alt Hacker NewsI spoke with a Casio engineer about this. It's so that your bending wrist can accidentally switch it to 12h time when you actually really want it on 24h time or vice versa.

Is this a joke, or an actual answer?
They could just set it to 12h mode for americans and 24h mode for the rest of the world, and hid the setting somewhere deep in the menus (hold this button for 3s, then press that button 5 times, and then the other button two times, etc.), so you could change it from american to normal display if needed, and never again press it by accident.
+1 I use this all the time and can't live without it
