• When the 12-hour format is selected, the indicator P appears on the diaplay

5. Press D to make the display darker, or B to make it lighter.
6. After the contrast is the setting you want, press A to return to the normal
timekeeping screen.
• The day of the week is automatically set in accordance with the date.
• The date can be set within the range of January 1, 1995 to December 31,
2039.
• The watch's built-in full automatic calendar automatically makes allowances
for different month lengths and leap years. Once you set the date, there
should be no reason to change it except after the replacement of the
watch's battery.
To set the analog time
1. Pull the crown out to stop the second hand.
• If you plan to restart analog timekeeping on some time signal (from the
radio or television), pull the crown out when the second hand is at the 12
o'clock position.
2. Set the hands by turning the crown.
3. Push the crown back in to restart timekeeping.
• Analog time is kept by a mechanical timepiece. Because of this, the second
hand may not start to move exactly when you push the crown back in.
