Unlike conventional movements, the date dial guard is not fixed with screws. It is set to the main plate with
three protrusions, which are caught under the main plate by turning the guard. Then, it is fixed by two guide
pins.

same way as described above, and then move it
counterclockwise until it mounts on the guide pin.
