One 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.

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.

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.

They had modal menus back then, they just didn't display them. You had to memorize which obscure symbols to press, to change various settings. For example, in the 1970's, HP's calculator watch required pressing ⯅• to switch between 12 hr and 24 hr modes, or A⯅A to clear an alarm.
In the 80's and 90's, when sixteen-segment and dot-matrix displays made displaying text easier, calculators started displaying menu items, so you didn't have to memorize the sequence.
Since then, we've moved on to full-color high-resolution displays that can handle any text of any language, and the menus have more-or-less switched back to memorizing a sequence of which obscure symbols to press, I guess because some people think they look cool? Sometimes there's no menu at all, and you just have to memorize finger movements.

To add to it, I always kept the manuals around, because remembering the key press sequences was akin to doing combos in arcade fighting games.
A few months without doing them, and it was hopeless trying to remember how to do them again.

I always followed trial and error until I reached my target and I had the feeling that my results were much better than if I were randomly clicking buttons. That is, some memory always remained. Or the menu is well thought out and has some consistency.

The button press sequences are still combo-style; when I set one of the alarms on my ABL-100WE, it always ends in trial and error. I mean, basically it's logical, but when the buttons change what they do (e.g. when the display says "SET", the light button becomes "up"), it throws me off.

I have a 6.30AM alarm on my FW-91, and I'm too lazy to figure out how to switch it off.
15 beeps, btw, till it turns itself off for the day.

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.

Yes but why not just always use 24h time (or 12h if that’s what you like).
It’s a little strange that a dedicated button would be needed to switch between them, especially when the math to convert between them is so simple.

OK, but who would use 12h time ? I never understood, this seems so backwards.

How about someone who was raised on 12h time and has used it for 70 years? Sure, the math to convert is pretty easy, but why?

How about just leaving it on 24h time all the time?

My F-91F I replaced the Casio module with an Ollee watch and pretty much disabled all of the features, I can sync the time when reconnecting to Bluetooth on my phone which I do about once a month.
