Actually, you're quite right. The Custom Built "Accutron AstroView" is a concept watch represented as "The watch that Bulova should have built."I've seen that "factory" spaceview astronaut on a repair guy's webpage and asked him if he had more -- he said he spent a large amount of time making the dial in that picture from an astronaut dial, and wouldn't be making more.
That is a conversion that a guy is doing out of his shop. That was never offered for sale by BulovaBelieve it or not, there apparently was an Astronaut Spaceview made, but the watch for sale on Ebay is not one.
Here is a photo of what it looks like:
It also appears to be a GMT model.
