alt Hacker NewsOne thing I've never understood (and hopefully some Casio geek can shine a light on): why do almost all old Casio models have a 24/12h time switch taking the premium spot as one of the main 4 buttons, instead of having it buried deep in the (awkward) menus. Seems to me that something like alarm or stopwatch setting or a second menu action button would have been far more useful.

In my country, 30-40 years back, people who needed a watch were those ones who travel regularly. And travel was mostly using public transport, trains and planes. Most or all of it operated using a 24h time. That button was very useful. Compare that to the mute/silence/DND physical button in iPhones today.
Also people who worked in confined spaces who wouldn’t know if it was day or night outside after a days job. My father who worked in an oil rig in Abu Dhabi used one. He gifted me one.
This was 1998.
Those buttons are the menu. The idea of menus on watches is a modern ux extravagance.
I don’t have the satisfying answer as to why they dedicated a button to 12/24 hour time but my guess is that it’s simply a cool digital feature and stands out against the limitations of analog watches.
I 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.
