It's not unusual for a quartz movement in what would classically be a "pendulum" clock to feature a fake pendulum that's not at all connected to the clock movement itself. Often there's just an electromagnet to give it an occasional kick to keep it moving. It may also, as you surmised, be driven by a simple motor without any (quartz) timer mechanism to keep it paced with the hands.

I didn't know I had a horologist in me until it fled, screaming, from the shop.

The other thing I have that seriously breaks my head is, coincidentally, another clock. It was painted by famous space artist David Hardy, and is a starscape with Earth in the middle (where the hands are fixed) and twelve Moons in a circle around it, in progressive phase, to mark the hours. But - aieeee! That means the Sun has to be in twelve different places at the same time, to provide the illumination?
