Today's battery operated quartz
movements are simply amazing!
They use common batteries which last for
a year or more
and are accurate to within 20 seconds a
month.
That's four minutes a year. These
movements
or motors can operate hands from
under a inch
to nearly 18 inches long. Many models or
even Made in America.
Imagine the possibilities. Small
compact size makes them easy to use
almost anywhere. Many models are just 2 1/8" square
and 5/8" inch thick. 
Using our UPS uninterrupted power
source
almost all of our movements can be made to
operate on
110-volt wall current with a battery backup
if the wall current is interrupted.  It's  the
best of both worlds.
Some quartz movements are available with
pendulums.
These pendulums have an even
natural swing but actually have no
affect on the timekeeping.
Most of our movements use the common
American "I" shift for installing the
clock hands.
This design is popular here in the US
but not widely used elsewhere. This
"I" shaft system uses a small nut to hold
the minute hand in place.
It's a much more secure system. It's not
hard to replace a clock movement
you just need to take some basic
measurements of your clock case.
The most important thing is to determine
the length of the hand shaft needed. You can
could do this by measuring how thick the
material is that the hand shift has to
go through.
The threaded bar the hand shaft
should come through the clock dial by a
1/16" to an 1/8"
so that an hex nut can
easily be tightened
to hold the movement in place. A long
shaft can be shimmed back in the clock
case with a few washers.
To short hand shaft simply will not
work.
Once you know the shaft length you need
for your clock
pick out the clock hands and you'll be
ready to create a new masterpiece
or bring an old one back to life. For
