[Procedure for Setting Time and Date]
Setting the Day
1. Pull the crown out to the time correction position (second position).
2. Turn the crown to the right (clockwise) and set the day to the current day.
• e displayed day begins changing at around 12:00 AM and nishes at about 5:00

Set the moon mark while referring to

<Reading the Moon Phase>
The moon phase display does not display the shape of the moon itself, but rather
simply indicates the moon phase. It can be used to provide an approximate
indication of the moon phase.
New moon
Moon age:0
(spring tide)
First quarter
Moon age:
approx.7
(neap tide)
Full moon
Moon age:
approx.15
(spring tide)
Last quarter
Moon age:
approx.22
(neap tide)
<For More Accurate Setting of the Moon Phase>
e moon phase can be set more accurately by setting the time during a new moon
(when the moon mark cannot be seen: moon phase: 0) or during a full moon (when
the moon mark is directly above in the 12:00 direction : moon phase: 15).

[Helpful Hint for Setting the Time Accurately]
After first stopping the second hand at the 0 seconds position, advance the hour
hand and minute hand 4-5 minutes past the correct time and then turn it back in the
counter-clockwise direction to the correct time to accurately set the time.
[Notes]
• If the date is corrected when the time on the watch is between 9:00 PM and
12:00 AM, the date may not change on the following day. Avoid correcting
the date during this time.
• The calendar operates based on a 31-day month. Correct the date by turning
the crown to the to the left to set to the rst day of the following month in
months with less than 31 days (months with 30 days and February).
• Avoid correcting the month when the date hand indicates a date from the
31st to the 2nd. If you want to correct the month during this time, wait until
the date hand is outside the range of the 31st to the 2nd. Then reset the date
hand to the correct date.
• When turning the crown to the left (counter-clockwise) when correcting the time
or day, the changing of the date may change a day late during normal use.
