Before Using - Citizen 8203 User Manual

3. Before Using

This watch is a mechanical watch (self-winding). Before using, disengage the screw
down locking crown and turn it to the right by hand to wind the watch mainspring.
When the mainspring is in the fully wound state (sufficiently wound), the watch will
continue to run for about 40 hours. In order to ensure that the watch continuously
provides a stable time display, always wear the watch on your wrist to keep the
mainspring adequately wound. If the watch is only worn for short periods of time,
wind the mainspring manually by turning the crown by hand.

When operating the crown, first turn it to the
left to disengage the screw lock. Once you have

that the screw lock is securely engaged.

[General Reference for Winding Mainspring when Completely Unwound]
• After first loosening the screw down locking crown, turn it to the right
about 40 revolutions to fully wind the mainspring.
Keep the mainspring adequately wound either by turning the crown by hand or
by wearing the watch on your wrist for at least three hours each day.
If the watch is only worn for short periods of time, turn the crown by
hand to keep the mainspring fully wound. Since this watch employs a
slip mechanism that automatically disengages the mainspring when fully
wound, it cannot be over-wound.
