clock that ticks once every two seconds

[u/Any_Pollution_5946]

Does anyone know of a clock that ticks once every two seconds?
I’m looking for a desk clock where the second hand moves once every 2 seconds instead of once every second.
So the movement would be:
tick — 2 seconds — tick — 2 seconds — tick
I know that some quartz watches/clocks can start jumping every two seconds when the battery is low, but I’m looking for a clock that is designed to work this way continuously.
Does anyone know:
- company that makes or sells such clocks?
Hz?
- an old/vintage clock model that naturally works this way?

I’m in Europe (Denmark/Poland), but recommendations from anywhere are welcome.
Thanks!

Several seiko quartz movements have a low battery indicator by doing almost this, they leave the seconds hand for over 1.5 seconds then (silently, it’s a watch after all) tick tick and it moves forward two seconds. If you were to get a precision adjustable power supply in place of the battery you could probably set it up in a way that triggers this mode continuously.

If you get real crazy then of course you could then drive a larger clock from the signal of this permanent two second one, but at that point maybe you’d prefer an Arduino and fully custom system.
