1. How to manually wind the mainspring by turning the crown
1) Slowly turn the crown clockwise (in the 12 o’clock direction) to wind the mainspring.
2) Continue to turn the crown until the mainspring is sufficiently wound. The second hand will start moving.
3) Set the time and date before putting the watch on your wrist.
2. How to set the time and date
• Check that the watch is operating, and then set the time and date.
• The watch is provided with a date function and is so designed that the date changes once every 24 hours.
The date changes around 12 o’clock midnight. If AM/PM is not properly set, the date will change around 12 o’clock noon.
1) Pull out the crown to the first click. (The second hand continues moving and the accuracy of the watch is unimpaired.)
2) The date can be set by turning the crown counterclockwise. Turn it until the previous day’s date appears.
Ex.) If today is the 6th of the month, first set the date to ”5” by turning the crown counterclockwise.
3) Pull out the crown to the second click when the second hand is at the 12 o’clock position.
(The second hand stops on the spot.)
Turn the crown to advance the hands until the date changes to the next.
The time is now set for the a.m. period. Advance the hands to set the correct time.
4) Push the crown back in to the normal position in accordance with a time signal.
CAUTION
• Do not set the date between 10:00 p.m. and 1:00 a.m.
If you do, the date may not change properly / it may cause a malfunction.
• The mechanism of mechanical watches is different from that of quartz watches.
When setting the time, be sure to turn back the minute hand a little behind
the desired time and then advance it to the exact time.
