◆HOW TO SET THE TIME
1Pull out the crown to the second click when the small
second hand is at the 12 o’clock position.
The small second hand stops on the spot.
2Turn the crown to set the time.
This watch has a 24-hour hand, which is linked to
the operation of the watch, so check whether the
24-hour hand indicates AM or PM when turning the
hour and minute hands to set the time.
To set the time accurately, advance the minute hand
four or five minutes ahead of the correct time, then
move it back to the correct time.
3Press the crown in at the same time as the time
signal. The watch starts to run.
◆HOW TO SET THE DATE

3After all the adjustments are completed, push the
crown back in to the normal position.
• Date correction at the end of the month
Date correction is necessary on months with 30 days or less, so on the first
day of the next month, adjust the date to the first.
WARNING
Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, the date may not
change properly. If it is necessary to set the date during that time period, first change
the time to any time outside it, set the date and then, reset the correct time.
◆HOW TO USE THE CHRONOGRAPH
Chronograph measurement is in units of one second, up to a maximum duration
of 59 minutes and 59 seconds.

◆OPERATING THE TACHYMETER
The tachymeter is a function that measures the time required to pass through a
certain distance (1 km) and find the average hourly speed. It can also find perfor-
mance per unit time (one hour).
* The measurement time of the tachymeter is limited to one minute or less. Please
note that if the measurement time exceeds one minute, it will not be possible
to read the average hourly speed or performance per hour.
Button A
1Press button Asimultaneously with the start (or with the
start of product fabrication).
Button A
2Press button Asimultaneously with reaching the 1 km
point (or with the end of product fabrication).

3Read the number on the tachymeter scale indicated by
the chronograph second hand.
(In this example, the tachymeter number is 80, so the
average hourly speed is 80km/hr, or the hourly production
is 80 pieces.)
* Depending on the product, the tachymeter scale may be printed on the bezel
or on the face. Check the watch you purchased and then refer to the operation
method.
◆ NOTES ON THE SCREW CROWN
■Models with screw down crown
• If your watch has a screw down crown, it is necessary to unlock the crown by

* It is recommendable that you use the watch correctly following the mentioned
scope of usage after ascertaining water-resistance precautions marked on the
dial face of the watch or on the back of the watchcase.
CAUTION
1Keep the crown pushed in at all times (in the normal position) while using the
watch. If the crown is the screwed-down type, check that it is securely screwed
down.
2Do not operate the crown or buttons underwater, or while the watch is wet.
Water may enter the interior of the watch and defeat the water resistance.
3If your watch is non-water resistant, beware of splashes of water (during face
washing, rain, etc.) and sweat. If the watch becomes wet from water or sweat,
wipe the moisture off with a dry, soft cloth.
4Even with an improved water resistant watch for everyday use, avoid directing
strong jets of mains water onto the watch. Water pressure above the limit can
apply, which may defeat the water resistance.
5With an improved water resistant watch for everyday use, rinse sea water off
the case after exposure, then wipe it thoroughly to avoid corrosion and other
effects.
6The durability of leather bands may be adversely affected by wetting, due to the
nature of the material, and they may lose color or peel where glued. Especially
when you use the watch in water, change to another type of band first (one
made of metal or rubber).
7The interior of the watch contains some amount of moisture, which may cause
fogging on the inside of the glass when the outside air is cooler than the internal
temperature of the watch. If the fogging is temporary it causes no harm inside
the watch, but if prolonged, or if water enters the watch, consult your place of
purchase and do not leave the problem untreated.

(2) Shock
1Be sure to take the watch off your wrist when you engage in
strenuous sports, whereas playing such light sports as golf,
etc., will not adversely influence the watch.
2Avoid a violent shock such as dropping the watch on the
floor.
(3) Magnetism
1If the watch is left at a place near strong magnetism for an extended period,
the component parts can get magnetized, resulting in a failure. Be careful.
2The watch can temporarily gain or lose time when exposed to magnetism, but
it functions with original precision when it is put away from the magnetism. In
this case, correct the time.
(4) Vibration
The watch can lose time temporarily when it is exposed to
strong vibration while riding motorcycles or using jackham-
mers, chain saws, etc.
(5) Temperature
1In the environment below and above the normal temperatures <5°C-35°C>,
the watch may malfunction and stop.
2If the watch is left unworn, it may lose accuracy to some extent.
(6) Chemicals, Gasses, etc.
Utmost caution must be exercised for contacts with gasses, mercury, chemicals
(thinner, gasoline, various solvents, detergents containing such components,
adhesives, paints, drugs, perfume, cosmetics, etc.), and so forth. Such contacts
may cause the discoloration of a watchcase, a watchband, and a dial face. The
discoloration, deformation, and damage of various resin-based component parts
may also occur.
