* 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 50 hours. However, when
the stopwatch is used continuously for a certain period, the watch may not operate
for as long as 50 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 8 hours a day. If the watch is used
without being worn on the wrist (if it is used on the desk like a clock, for example),
make sure to wind it up fully every day at a fixed time.
* If the watch has stopped with the mainspring unwound, winding the mainspring
with the crown will not start the watch immediately. This is because the mainspring
torque (force) is low at the beginning of its winding due to the characteristics of
mechanical watches. The small second hand starts to move when a certain degree
of strong torque is reached after the mainspring has been wound up. However,
swinging the watch from side to side to forcibly turn the balance can start the watch
sooner.

small second hand continues moving and
the accuracy of the watch is unimpaired.)
2. The date can be set by turning the crown
clockwise. Turn it until the previous day’s
date appears.
