English 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. q The hour hand moves in one hour increments. q When adusting the date and hour hand, turn the crown slowly. In doing so, the other hands may move slightly. However, this is not a malfunction. TIME DIFFERENCE ADJUSTMENT DURING TRIP q To put back the time, turn the crown clockwise. To advance the time, turn it counterclockwise. q When moving back the hour hand past the 12 o'clock marker to set it to a time between 9:00 p.m. and 0:00 a.m., put back the hour hand further past 8:00 p.m., and then advance it to the desired hour. TIME DIFFERENCE q The time differences and the use of daylight saving time (summer time) may change in some areas or countries when they are so decided by the countries concerned. 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 second must then be added or subtracted as a correction factor. This is known as a "leap second". 18
