On the gen, the hour markers are white with a silver (or bmg/titanium) rim around the lume plots, the way you see in like the 799 or on the 682. As opposed to being just a solid marker the way you see 1616 (but on the 1616, they're blue).
In the pics in this thread, looks like the VSF version has just a solid white dot on the hour marker. Or maybe it looks like (in one Pic) it has a white rim around a white marker. Maybe it's just the white background but it's tough to see and say.
