Current consumption
For the whole movement
:
less than 1.20
µ
A
For the circuit block (4000 634) alone :
less than 0.28
µ
A
Remarks:
When the current consumption exceeds the standard value for the whole movement
but within the standard value range for the circuit block alone, the watch is generating
the driving pulse for compensating for the heavy load that may be applied to the gear
train, etc.
In this case, overhaul and clean the movement parts and then measure current consumption
for the whole movement again.
