That crystal doesnt look right to me. The letters of Casio are just not crisp enough. I may be wrong but that what I think.
It is a W-450 (aftermarket) crystal
This is a Casio Frankenstein:
Case of Casio W-24 with fake W-450 crystal.
Hello, i'm with DWL crystal is not correct or is a bad quality, case is correct i think, for the 4 circles in the corners.
