HOW TO USE (FOR CAL. 9S86, 9S66)

How to wind the mainspring

This watch is an automatic winding type (with manual winding function).

The mainspring can be sufficiently wound automatically by natural movement of the arm while normally worn on the wrist. In addition, it can be wound by turning the crown.

A stopped watch can be started by arm movement when it is worn on the wrist, however, before wearing the watch, wind the mainspring sufficiently and set the time and date. When winding the mainspring, turn the crown at the normal position clockwise (12 o’clock direction) slowly. If you turn the crown counterclockwise (6 o’clock direction), it will turn free.

The mainspring is sufficiently wound when the crown is turned approximately 45 times for Cal. 9S86 and 60 times for Cal. 9S66. When the mainspring is in the full-winding state, it is designed so that the mainspring slips if it is overwound. Therefore, it is not necessary to worry about breaking the mainspring, however, please refrain from excessive operation.

It is recommended that you wear the watch on your wrist more than 10 hours a day to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may lose or gain time. If you use the watch without wearing on your wrist, wind the mainspring up sufficiently by turning the crown by hand every day at a fixed time.

How to set the time and date

To set the time and date, set the 24-hour hand and minute hand first, and then set the hour hand and date.

When setting the time, make sure that the mainspring is sufficiently wound.

Manual date adjustment is required on the first day after a month that has less than 31 days: February, April, June, September and November.

How to use the 24-hour hand

This watch has two different types of 24-hour hand usage.

<Type 1>:

24-hour hand as an a.m./p.m. indicator

Simply using the 24-hour hand to show the 24-hour time as an a.m./p.m. indicator. (This is the standard usage type for the 24-hour hand.)

Both the hour hand and the 24-hour hand are indicating the Japan time 10:00 a.m.

9S86_Set Time-10

<Type 2>:

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:

London time 1:00 a.m.

9S86_Set Time-11

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 date 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.

  2. When setting the hour hand to use the time difference adjustment function, ensure that the watch is working.

  3. Unlock the crown.

  4. Screw down crown

  5. Pull out the crown to the first click.

How to use the bi-directional rotating bezel

Some models may have a bi-directional rotating bezel, the rim of the glass.
By utilizing the 24-hour indicators imprinted on the rotating bezel, the watch can independently display the time in one or two different time zones in addition to the time indicated by the hour hand.

【Ex.】

To set the 24-hour hand to indicate the time in Paris and Bangkok which are located in two different time zones, while setting the hour hand to display 10:08 a.m., Japan time.

To use the 24-hour indicators on the rotating bezel to indicate the hour in Bangkok.

  1. First, set the Bezel-2 mark on the rotating bezel to the 12 o’clock position.

  2. Refer to Time difference adjustment function, and set the hour and minute hands to 10:08 a.m. and align the 24-hour hand with “2” on the rotating bezel.

  3. Time in Paris is 8 hours behind Japan except for summer seasons when daylight saving time is observed.

  4. There is a +6-hour time difference between Paris and Bangkok; the time in Bangkok is 6 hours ahead of the time in Paris (when daylight saving time is not in effect). Turn the rotating bezel counterclockwise to move the Bezel-2 mark back 6 hours on the 24-hour indicators.

  5. The hour in Paris is shown by the 24-hour hand pointing to “2” (2:00 a.m.) of the 24-hour indicators on the dial (or the outer frame of the dial), while the hour in Bangkok is shown by the 24-hour hand pointing to “8” (8:00 a.m.) of the 24 hour indicators on the rotating bezel.

9S86_Set Time-15 + How to set Time(86)-15
