I've done some googling and have yet to see one.

I've never heard of one.

Like Skypilot, I have never seen or heard of one. The closest would be the 218 skeleton view, I guess. The 214 movement is much more attractive in a Spaceview model.

There is this........

380462604912 on the bay.

Spaceview 21 Kinetic auto quartz. I think they were based on the same movement as the spaceview II which really wasn't a spaceview, it had a see through case back. Bulova tries every so many years to market based on the original spaceviews. This was the attempt from 2001

Yep, as said before, that one uses the Seiko Kinetic type of movement. A rotor spins with wrist movement to keep a capacitor charged. Not a battery, not a tuning fork and vastly overpriced, IMHO.
