I have a rectangular silver dial Crazy Hour, and I bought a lozenge shaped crazy hour colour dreams in pink for my daughter.
I picked up a gen pink lozenge dial and a gen ruby red rectangular dial, and as you know sometimes toumii sends along a free dial with each you buy so I also have an immaculate gen dial exactly like yours which I now intend to use. The final dial is a gen non-crazy pink dial and I do not know what I'm doing with that one yet.
I was thinking about DLC'ing the rectangular case and dropping the ruby dial into it with a maroon horn back strap. That's the plan, anyway.
