TECHNICAL GUIDE Cal. 6A32A

1. How to pull out the winding stem

With the crown at the normal position, using a toolsuch as a pair of tweezers, press down thedesignated area indicated by “PUSH” (as shown inthe illustration on the right) of the setting lever. Andthen, pull out the winding stem to which the crownis attached.

DISASSEMBLY

2. How to remove the hands

Reassemble the winding stem. Turn the hour, minute and second hands to align them pointing in thesame 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 thedial with the tool during the hand removing process. Align the hands together at a position where youcan avoid touching the calendar frame with the tool, in consideration of the orientation of the calendarframe on the dial.

To prevent damage to the surface of the hands and dial, slip a thin plastic sheet between the dial andremover.

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 thetip of a driver or tweezers into the gap between thelower surface of the dial and main plate to graduallylift up the dial and remove it.

While doing this, make sure to lift the dial upgradually one side after another. Lifting the dial uponly from one side may break the foot of the dial.

For disassembly and reassembly, make sure to use the all-purpose

movement holder.

<Reassembly>

1. Turn the date dial guard clockwise until it is halfwayengaged with the date dial guard fixing guards atthe A, B and C positions each.

2. While further turning the date dial guard clockwise,press the date dial guard guide holes toward theguide pins of the main plate at the A and B positionsuntil the date dial guard fixing guards are completelyengaged with the main plate.

<Disassembly>

1. Using a pair of tweezers, lift the A position of thedate dial guard to disengage the date dial guardguide hole and the guide pin of the main plate.Turn the date dial guard counterclockwise until itoverrides the guide pins of the main plate.

2. Using a pair of tweezers, lift the B position of thedate dial guard to disengage the date dial guardguide hole and the guide pin of the main plate.Turn the date dial guard counterclockwise until itoverrides the guide pins of the main plate.

3. Turn the date dial guard counterclockwise until it isdisengaged from the date dial guard fixing guardsof the main plate. And then remove the date dialguard.

● Coil block resistance

1.28 - 1.48kW

[Measuring the coil block resistance]

1. Measure the resistance with the coil block installed on the main plate.

2. Apply the red and black probes of the tester to the patterns of the coil lead terminal. While doing so, takecare not to touch the end portion of the coil lead terminal, as this may break the coil wire.

● Current consumption

For the whole movement: less than 1.61mA

For the circuit block alone: less than 0.3 mA

[Measuring the current consumption for the whole movement]

1. Apply the red probe of the tester to the pattern of the positive (+) terminal of the circuit block and the blackprobe of the tester to the pattern of the negative (-) terminal of the coil block.

2. After connecting the tester, wait for approximately one minute until the current consumption becomesstable. When the current consumption shows stable measurements, read the measurement.

[Measuring the current consumption for the circuit block alone]

1. Connect the tester to the positive (+) and negative (-) input terminals of the circuit block. Wait forapproximately one minute until the current consumption becomes stable. When the currency consumptionshows stable measurements, read the measurement.

* Light may increase the current consumption, resulting in an inaccurate measurement. Protect the movement fromlight with a black cloth or similar, and take a measurement again.

VALUE CHECKING

CAUTION

When the current consumption for the whole movement exceeds the standard value, measure thecurrent consumption for the circuit block alone. If the current consumption for the circuit block alone iswithin the standard value range, a driving pulse may be generated. In that case, overhaul and clean themovement parts, and then measure the current consumption for the whole movement again.

● Checking the accuracy

In order to check the accuracy, set the gate time of the quartz tester to 10 seconds, and measure theaccuracy with the crown at the original position.

How to set the hour hand

1. Pull out the crown to the second click position and turn itclockwise to advance the hour hand. Stop the hour hand at themoment the date changes.

2. Set the hour hand pointing to the 12 o'clock position.

• Press it down to the surface of the hour wheel.

• Exercise care so as not to damage the arbors of the minutewheel and fourth wheel.

3. Make sure that there is no friction between the hour hand and thedial. Adjust the height of the hour hand if necessary.


Reassembling the exterior parts (1)

Set the battery.

1. Slide the battery in the direction shown by the arrow in the illustration (with the positive side facing up.)

2. Attach the clip to the battery holder.

* If the clip of the battery holder is attached to the main plate, take it off.

1. Check the two positions of the slots on the mainplate and the position of the calendar frame of thedial. Place the dial temporarily.

2. Align the dial properly and firmly press it down toset it.


Set the dial.

How to set the minute hand

1. Temporarily set the minute hand pointing to the 12 o’clockposition.

2. Turn the crown counterclockwise at the second click position tomove the minute hand backward passing the 9 o’clock position,and then turn the crown clockwise to move the minute handforward in order to check the timing when the date changes. Ina case that the date changes at a time out of the target time ofthe date change, remove the minute hand and mount it again.

3. Firmly press the minute hand down to set it.

• Press the minute hand down to the surface of the centerwheel, but be careful not to press it excessively.

• Exercise care so as not to damage the arbor of the fourthwheel.

• Target time of the date change: between 23:00 and 01:00

4. Make sure that there is no friction between the minute hand andthe hour hand, between the minute hand and the markers on thedial, and between the minute hand and the calendar frame.Adjust the height of the minute hand if necessary.

How to set the second hand

1. Align the second hand so as to position the tip at the center of thewidth of the graduation marker, and slightly press it down to setit temporarily.

2. Push the crown back to the original position and check the sweepof the second hand.

• In a case that the second hand movement shows a largedeviation from the graduation, remove the second hand andset it again.

3. After confirming that the second hand sweeps along with thegraduation, pull out the crown to the second click position to stopthe second hand movement, and then firmly press it down to setit.

• Press the second hand down adequately without pushing itinsufficiently or excessively.

Hand installation check ups

1. Ensure that there is an adequate clearance between the dial andthe hour hand, between the hour hand and the minute hand, andbetween the minute hand and the second hand. Also check thatthe second hand is slightly curved upward. Make sure that thereis no friction. Adjust the position of the height of the hands ifnecessary.
