HOW TO USE

This watch is an automatic watch equipped with a manual winding mechanism.
•  When the watch is worn on the wrist, the motion of the wearer's arm winds the 

mainspring of the watch. 

•  If your watch is completely stopped, it is recommended that you manually wind 

the mainspring by turning the crown. 

1.  Slowly  turn  the  crown  clockwise  (the  1  o’clock  direction)  to  wind  the  main-

spring. 

*  Turning the crown counterclockwise (the 6 o’clock direction) does not wind the main-

spring. 

 How to manually wind the mainspring by turning the crown

.  Wind the mainspring until the power reserve indicator shows a full-wound state. 

The second hand will start moving.     

.  Set the time, day and date before putting your watch on the wrist.     

*  To check the winding state of the mainspring, refer to "HOW TO READ THE POW-

ER RESERVE INDICATOR " on page 16.

*  There is no need to turn the crown further when the mainspring is fully wound. But 

the crown can be turned without damaging the watch mechanism.

*  Once the watch is wound up fully, it operates for about 45 hours.
*  If the watch is used without being wound up fully, gain or loss of the watch may 

result.  To avoid this, wear the watch for more than 10 hours a day.  If the watch is 

used without wearing on the wrist; if it is used on the desk like a clock, for exam-

ple; be sure to wind it up fully every day at a fixed time.

*  If  you  use  a  watch  that  has  stopped  with  the  mainspring  unwound,  winding  the 

mainspring with the crown will not start the watch immediately.  That is because 

the mainspring torque (force) is low at the beginning of its winding due to the char-

acteristics of mechanical watches.  The second hand starts to move when a certain 

degree of strong torque is reached after the mainspring has been wound up.  How-

ever, swinging the watch from side to side to forcibly turn the balance can start the 

watch sooner.
