Telling the Crosshair 1.0's are finicky. I think the frames that start with 12-xxx were the original 2005 runs and NOT the 05-xxx skus. The Titanium 12-871 frames I have (en route from the Champ, so I can't photo) are the OG beveled edge, not the edge with the lip. I'm thinking with the OP's colorway, it's the beveled edge.
However, easiest tell is to get your tiny screw driver to loosen the screw by the hinge and gently pop a lens out. It's easier than X-Metal or O-matter lens swaps.
