for oil condition or damage due to water or sweat. After checking the watch,
adjustment and repair may be required.

time it may function improperly or stop operating.
Do not leave the watch in a place where it is subjected to strong magnetism or
static electricity.
・Do not leave the watch where there is strong vibration.
・Do not leave the watch in a dusty place.
・Do not expose the watch to gases or chemicals.

When the mainspring is fully wound, the crown can be turned further, or the
mainspring may wind without damaging the mainspring itself. The mainspring of the
watch employs a slipping attachment structure, a self-winding watch specific
mechanism, to prevent the mainspring from over winding.
●Remarks on the self-winding mechanism of the mainspring
・The correlation between the number of hours the watch is worn and
the winding state of the mainspring is provided below for your
reference. However, the winding state of the mainspring may vary
depending on actual use conditions, such as the number of hours you
wear the watch or the extent of your movement while wearing it. It is
recommended that you observe the power reserve indicator to check
the level of remaining power of your watch.
The mainspring of the watch becomes fully wound when it is worn for
twelve hours for three to five days.
In a case where you wear the watch for a short period of time each day, observe the
power reserve indicator to check the level of the remaining power. If necessary,
manually wind the mainspring.
62
■HOW TO READ THE POWER RESERVE INDICATOR
The power reserve indicator lets you know the winding state of the mainspring.
Before removing the watch from your wrist, observe the power reserve indicator to
check if the watch has stored enough power to keep running until the next time you
wear it. If necessary, wind the mainspring. (To prevent the watch from stopping, wind
the mainspring to store the excess power that will allow the watch to run for extra
time.)

RASH AND ALLERGY
Adjust the bracelet and band so that there will be a little clearance between the
bracelet or band and your wrist to avoid accumulation of perspiration.
If you are constitutionally predisposed to rash, the band may cause you to
develop a rash or an itch depending on your physical condition.
・The possible cause of the rash are as follows:
1. Allergy to metals or leathers
2. Rust, dust or perspiration on the watch or band
If you develop any skin reactions, take off the watch and consult a doctor
immediately.
CAUTION
64
■TO PRESERVE THE QUALITY OF YOUR WATCH
CARE OF YOUR WATCH
The case and bracelet touch the skin directly just as underwear. If they are left
dirty, the edge of a sleeve may be stained with rust of those who have a
delicate skin may have a rash.
After removing the watch from your wrist, wipe perspiration or moisture with a
soft cloth. This will prevent the watch from being soiled, adding to the life of
the gasket.
<LEATHER BAND>
When removing moisture from a leather band, do not rub the band with the
cloth as this may discolor it or reduce its gloss. Be sure to blot up the moisture
using a soft dry cloth.
<METAL BRACELET>
Clean the watch bracelet with a soft toothbrush dipped in water or soapy
water.
CAUTION
