Requests and cautions regarding this watch
(Mechanical watch with automatic winding function)
• Although the mainspring will be wound automatically when the watch is worn on
the wrist, the mainspring will wind down after about 2 days and the watch will stop
if it is removed from the wrist.
• Make sure to adequately wind the mainspring before setting the time (hour and
minute hands).
• If the time is set without the mainspring being adequately wound, the second hand
will oscillate back and forth 2-3 seconds.
There are two ways to wind the mainspring: winding by turning the crown to the
right by hand, and winding by shaking the watch gently. The second hand may
rarely oscillate back and forth if the mainspring has been wound by shaking the
watch to the side with excessive force.
However, this has no effect on the functions or performance of the watch.
