Thank you for your purchase of this Citizen watch.
Before using the watch, read this instruction manual carefully to ensure
correct use.
After reading the manual, store it in a safe place for future reference.
Be sure to visit the Citizen website at http://www.citizenwatch-global.com/ .
Here you will find a variety of information such as electronic setting guides,
answers to frequently asked questions, Eco-Drive recharging information and
more.
To check the movement number
A case number—4 alphanumeric characters and 6 or
more alphanumeric characters—is engraved on the
case back. (Figure on the right)
The first 4 characters of the case number represent
the movement number of the watch. In the example
on the right, “
” is the movement number.
Engraving position example
The engraving position may
differ depending on watch
model.

Characteristics of Mechanical watches
About time accuracy of mechanical watches
The time accuracy described on this instruction manual is the static accuracy
at normal temperature. The accuracy of mechanical watches may get out of the
described range depending on the following three usage conditions or other
reasons.
• Winding amount of the mainspring
• Attitude
• Usage environment (temperature, magnetism, impact, etc.)
Winding amount of the mainspring
Mechanical watches keep accuracy most stably when the mainspring is sufficiently
wound.
Attitude
Accuracy of mechanical watches varies affected by gravity. The accuracy varies
as the result that may take various attitude while worn and gravitate to a different
direction every moment.

Characteristics of Mechanical watches
Usage environment (temperature, magnetism, impact, etc.)
• Metal parts are used for the part for keeping accuracy in mechanical watch. The
accuracy varies affected by their thermal expansion and contraction.
• Metal parts are used in mechanical watches. Magnetism affects them and
accuracy of the watches in consequence. Do not bring them close to things which
have or generate strong magnetism.
• Strong shocks may also affect the accuracy.
Maintenance
Mechanical watches may become inaccurate due to insufficient lubrication or worn
parts. Have the watch disassembled and cleaned (overhaul) every 2-3 years (charge
basis). It may be difficult to restore the watch from degradation after long-term use
to its initial performance even after repairs.

Characteristics of Mechanical watches
Requests and cautions regarding this watch
• 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 for the automatic winding watch, 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.

Before using
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.
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.

Before using
How to use a specially designed crown
Some models are equipped with a specially designed crown to prevent accidental
operation.
Screw down crown
Unlock the crown prior to operate your watch.
Unlock Lock
Push the crown in to the
case. With gentle pressure
towards the case, rotate the
crown clockwise to secure
it to the case. Be sure to
tighten firmly.
Screw down
crown
Rotate the crown
counterclockwise until
it releases from the
case.
