Look into Mondaine wristwatches, they are patterned after these and they’re pretty neat if you’re looking for a kind of a statement watch
They are officially licensed and you can get stop-and-go versions as well.
Still remember when iPads used this clock face. I wish that was still the case.
The station clocks in Switzerland are synchronised by receiving an electrical impulse from a central master clock at each full minute, advancing the minute hand by one minute. The second hand is driven by an electrical motor independent of the master clock. It takes only about 58.5 seconds to circle the face; then the hand pauses briefly at the top of the clock. It starts a new rotation as soon as it receives the next minute impulse from the master clock.
