Congratulations upon your selection of this CASIO watch. To get the most out of your 

purchase, be sure to read this manual carefully.

 For a watch with an elapsed time bezel  

 

•

Rotate the elapsed time bezel to align the 

 mark with the 

minute hand. After a certain amount of time has elapsed, 

read the graduation on the elapsed time bezel which the 

minute hand points to. The elapsed time is indicated.

 Some water resistant models are equipped with a screw 

 

•

lock crown. 

 With such models, you must unscrew the crown in the 

 

•

direction noted in the illustration to loosen it before you can 

pull it out. Do not pull too forcibly on such crowns. 

 Also note that such watches are not water resistant while 

 

•

their crowns are loosened. Be sure to screw the crowns 

back in as far as they will go after making any setting.

 Button operations are indicated using the letters shown 

 

•

in the illustration.

Your watch lets you set two different times: one time with the hour and minute hands, 

and another time with the 12-hour and 24-hour hands.

The time indicated by the hour hand and minute hand (Dual Time) can be set to the 

time you want without stopping watch operation.

You can set the 12-hour and 24-hour hands to your basic time (the current time in the 

time zone where you normally use the watch), and change the hour hand to any other 

time (Dual Time) you want (current time in a city you are visiting, etc.).

When setting the time, make sure that the date setting is correct. If it isn’t, correct the 

date setting.

 As the second hand reaches the 12 o’clock position, pull the crown out to the 

1. 

second click. This will cause the second hand to stop.

hand and minute hand. Though the minute, hour, 12-hour, and 24-hour hand 

movements are coordinated with each other, the hour hand can be moved 

independently to indicate a second time (Dual Time). For more information about 

setting the hour hand, see “To adjust the hour hand setting (Dual Time)”.
