Ⅱ. REMARKS ON DISASSEMBLING AND REASSEMBLING
①Hands
・How to install
Place the movement directly on a flat metal plate or the like
to install the hands.
②Date dial guard
The date dial guard has three protrusions to be caught under the main plate, and it is also fixed
by two guide pins.
・How to remove
Lightly lift the A portion of the date dial guard with
tweezers to release it from the guide pin, and then
move it in the clockwise direction until it gets off
the guide pin.
Release the B portion of the date dial guard in the
same way as described above, and then move it in
the clockwise direction until gets off the guide pin.
Check that all the three protrusions of the date dial
guard have come off from the main plate, and then
remove the date dial guard.

・How to install
Put the date dial guard on the main plate so that
the A and B portion are over the guide pins,
as shown in the illustration at right.
Move the protrusion D of the date dial guard in the
counterclockwise direction so that it is caught
under the main plate.
Slightly move the protrusions C and E in the
counterclockwise direction alternately to set
them under the main plate. Then, set the
A and B portions of the date dial guard to
the guide pins.
Check that the date dial guard is fixed
securely to the main plate.
③Battery
・How to install battery
Insert the battery aslant in the direction shown by the arrow.
Check the battery connection (+) securely touches the side
face of the battery.

④Battery connection (+)
・How to install
Have the hook portions (3 places) catch the main plate (Fig.1 & Fig.2).
In disassembling and reassembling, take care not to deform the hook portion.
After installing the battery connection (+), check that the three hook portions securely catch the main plate.

Setting position of the First date indicator & Second date indicator.
・How to set First date indicator & Second date indicator in position.
Note:
1. First date indicator setting.
When the First date indicator is set, the hole in First date indicator will merge with the hole in battery
compartment. It takes place at 1 o'clock position of main plate.
(Pull out the crown to first click and turn the crown to set First date indicator.)
2.Second date indicator position setting.
After the Second date indicator was set. Rotate the Second date indicator in clockwise by touching on its
surface lightly with finger. Until the Second date indicator hole overlap with the First date indicator hole
at 1 o'colock position. The position is set.
3.When the date indicators were set properly.
Abnormal date does not display.
For example ) <00> day <32> day <33> day <34> day …... <39> day
(NOTE)
First date indicator cannot turn Second date indicator at any places other than Fig 2.
If it is made to rotate by force, there is a possibility that parts may break.
