● HOW TO SET THE TIME AND DATE
When setting the date and time, ensure that the watch is working: the main
spring is sufficiently wound.

2. Wind the mainspring until the power reserve
indicator shows a full-wound state. The second
hand will start moving.
* To check the winding state of the mainspring,
refer to "HOW TO READ THE POWER RESERVE
INDICATOR " on page 14.
* 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.
1. Pull out the crown to the first click. (The second
hand continues moving.)

Example:
When you wish to set the date to the sixth,
set to the fifth at this point.
2. Turn the crown counterclockwise (the
six o'clock direction) to set the date to
the previous date.
* Do not change the date while the watch
hands show any time between 9:00 PM
and 1:00 AM. Date setting during this
time period may prevent the date from
changing correctly on the following day.
To avoid this, pull out the crown to the
second click, and turn it counterclock-
wise (the six o'clock direction) to
temporarily advance the hands to show
any time after 1:00 AM. Then push the
crown back to the first click to set the
date.
