• How to remove the date dial guard in replacing the date dial
(with the parts on the movement side installed)
Be sure to use the movement holder 4F8F-C for
exclusive use for replacing the date dial.
Unlike conventional movements, the date dial guard is not fixed with screws. It is set to the main plate
with the three protrusions, which are caught under the main plate by turning the guard. Then, it is fixed
by the two guide pins.
B portion
• How to install
1. Put the date dial guard on the main plate so that
the A and B portions are over the guide pins, as
shown in the illustrations at right.
2. Move protrusion D of the date dial guard in the
counterclockwise direction so that it is caught
under the main plate.
3. Slightly move protrusions C and E in the
counterclockwise direction alternately to set them
under the main plate. While doing so, set the A
and B portions of the date dial guard to the guide
pins.
Note: Take care not to press down the ultrasonic
rotor pinion while installing the date dial guard.
