TECHNICAL GUIDE Cal. 6A32A
1. How to pull out the winding stem
With the crown at the normal position, using a tool
such as a pair of tweezers, press down the
designated area indicated by “PUSH” (as shown in
the illustration on the right) of the setting lever. And
then, pull out the winding stem to which the crown
is attached.
DISASSEMBLY
2. How to remove the hands
Reassemble the winding stem. Turn the hour, minute and second hands to align them pointing in the
same direction, and then remove them all together.
When using a tool such as a hand remover, exercise care so as not to damage the calendar frame or the
dial with the tool during the hand removing process. Align the hands together at a position where you
can avoid touching the calendar frame with the tool, in consideration of the orientation of the calendar
frame on the dial.
To prevent damage to the surface of the hands and dial, slip a thin plastic sheet between the dial and
remover.
3. How to remove the dial
From the lateral side at the foot positions of the dial
(indicated in the illustration on the right), insert the
tip of a driver or tweezers into the gap between the
lower surface of the dial and main plate to gradually
lift up the dial and remove it.
While doing this, make sure to lift the dial up
gradually one side after another. Lifting the dial up
only from one side may break the foot of the dial.
For disassembly and reassembly, make sure to use the all-purpose
movement holder.
