I did have a G-S CMY304-10 crystal and I tried it.
It will fit the case but the curvature from the 12 to the 6 position is just a tiny bit too much and it's a domed crystal and the sides of the crystal make the minutes track hard to read when looking straight on. I will try to locate a G-S MY302-10 crystal and report how it fits when I do.
