Suggestions for movement/motor for electronic pendulum clock

Hi,
First time post. I'm working on building a custom pendulum movement for a tall case clock I built. The "movement" is based on an Arduino processor driving a 1 second pendulum. The reason for the Arduino is to allow easy tweaking of impulse duration as well as driving a set of solenoids for sounding chimes. The problem I've run into is what to use for a "nice" motor for the hands. I currently have the circuit wired up to a cheap quartz movement, and it works, but I'm looking for something of higher quality. I hate the idea of putting a cheap plastic movement in my nice case!
There seem to be no higher quality quartz movements available; all are plastic junk that I can see.

I'm wondering if an old slave clock movement would work for this? Any other suggestions from the group?

thanks for any help or suggestions!

Dave

For slave clock you must obtain periodic pulses for coil. For example, in Europe most slave clocks work on alternate pulses, period is 1 minute. Voltages are 6, 12, 24, 48 or 60V but on most slaves you have possibility to chose one of several voltages. These clocks are without second hand. But, if you want good slave, look for some old movement. New movements are plastic and quality is not what it used to be.


Some old good quality movements:

So, beware...
