Problems Possible causes Methods of repair and checking
The current consumption for
the circuit block alone exceeds
the standard value.
1) The light from outside the
movement is affecting the
measurement.
2) When the measurement is
made, the IC is still in the
quick start mode. (When the
current consumption
measures about 200μA, it is
likely that the IC is in the quick
start mode.)
3) The IC is out of order.
1) Shut out the light, and make the
measurement again.
2) Switch the IC to the normal mode,
and make the measurement again.
3) Replace the circuit block.
Swinging the watch while the
power save function is active
will not activate the time relay
function. (Swinging the watch
starts the second hand
moving at two-second
intervals.)
The energy stored in the
rechargeable battery has been
depleted while the power save
function is in operation.
Swing the watch until the second
hand moves at one-second
intervals, and activate the power
save function manually to check if
the time relay function can be
activated.
Swinging the watch while the
power save function is active
will not activate the time relay
function. (Swinging the watch
will not start the second hand
moving at all.)
There is electric leakage inside
the hour and minute coil
block.
Check for leakage of the hour and
minute coil block. Replace the part
if leakage is detected.
After the time relay function is
activated, the hands do not
make the quick movement
smoothly, or the hands
indicate a time that differs
greatly from the correct time.
There is electric leakage inside
the hour and minute coil
block.
Check for leakage of the hour and
minute coil block. Replace the part
if leakage is detected.
