The whole case is ti. Not sure about the screws though. I just received it today. Quick thoughts of mine:
A very solid build, as usual.
They nailed the dial grey and case color. RG color is bit too red, as the case of every JF RG AP.
They failed at the subdials though, which are matte on the gen. I'm also a bit disappointed wth the caseback engraving now since it's almost flat with the surface, only a minute bit of depth. The detail itself however, is very good.
Some pics.
