[Setting the Date]

The calendar function of this watch is a full-auto
calendar that changes the year, month and date
automatically, including leap years.
1. Turn the crown to switch the watch to the time/
calendar [TME] mode.
2. When the crown is pulled out to Position 1 (date
correction position), the second hand rapidly
advances to the month display position stored in the
memory, while the function hand moves to the year
display position (number of years elapsed since
the most recent leap year), after which both stop.
Note: If the crown is pulled out to Position 1 when
the date is changing, the second hand
advances rapidly after the date changes.
3. Click (turn) the crown to the left to set the date.
• Clicking the crown once to the left causes the
function hand to make four revolutions and the
date to be corrected by one day.
• Turning the crown rapidly (continuously clicking
two or more times) causes the hand to advance
continuously. When stopping the hand, click the
crown once to the right or left. When the hand is
stopped manually, it stops automatically after
being advanced 31 days.
4. Pressing button (A) allows correction of the year
(number of years elapsed since the most recent
leap year).
Press button (A) and align the function hand at
the position corresponding to the year (number of
years elapsed since the most recent leap year).
*Interpretation of Year/Position of Function Hand*
Leap year:
1 year after most recent leap year: 6 min position
2 years after most recent leap year: 12 min position
3 years after most recent leap year: 18 min position
0 min position
5. Pressing button (B) allows correction of the
month. Press button (B) and align the second
hand at the position corresponding to the month.
6. Return the crown to the normal position after setting
the date. The watch will resume keeping time once
the second hand catches to the current seconds.
<When the calendar has been set to a
non-existent date>
When the crown is returned to the normal position
from the date correction mode, the watch switches
to the first day of the following month.
Example: February 29, 30 or 31 in an ordinary year
->March 1
February 30 or 31 in a leap year
->March 1

11. Using the Chronograph

The chronograph is able to measure time up to a
maximum of 59 minutes, 59.95 seconds in 1/20th
second units, after which resets to 0 seconds.
[Explanation of Hands During Chronograph
Measurement]
When the crown is turned and the mode hand is set
to the chronograph [CHR] mode, the second hand
and function hand are rapidly advanced to the 0
position and the watch enters the chronograph mode.
• Second hand:
Switches to the chronograph second hand. The
second hand advances rapidly and makes one
revolution only when starting at 0 seconds, after
which it moves in 1 second increments to measure
chronograph seconds.
• Function hand:
Switches to either chronograph minutes or
chronograph 1/20th seconds. The function hand
moves in one minute increments to measure
chronograph minutes. When button (B) is pressed
when the chronograph is stopped, the function
hand switches to 1/20th seconds display during
time button (B) is pressed.
