* 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)

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.

2. Turn the crown counterclockwise (the

six o’clock direction) to set the date to

the previous date.

Example:

When you wish to set the date to the sixth,

set to the fifth at this point.

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.

● 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.

1. Pull out the crown to the first click. (The second

hand continues moving.)
