⑤ Upon completion of setting, make sure that the time indicated is correct, and then push the crown back in. The calendar setting is now completed. Relock the crown. ⇒ "How to use the screw-lock type crown" page 16. ※ The calendar is designed to work in conjunction with the movement of the hour hand, therefore, if AM/PM is incorrectly set, the calendar will be off by 12 hours. ※ The crown can be turned in either direction to adjust the date, however, it is recommended to turn the crown in the direction which enables you to set the date with a smaller adjustment. ※ Turn the crown slowly, checking that the hour hand moves in one-hour increments. ※ When adjusting the hour hand, the other hands may move slightly. However, this is not a malfunction. Tips for more accurate time setting To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time. ① Before setting the time, make sure to wind the mainspring sufficiently. (Ensure that the power reserve indicator is showing a full-wound state.) ② When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the second hand (or the small second hand) starts moving, then pull the crown out to the second click. ③ The second hand (or the small second hand) will stop moving when the crown is pulled out to the second click. Do not stop the movement of the second hand (or the small second hand) for longer than 30 minutes. If the stoppage of the second-hand (or the small-second-hand) movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the second hand (or the small second hand) restarts moving, and then set the time. ④ If you set the time when the time the watch indicates is between 9:00 p.m. and 1:00 a.m., set the hour hand back to 8:00 p.m. temporarily, and then set the time. (This procedure is required to ensure the proper engagement of the calendar driving wheels.) 28 HOW TO USE (For Cal. 9R86, 9R66) English How to use the 24-hour hand This watch has two different types of 24-hour hand usage. 24-hour hand as an AM/PM indicator Simply using the 24-hour hand to show the 24-hour time as an AM/PM indicator. (This is the standard usage type for the 24hour hand.) Both the hour hand and the 24hour hand are indicating the Japan time 10:00 a.m. 24-hour hand as a dual time indicator Using the time difference adjustment function, set the 24-hour hand to indicate a time different from the time that the hour and minute hand indicate, which is of a place in a different time zone area with at least one hour of time difference from where you are. Hour hand: Japan time 10:00 a.m. 24-hour hand: New York time 8:00 p.m.                             (.5      (.5            Time difference adjustment function For example, while traveling abroad and staying in a place with a different time from where you live, you can conveniently set the watch to indicate the local time in the different time zone area without stopping the watch. The hour hand indicates the time of the place where you currently are, while the 24-hour hand indicates the time of the place of origin. The calendar works in conjunction with the movement of the hour hand. If the time difference is correctly adjusted, the watch displays the correct date of the place where you are staying.   How to use the time difference adjustment function ① Make sure that the mainspring is sufficiently wound and the watch is working.  ※ When setting the hour hand to use the time difference adjustment function, ensure that the watch is working. ② Unlock the crown. ⇒ "How to use the screw-lock type crown" page 16.  ③ Pull out the crown to the first click.
