Band adjustment
We recommend seeking the assistance of an experienced watch technician
for sizing of your watch. If adjustment is not done correctly, the bracelet may
unexpectedly become detached leading to loss of your watch or injury (excluding
products containing the band adjustment tool).
Consult an authorized service center.
Protective stickers
Be sure to remove any protective stickers that may be on your watch (case back,
band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between
the protective stickers and the parts, which may result in a skin rash and/or
corrosion of the metal parts.

This is an automatic mechanical watch powered by a spring.
When wearing the watch, your arm’s movement rotates the oscillating weight to
wind the mainspring automatically.
• When your arm’s movement is small and/or a few, winding will become
insufficient. We recommend to wear the watch as long as possible or wind the
mainspring manually in such cases.
• Duration of movement after the mainspring is wound fully may differ depending
on models. For details, see the next page or "Specifications" (→ page
34
).

About mechanical watches
The accuracy of a mechanical watch in this instruction manual is static accuracy
at normal temperatures. Accuracy of a mechanical watch may not be kept within a
normal accuracy range due to using conditions such as below.
Winding amount
of the mainspring
A mechanical watch keeps its accuracy best when its mainspring is
sufficiently wound.
Posture of the
watch
Accuracy of a mechanical watch varies affected by gravity. The
accuracy varies as the result that the watch may take various attitude
while worn and gravitate to a different direction every moment.
Temperature
Metal parts are used for the part for keeping accuracy in a
mechanical watch. The accuracy varies affected by their thermal
expansion and contraction and change of characteristics as a spring.
Magnetism
Metal parts are used in a mechanical watch. Magnetism affects them
and accuracy of the watch in consequence. Do not bring it close to
things which have or generate strong magnetism.
Impact and others
Strong shocks and continuous vibration may also affect the accuracy.
