TECHNICAL GUIDE

Cal. 5J32A

Checking procedure

1.Adjust the time of the watch to a base time indicated by another watch.

2.Pull out the crown to the first click and push it back in to the normal position within one second. The manual power save function is activated, and the second hand stops moving.

Notes:

*Take care not to pull out the crown all the way to the second click.

*If this happens by mistake, resume the checking procedure from step “1”.

3.Leave the watch untouched for more than one minute, making sure that the power save function is in operation.

Normal position

First click

(Pull out the crown and push it back within one second.)

4.Swing the watch continuously for 2 to 3 seconds. The watch detects the generation of electricity, and the hands move to indicate the current time.

5.If the time indicated by the watch is identical with the base time used in step “1”, the manual power save and time relay functions are normal.

Note: If the power save function has been in operation for a long term before the time relay function is activated, the time indicated by the watch and the base time may differ slightly though the watch is normal. This is because the two watches are different in time accuracy and different amounts of time loss or gain have accumulated during that time.

IV. TROUBLESHOOTING GUIDE

The following are the tips on repairing Cal. 5J32A, which you will find helpful in working on the watch.

Important functions characteristic of Cal. 5J32A

1)The power save function is activated after the watch is left untouched for approximately 72 hours.

2)The manual power save function is activated by pulling out the crown to the first click and pushing it in to the normal position within one second.

3)While the second hand is moving at two-second intervals, the power save function cannot be activated either automatically or manually.

4)If the crown is pulled out to the second click while the power save function is in operation, the time computed by the built-in IC will be canceled, thus disabling the time relay function.

5)The built-in IC does not compute the date, and the time relay function will not adjust the date. If the power save function has been active for more than one day before the time relay function is activated, it is necessary to adjust the date to the current date.

6)The accuracy of the time computed by the built-in IC while the power save function is in operation is equivalent to that of conventional quartz watches. If the power save function has been active for a long term before the time relay function is activated, the time indicated by the hands may include a certain amount of time loss or gain that has accumulated during that time.

7)If the power reserve is depleted while the power save function is in operation, the time relay function may not be activated by swinging the watch, Instead, the second hand starts moving at two-second intervals.
