II.REMARKS ON DISASSEMBLING AND REASSEMBLING
For disassembling and reassembling, be sure to use the universal movement holder.
1Hands
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.
•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.
