HOW TO USE (FOR CAL. 9R84, 9R65, 9R15)

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.

Please see the power reserve indicator to check the level of the remaining power.

How to read the power reserve indicator

When starting to use a stopped watch, it is recommended that you turn the crown to wind the mainspring. To wind 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. Five full rotations of the crown will provide the power to run the watch for approximately ten hours.

If you wear the watch for twelve hours per day consecutively for three to five days, the watch will be fully wound.

This watch is equipped with the date display function. The date changes once every 24 hours at around midnight.

Therefore, if the a.m./p.m. is incorrectly set, the date will change around 12:00 p.m.

1. Pull out the crown to the first click.

(If the watch is equipped with the screw down crown, unscrew the crown before pulling it out.)

2. The date can be adjusted by turning the crown counterclockwise (6 o’clock direction).

First turn the crown counterclockwise until the previous day’s date from the desired date appears.

【Ex.】

If you want to set the date to “6,” set the date to “5” by turning the crown counterclockwise.

3. Pull out the crown to the second click when the seconds hand (or the small seconds hand) is at the 0 position. The seconds hand (or the small seconds hand) stops.

Turn the crown counterclockwise (6 o’clock direction) to advance the hands until the desired date appears. If the date changes, it means that the watch is set in the morning. Turn the crown further until the watch is set to the current time.

4. Push the crown back into the normal position in accordance with a time signal. The watch starts operating.

It is necessary to adjust the date after February (which has 28 days, 29 days in a leap year) and a 30 day month.

First click position

“31” is displayed instead of “1”. Pull out the crown to the first click. Turn the crown counterclockwise (6 o’clock direction) to set the date to “1”, and push the crown back in to the normal position.

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 fully 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 seconds hand (or the small seconds hand) starts moving, then pull the crown out to the second click.

3. The seconds hand (or the small seconds hand) will stop moving when the crown is pulled out to the second click. Do not stop the movement of the seconds hand (or the small seconds hand) for longer than 30 minutes. If the stoppage of the seconds hand (or the small seconds hand) movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand (or the small seconds hand) restarts moving, and then set the time.
