You don't count the pulses, you measure the separation between the pulses.
Just like with the 1PPS output on your C-Beam.

In the United States we can buy analog quarts watches from Wal-Mart for under 15

and
buying one is the luck of the draw.  They can be as bad as 1 minute a month and 
they
always seem to be gaining.  Right now I have one that gains about 2 seconds a 
month.
I fully intend to see if it is possible to replace the battery when it runs 
down.
Counting motor pulses seems to be a little impractical because it would take 12 
days
to get to 1e6 accuracy.
