For anyone who doesn’t know, a clock movement is the mechanism that causes the hands of an analog clock to move around the clock face. The “with pendulum” part means that it also swings a weight back and forth to act as a fancy second hand:

Now, there exist clock movements that are “smart” and are network enabled to adjust the time automatically. I’m also okay with an atomic movement. The idea is to adjust the clock twice a year for DST. However, I am having a difficult time (no pun intended) finding a smart/atomic movement that also supports a decorative pendulum.

I was hoping to enlist y’all’s help to see if one exists and where I might find it.

Edit: add comments about atomic clock movements.
