Push the crown back into the normal position in accordance with a time signal.
2
Pull out the crown when the seconds
hand is at the 12 o’clock position.
(The seconds hand stops.)
3
Turn the crown counterclockwise (6
o’clock direction)
slowly to set the
time.
Set the minute hand about ten
minutes behind and then slowly
advance the minute hand to the
desired time.
Tips for more accurate time setting
To ensure effective operation of the Spring Drive mechanism, observe the following
instructions when you set the time.
1
Before setting the time, make sure to wind the mainspring sufficiently.
(Ensure that the power reserve indicator is showing a fully wound state.)
2
When starting to use a watch after it stops, wind the mainspring sufficiently. To set the
time after that, wait for
approximately 30 seconds after the seconds hand starts moving,
then pull the crown out to the first click.
3
The seconds hand will stop moving when the crown is pulled out to the first click. Do not
stop the movement of the seconds hand
for longer than 30 minutes. If the stoppage of the
seconds hand movement exceeds 30 minutes, push the crown back in, and wait for
approximately 30 seconds after the seconds hand restarts moving, and then set the time.

Minute repeater function
The minute repeater function audibly chimes the time with two different sounds, a low-tone
gong and a high-tone gong.
The number of times the low-tone gong is struck represents the hour, and the sequence of
low-tone and high-tone gongs represents the 10-minute intervals after the last hour, and the
number of times the high-tone gong is struck represents the minute.
While most minute repeaters use a
sequence of low-tone and high-tone
gongs for quarter hours, the minute
repeater of this watch has a decimal
system, which makes its time
announcement easily understood.
Hour
(a low-tone
gong)
10-minute interval
(a sequence of high-tone
and low-tone gongs)
Minute
(a high-tone
gong)
At four thirty-five
* Please note that the musical notes above are only an image of the gong sounds, and do
not represent the actual pitch or intervals of the sound you will hear.
