That’s why the continuous motion ones are so sought after and pricy. The mechanical continuous motion watches are really marvelous feats of engineering

They're also (as far as I understand it) not actually continuous motion. They just have much smaller increments of movement than a single second.

It's still continuous, as even when fully ticking, it still goes from point a to b passing through all the in between points... well, up to planck length at least...

Ticking just makes the motion jerky/abrupt, not discontinuous/discreet...

Ooh, alright, you win this one, but only on a technicality. I won't mention the fact that liquid crystals are also in a constant state of motion while under power ;-)

> up to planck length at least...

Well, we actually do not know that...

It seems there are mechanisms with fully continuous motion, eg: https://www.grand-seiko.com/global-en/about/movement/springd...

Is it "fully continuous" if it has a discret electronic controller correcting it all the time?

The movement is still quantized if you look close enough.

Not in any discernible degree without at least an electron microscope...

Your eyes will quantize the display before the mechanism does.
