20 year Pulse Motor. 2.86 Micro amp draw EZ spin type motor

This motor should run for at least 20 years.
It is far easier to make than my other Devices that will run for Centuries.
This Motor is a replication of an EZ Spin type motor by Theodore Pali.
He refined the motor.
Here are the specifics I used to calculate the amp draw. Using 50 ms time base signal is 3.5 divisions 3.550 150MS per pulse 154 rpm2.56 rps Pulses 2.56 times per second 2.56150384 there are 1000ms in one second. It is on 38.4 of the time 7.3842.68 Micro amps Each pulse is 7 Micro amps If I have calculated incorrectly please let me know.
I am not a math guy. 2.68 Micro amp draw will run for far longer than the batteries will last.
Eveready says that the battery will last 20 years in storage.
If they are correct the batteries will die long before they are drained.
AAA batteries are 1200 ma.
The drain of 2.86 micro amp should allow the battery to run for 45 years.
Since it is not likely that they will last much beyond 20 years.
I think that 20 years is a good bet. Here is the circuit design
