If you try to press a button, you might accidentally cause the crown to rotate and change the current time or day setting.

If the starting positions of the stopwatch second hand and 1/20 second hand become misaligned, use the following procedures to adjust the positions of the hands so they point to 12 o’clock when the stopwatch is reset.

1. Press B to reset the stopwatch, and check the stopwatch second hand, 1/20 second hand, and minute hand. They all should be at 12 o’clock.

2. To adjust the hands, pull out the crown to the second click.

3. Press A to move the stopwatch second hand to 12 o’clock.

• Holding down A will move the second hand at high speed, until you release the button.

4. Press B to move the stopwatch 1/20 second hand to 12 o’clock.

• Holding down B will move the 1/20 second hand at high speed, until you release the button.

5. After making the adjustments you want, push the crown back in to its normal position.

6. Press B to reset the stopwatch minute hand.

• Note that pulling the crown out also stops the timekeeping second hand. After performing the above procedure, you should also adjust the timekeeping setting.

For a watch with an elapsed time bezel:

• Rotate the elapsed time bezel to align the ▽ mark with the minute hand.

• After a certain amount of time has elapsed, read the graduation on the elapsed time bezel which the minute hand points to. The elapsed time is indicated.

• Some water resistant models are equipped with a screw lock crown.

• With such models, you must unscrew the crown in the direction noted in the illustration to loosen it before you can pull it out. Do not pull too forcibly on such crowns.

• Also note that such watches are not water resistant while their crowns are loosened. Be sure to screw the crowns back in as far as they will go after making any setting.
