The 'Bowtie' is just a nickname for this case style and not an official model name.
As this watch is presented it's unfair to say it's a Spaceview, as it's missing a key component to be a Spaceview.....a correct crystal.
I agree with Jim, this looks like someone simply removed the dial in order to try and make a Spaceview.
We had an interesting discussion here about the 'potential' Spaceview in a bowtie case, which I tend to agree with. The linebooks I've looked at as well as Darold Hanson's 'Accutron Watches' book does not list any Spaceviews in this stye case.
I'm 99% confident in saying Bulova did not release a Spaceview in this case style.
