FEATURES
The SEIKO Quartz Watch Cal. 6M15 is an analogue watch featuring calendar, world time, alarm and stopwatch functions.

Hour, minute and second hands and a small 24-hour hand.
■ CALENDAR
Date is displayed in numerals and month is indicated by the hour and minute hands. The second hand indicates the number of years that have passed since the last leap year. The calendar automatically adjusts for odd and even months including February of leap years up to 2099.
■ WORLD TIME
The time of 22 time zones throughout the world is displayed. Daylight saving time (summer time) and standard time of those time zones can also be displayed as required
simply by turning the crown.
• Time transfer |
|
a convenient way of using the WORLD TIME mode |
|
The time displayed in the TIME mode can easily be replaced with that of any time zone in the WORLD TIME mode. This function is very useful when you travel abroad. The time of the city you visit can be shown on the watch without resetting the hands.
■ ALARM
The alarm can be set to ring on the basis of the time of a desired time zone. It can be set on a 24-hour basis in minutes and rings once a day.
■ STOPWATCH
The stopwatch can measure up to 23 hours, 59 minutes and 59 seconds. It measures in 1/10 second increments for the first hour, and in second increments thereafter. Split time measurement is possible.

•Turn the crown to set the mode indicator to “Ø CHRONO.”.
If the hands do not return to the 12 o’clock position or the date numeral
does not appear at the center of the calendar frame, reset them following the procedure below.
* When the stopwatch is counting, press “A” to stop measurement and then press “B” to reset the hands.

1.Pull out the crown. The date returns to “1”.
* Reset of the hand or date can be made only after the date returns to “1”.
*If the date does not return to “1”, reset the circuit following the procedure in “NECESSARY PROCEDURE AFTER BATTERY CHANGE”.
2.Press “B”, “A” and “C” repeatedly but separately to reset the hour, minute and second hands to the 12 o’clock position, respectively.
*The hands move quickly if the respective buttons are kept pressed.
*The 24-hour hand moves correspondingly with the hour hand. When resetting the hour hand, check that the 24-hour hand indicates “24”.
3.Press “D” to put the date numeral “1” to the center of the calendar frame.
*By pressing “D”, the date moves back and forth repeatedly.
*The date moves quickly if “D” is kept pressed.
4.Push the crown back in to the normal position.
TIME SETTING
The time in the TIME mode advances correspondingly with the time in the WORLD TIME mode. Once the time of a desired time zone is set in the TIME mode, the time of all the 22 time zones covered in the WORLD TIME mode will be set automatically. By specifying whether the time set in the TIME mode is standard or daylight saving time (summer time), the WORLD TIME mode will automatically display the correct standard and daylight saving times for the respective time zones.
*Daylight saving time is a system adopted in some countries to make the best use of the daytime during a certain period in summer. Under this system the time is advanced one hour from the regular time.
Note: The time differences and use of daylight saving time (summer time) may change in some areas or countries when they are so decided by the countries concerned.
To set the time in the TIME mode, first select the city representing your area, set the current time of your area, and then specify the set time as daylight saving time or standard time, following the procedure below.
• Turn the crown to set the mode indicator to “TIME”.

* The hand moves quickly if the button is kept pressed.
3.Press “A” repeatedly to set the minute hand. It advances one minute with each press of the button.
* The hand moves quickly if the button is kept pressed.
* As the minute hand moves, the hour hand also moves correspondingly.

* The hand moves quickly if the button is kept pressed.
*The minute hand will not move if “B” is pressed.
*The 24-hour hand turns a full circle in 24 hours and moves correspondingly with the hour hand. When setting the hour hand, check that the 24-hour hand is correctly set.
5.Press “D”. The second hand will move to indicate “STD” (Standard Time) or “DST” (Daylight Saving Time) on the bezel/dial. With each press of “D”, the second hand indicates “STD” or “DST” alternately. If the daylight saving time is in use in your area, set the second hand to “DST”, and if not, set it to “STD”.
*If the watch is left untouched for 5 seconds with the second hand indicating “STD” or “DST”, it will automatically return to the city you have selected.
6.Push the crown back in to the normal position in accordance with a time signal. The second hand returns to the 12 o’clock position and starts moving at one-second intervals.
Notes:
1.Once the time of your area is set, the time of the other 21 time zones represented by the cities on the bezel/dial will also be set automatically.
2.While the watch displays both standard and daylight saving times for all areas year round, the user must check to see when each is in effect for the respective countries.
Checking of the time zone and daylight saving time

[To check whether the standard time or daylight saving time has been set]
1.Press “D”. The second hand points to “STD” if the set time is the standard time, and “DST” if the set time is the daylight saving time.
