How to install the hands

instructed below.
1. Pull out the SETTING STEM to the first click position, and set the calendar to “ the leap year,
January 1.”

Month
2. Pull out the SETTING STEM to the second click position, and turn the crown to set the 24H
contact point as illustrated below (to correct the timing of date change).
* Connect the probes of testers to “A” and “ B” portions. The 24H contact point will be adjusted, allowing
for a check of date changing status.
3. Keep the watch in this state when carrying out the installation of the hands in order
of the 24-hour hand, month indicator, hour hand, minute hand and second hand.
* When removing the hands during repair work, ensure that the calendar is set to “ the leap year, January 1”.
If the hands are removed with the calendar set to a date other than “the leap year, January 1”, the correct
position of the year may be lost.
