TECHNICAL GUIDE
II. REMARKS ON DISASSEMBLING AND REASSEMBLING
Cal. 5J32A
For disassembling and reassembling, be sure to use the universal movement holder.
1 Hands
In case of conventional quartz movements, the hands should be installed immediately after the date
changes by turning the crown. Cal. 5J32A uses a new calendar mechanism that changes without
perceptible clicks, and therefore, the procedure below should be followed to install the hands.
4 Hour wheel guard spring
5 Date dial guard
Guide tube
Hour wheel
guard spring
“A” portion
Tube
Spring portion “B”
• How to install
1. Pull out the crown to the second click, and
turn it counterclockwise.
2. Check if the date numeral moves in the
calendar frame. When it starts to move,
turn the crown slowly, and stop turning it
when the numeral stops moving.
3. Install the hour hand exactly at the 12
o’clock position.
4. Install the minute and second hands in the
same manner as you would do for a
conventional quartz movement.
• Setting position
Refer to the illustration at right.
Note: Handle the hour wheel guard spring
carefully lest its spring portion should
be deformed.
· “A” portion in the illustration at right has
elasticity and is made tight in order to be set to
the guide tube. Make sure that “A” portion is
set securely in position.
· Hook the spring portion “B” of the date dial
guard to the tube as shown in the illustration
at right.
