Why aren't computer clocks as accurate as cheap quartz watches?

Hi!
I've often wondered the same thing...also why a $9 alarm clock will have
provision for battery backup, but $200 VCR (back when VCRs were $200)
needed to be rweset with each blip in the mains voltage.
Hmmm...not all of them do. I've got a Panasonic VCR that will hold the
time for a couple of hours after a power failure and a Sony that seems
to be good for a few days. (Of course, both are 'mid-range' machines
and the Sony might qualify as lower high end equipment.)
I also have a Panasonic time-lapse VCR that has a NiCad battery in it.
I know it will the clock for at least two weeks. The manual says it
could last for a month.

I wanted to add, my alarm clock has a nicad battery backup, which
is why I bought it. Changing batteries is rediculous and expensive.
Why take the time and expense of changing batteries when a built
in nicad is all you need. I have also seen various VCR's that seem
to hold time for a certain period.
