[AM/PM checking] When setting the hour hand, check that AM/PM is correctly set. * When setting the time by advancing the hands, turn the hour hand past the 3 o'clock marker. If the date advances, the time is set for the AM period. If it does not change, the time is set for the PM period. * When setting the time by turning back the hands, turn the hour hand past the 9 o'clock marker. If the date moves back, the time is set for the PM period. If it does not change, the time is set for the AM period. 9 [Setting the time between 9:00 p. m. and 3:00 a. m. ] * If the time is adjusted to the time period between 9:00 p. m. and 3:00 a. m. , the date may not change properly. The watch, however, will indicate the date properly after 3:00 a. m. * To prevent this from occurring, first turn back the hour hand past 9:00 p. m. , checking that the date moves back to the previous day, and then, advance the hands to the desired time. q When setting the minute hand, advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact time. English DAY SETTING q The day changes between 11:00 p. m. while the watch is in operation and also when it is changed manually by turning the hands. q Do not change the day between 10:00 p. m. If it is necessary to set the day during that time period, first change the time to any time outside it, set the day and then reset the correct time. HOW TO CHECK THE CALENDAR q If the crown is pulled out to the second click instead of the first click and pushed back in to the normal position, the watch will not show the calendar. q Do not leave the crown at the first or second click when you use the watch, as this will shorten the battery life. q Note on the leap second One day normally is said to consist of 86, 400 seconds. In fact, it can be longer or shorter than this because of irregular changes in the rotation cycle of the earth. When the accumulated fluctuations in the length of a day total plus or minus one second, one 10 second must then be added or subtracted as a correction factor. This is known as a "leap second". The leap second correction is executed every year or two simultaneously throughout the world on the basis of information collected by astronomical observatories all over the world.
