While most quartz watches use cheaper stepping motors, there are also quartz watches which use synchronous motors, so the hands have a perfectly uniform and noiseless rotation movement.
I had some big wall clocks of this kind, and my father had such wrist watches.
The energy consumption of synchronous motors is lower, because they only have to overcome the friction forces, without having to also accelerate the mass of the hands.
