Before Use
Before using this watch, please check the reference positions of each hand
using the following procedure to ensure that each function operates
properly. (Reference position: The initial position of each hand to ensure that
this watch functions properly).
1. Confirmation of the reference position.
(1) Put the crown in the normal position.
• Press button C for at least two seconds to switch to the Chronograph
display. Check that the hands are at the positions in fig 1.
Chronograph second hand: 00.00 seconds.
Year and month hands: 00.00 (12.00 position)
• Press button A for at least 2 seconds and check that the date hand is at the
position shown in fig 1.
Date hand: (Between 31 and 1)
(2) Once you have confirmed that the hands are at the reference position,
press button C for at least 2 seconds to return the watch to the calendar
display.
• If the hands are not at the reference position, set the reference position of
each hand by following the procedure described in “5. Setting the
Reference Position”

Fig 1. Confirmation of Reference Position

Setting the Reference Position
The hands of the watch will not indicate the correct positions unless the
reference position is set properly. If the reference position has changed, reset it
by following the procedure described below. (The reference position must also
be reset when the battery has been replaced).
1. Perform the All-Reset procedure (see fig 2).
(1) Pull out the crown to the 2nd position.
(2) Press buttons A, B and C simultaneously.
(3) When the buttons are released, the hands will move in the order of the
chronograph hand, date hands and year and month hands. A tone will sound
confirming that All Reset has been performed when this procedure is
complete.
If the crown is returned to the normal or 1st position without setting the
reference position after performing the All-Reset procedure, the reference
position failure alarm will be activated. At this time, the date hand will turn
counter-clockwise indicating that the reference position has not been set.
When this happens, pull out the crown to the 2nd position again, and
perform the procedure for setting the reference position.

Fig 2. Perform the All-Reset procedure

2. Setting the reference position (see fig 3).
(1) Press button A and set the year and month hands to 00.00
(2) Press button B and set the chronograph second hand
to 00.00 seconds.
(3) Press button C and set the date hand to the position.
• Pressing button A, B or C continuously causes the hands to advance
rapidly.
(4) Always make sure to return the crown to normal position.
• After setting the reference position, always make sure to reset the time.

sound at the correct time shown on the basic clock.
(1) Pull out the crown to the 2nd position so that the second hand stops at
0 seconds.
(2) Turn the crown in the clockwise direction (so that the hour and the
minute hands rotate clockwise) to set the day.
• The day can be corrected rapidly by moving back and forth between
9.00pm and 1.00am
(3) Turn the crown either to the right or left to set the hours, minutes and
24 hour hand to the current time.
