Frozen motionblur for an effect

[Lucavfx]

Hi, I would like to create a frozen motion blur effect where the geometry moves very slowly, but a fast-moving version creates smears and long-shutter blur in space, similarly to the watch example below.

I would like the motion blur smear to feel optical in nature, so it would be bendy and natural, similar to how deformation blur with high-geo samples works.

How do you achieve natural-looking curved motionblur with point or volume data rather than deformation blur?

Thanks

Maybe animate the geo or volume on subframes using simple modulo expression?

(hate to put pighead in such a vulnerable situation)
