C confirmation of reception result 11

Although the standard time radio waves used by radio wave watches are transmitted continuously 24 hours a day transmission may be interrupted for reasons such as maintenance and inspections this watch will continue to keep the correct time at an accuracy of within 15 seconds per month even if it is unable to receive standard time radio waves 12

D reception level and reception result 12

During the standard time radio waves are being received the shorter end of the second hand waits at the reception level position corresponding to the reception state to indicate the reception level following reception the reception result can be confirmed by pressing button a once 12

E general reference for receiving areas 12

The following provides a general reference for those areas where the watch is able to receive standard time radio waves however these areas may vary depending on the time seasonal variations and weather presence of lighting etc since this map only provides a general reference of the standard receiving areas it may not apply in some particular locations even within the range shown on the map 12

If the crown of your watch is of the screw look type operate the crown after first loosening the screw locking mechanism by turning the crown to the left when finished operating the crown turn the crown to the right while pushing in after having returned it to the normal position and tighten securely after having manually corrected the time and date or after having corrected the time difference make sure to securely tighten the screw locking mechanism of the crown after returning it to the normal position since the watch will continue to be in the hour hand and date correction mode or time difference correction mode etc if the screw locking crown is tightened immediately after completion of hand movement the hour hand will advance causing the set time and so forth to be incorrect 13

Manually setting the time and date 13

Screw lock type crown 13

This watch allows the time and date to be set manually when radio waves are unable to be received 13

1 pull the crown out to the second position the second hand rapidly moves forward or backward to the 0 seconds position and stops if the second hand is not stopped at the 0 seconds position set the reference position by referring to setting the reference position 2 turn the crown to set the minute hand when the crown is turned one click to the right the second hand makes one revolution while moving forward in the clockwise direction and the minute hand advances by one minute when the crown is turned one click to the left the second hand makes one revolution while moving backward in the counter clockwise direction and the minute hand moves back by one minute turning the crown continuously by two clicks or more causes the second hand and minute hand to move continuously turn the crown to the left or right to interrupt continuous movement of the hands 14

1 pull the crown out to the first position the watch changes to the date correction mode and the second hand moves to the position of the year and month stored in memory and stops 2 turn the crown to set the month and year turn the crown one click to the right to align the second hand at the position corresponding to the month and year when the crown is turned one click to the left the second moves backwards turning the crown continuously by two clicks or more causes the second hand to move continuously turn the crown to the left or right to interrupt continuous movement of the second hand 16

V reading the month january the january zone is between 1 00 and 2 00 february the february zone is between 2 00 and 3 00 december the december zone is between 12 00 and 1 00 16

V reading the year leap year 1st graduation of each month zone indicates a leap year 1st year after leap year 2nd graduation of each month zone indicates the second year after a leap year 2nd year after leap year 3rd graduation of each month zone indicates the third year after a leap year 3rd year after leap year 4th graduation of each month zone indicates the fourth year after a leap year 16

1 put the crown in the normal position 2 press button b once the shorter end of the second hand moves to the set or 0 position to indicate that the watch has entered the time difference correction mode 3 when the crown is turned continuously by two or more clicks the hour hand moves continuously when the crown is turned continuously to the right the hour hand moves continuously in the forward clockwise direction 17

C correcting the hour hand and date 17

Examples 17

Since the date changes in coordination with the hour hand it cannot be corrected independently the date is changed by continuously advancing the hour hand the hour hand and date can be corrected for 10 seconds after pressing button b or for 10 seconds after the hour hand has stopped moving after correcting the hour hand the watch automatically returns to the normal display if the crown is not operated for 10 seconds 17

General reference for charging times of solar powered watches 26

Note once fully charged the watch has a continuous operating time of about six months without further charging when the power save feature has been activated the watch will continue to keep the correct time for about two years however if the watch stops running as a result of being insufficiently charged a considerable amount of time is required to charge so that it starts running again as is indicated in the table it is therefore recommended to charge the watch at least once a month by exposing to direct sunlight 26

The time required for recharging varies according to the model of the watch color of the dial etc the following times are shown below only to serve as a reference recharging time refers to the amount of time the watch is continuously exposed to light 26
