The explanation here is only for the particular points of Cal.VJ12B /VJ14B
Ⅰ.STRUCTURE OF THE CIRCUIT BLOCK
Notes: Since the circuit block and coil block are made by one piece, in disassembling and
reassembling take care not to cut the coil line.

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

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
