Frequently Asked Questions
Our support team searches for useful product information and answers to frequently asked questions. If you find an inaccuracy in our frequently asked questions, please let us know by using our contact form.
My mechanical watch runs fast, what can I do? Verified
This might be caused by exposure to a magnetic field. It can be solved by a demagnetisation process performed by a professional watchmaker.
This was helpful (662)
A battery in my device is oxidized, can I still safely use it? Verified
Ja, the device can still be safely used. Firstly, remove the oxidizd battery. Never use bare hands to do this. Then clean the battery compartment with a cotton swab dipped in vinegar or lemon juice. Let it dry and insert new batteries.
This was helpful (653)
What do AM and PM stand for? Verified
AM stands for Ante Meridiem and indicates that the time is before midday. PM stands for Post Meridiem and indicates that the time is past midday.
This was helpful (571)
What is a ‘Chronograph’? Verified
A ‘Chronograph’ is literally a ‘writer of time’. The term is used to describe clocks and watches that tell the time of day as well as measure a certain period of time, like a stopwatch.
This was helpful (518)
What is GMT? Verified
GMT stands for Greenwich Mean Time (sometimes called UTC, standing for Coordinated Universal Time). It is the time for the longitude 0, that passes through Greenwich near London.
This was helpful (350)
What is a quartz movement? Verified
Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.
This was helpful (350)
There is moisture on the inside of the glass of my Casio watch, what should I do? Verified
Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.

Important!
● This watch is not a special-purpose
measuring instrument. Measurement
function readings are intended for
general reference only.
● Whenever using the Digital Compass
of this watch for serious trekking,
mountain climbing, or other activities,
be sure to always take along another
compass to confirm readings. If the
readings produced by the Digital
Compass of this watch are different
from those of the other compass,
perform figure 8 calibration or 2-point
calibration of the watch compass to
ensure better accuracy.
ー Compass readings and calibration
will not be possible if the watch is in
the vicinity of a permanent magnet
(magnetic accessory, etc.), metal
objects, high-voltage wires, aerial
wires, or electrical household
appliances (TV, computer,
cellphone, etc.)
l Digital Compass
● The watch’s Altimeter Mode calculates
and displays relative altitude based on
barometric pressure readings
produced by its pressure sensor.
Because of this, altitude values
displayed by the watch may be
different from your actual elevation
and/or sea level elevation indicated for
the area where you are located.
Regular calibration in accordance with
the local altitude (elevation)
indications is recommended.

Digital Compass Reading
Precautions
Location During Use
Taking readings near sources of strong
magnetism can cause reading error. Keep the
watch away from the following types of items.
Permanent magnets (magnetic accessories,
etc.), metal objects, high-voltage wires, aerial
wires, electrical household appliances (TVs,
computers, cellphones, etc.)
● Note that correct direction readings are not
possible indoors, especially inside of
reinforced concrete structures.
● Accurate direction readings are not
possible in motor vehicles, on boats, on
aircraft, etc.
Storage Location
Exposure of the watch to magnetism can
affect the accuracy of digital compass
readings. Keep the watch away from the types
of items below.
Permanent magnets (magnetic accessories,
etc.), metal objects, electrical household
appliances(TVs,computers,cellphones,etc.)
Altitude Measurement
The watch takes altitude readings and
displays results based on air pressure
measurements taken by a built-in pressure
sensor.
Important!
● The altitude readings displayed by the
watch are relative values that are
calculated based on barometric
pressure measured by the watch’s
pressure sensor. This means that
barometric pressure changes due to
weather can cause altitude readings
taken at the same location to be
different. Also note that the value
displayed by the watch may be
different from the actual elevation and/
or sea level elevation indicated for the
area where you are located. When
using the watch’s altimeter while
mountain climbing, it is recommended
that you regularly calibrate its readings
in accordance with local altitude
(elevation) indications.
l Calibrating Altitude Readings
(Offset)
● The altitude correction value and
barometric pressure changes may
result in display of a negative value.
● Check the information below to find out

Pedometer
You can use the pedometer to keep track of
your step count while walking, engaging in
your normal daily activities, etc.
Counting Steps
If you are wearing the watch correctly, the
pedometer will count your steps as you walk
or engage in your normal daily activities.
Important!
● Since this watch’s pedometer is a
wrist-worn device, it may detect non-
step movements and count them as
steps. Also, abnormal arm movements
while walking may cause a miss count
of steps.
● Getting Ready
To enable the most accurate step count, wear
the watch with the face on the outside of your
wrist and tighten the band securely. A loose
band may make it impossible to obtain correct
measurement.
NO
YES
● Counting Steps
The pedometer will start counting your steps
when you start walking.
● To check the step count
Displaying the step count screen.
l Mode Overview
Note
● The step count can show a value up to
999,999 steps. If the step count
exceeds 999,999, the maximum value
(999,999) remains on the display.
● To prevent miscounts, the displayed
count does not increase for about 10
seconds after you start walking. After
you have been walking for about 10
seconds, the correct count appears,
including the steps you took during the
previous 10 seconds.
● The step count is reset to zero at
midnight each day.
● To save power, step counting stops
automatically if you take off the watch
(no detectable watch movement) and
you do not perform any operation for
two or three minutes.
Causes of Incorrect Step
Count
Any of the conditions below may make proper
counting impossible.
● Walking while wearing slippers, sandals, or
other footwear that encourages a shuffling
gait
● Walking on tile, carpeting, snow, or other
surface that causes a shuffling gait
● Irregular walking (in a crowded location, in
a line where walking stops and starts at
short intervals, etc.)
● Extremely slow walking or extremely fast
running
● Pushing a shopping cart or baby stroller
● In a location where there is a lot of vibration,
or riding on a bicycle or in a vehicle
● Frequent movement of the hand or arm
(clapping, fanning movement, etc.)
● Walking while holding hands, walking with
a cane or stick, or engaging in any other
movement in which your hand and leg
movements are not coordinated with each
other
● Normal daily non-walking activities
(cleaning, etc.)
● Wearing the watch on your dominant hand
● Walking for 10 seconds or less
