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.

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 f…

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

Here is a fun fact; the US believes owning and wearing an F-91W is evidence that you're a terrorist so much so that they can place you in Guantanamo Bay without trial[0]: > In a handful of cases the detainee's possession of a Casio watch or the wearing olive-drab clothing is cited as evidence that the detainee is an enemy combatant. No basis is given to explain why such evidence makes the detainee an enemy combatant.…

It's not quite as simple as "if you have one of these you're a terrorist" of course; it's one indicator based on long-standing patterns, but never used as sole proof. AQ training/bomb-making manuals from the 1990s–2000s recommend cheap, reliable digital watches like this as timers for IEDs as they're extremely inexpensive and widely available worldwide, durable, water resistant, and easy to modify as delay timers. Of…

> Ramzi Yousef (Philippine Airlines Flight 434) and Ahmed Ressam (the 'Millennium Bomber') both had them.

This is like a statistics 101 question. Google says that Casio has sold over 100M F-91W's since 1989. Let's round down to an average of 2.5M a year, or 25M over the 10 peak years of the global war on terror (GWOT).

You named two terrorists who wore them. Let's say that's an understatement by 200X. Some quick math shows that the percent of terrorists who wore F-91W's is 400/25000000 = 0.0016% positive rate, or conversely a 99.9984% false positive rate. Not good!

Now I never actually took a statistics class, so maybe I got this question wrong. But it's obvious that using the possession of an F-91W as a sign of being a terrorist is a mistake.

I would love a watch in the F-91W form factor that does heart rate and sleep tracking. Maybe one day…

I’ve seen some people put something like a Whoop on the opposite side of their watch, so theoretically the functionality is achievable, but I can’t imagine the form factor to work due to the demands on compute and battery heart rate and sleep tracking need.

Another alternative is a smart ring.

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.

Step counter seems like a bizarre thing to focus in on? are people passionately tracking steps without their phones?

> Step counter seems like a bizarre thing to focus in on? are people passionately tracking steps without their phones?

Yup. I go for walks specifically to leave my damn phone at home. I do bring an Apple Watch w/ airpods in case I need to take an urgent call and for podcasts, but I don't bother with texts or alerts or any other nonsense.

And while step tracking is not critical, if you have health goals that include a minimum number of steps a day I find it incredibly nice to have. I can check my counter before bed, and take the dog for a 30 minute walk if I'm behind for the day. Just a means to hold myself accountable on those crappy low energy stressful days.

shame it doesn't have notifications, otherwise it would be perfect so I guess I'm staying on my third Amazfit Bip since Pebble Time 2 has insane price

If you want a coin-cell powered watch with a couple of years battery-life, but still want notifications, the G-Shock GBD-200/300s have this feature: https://www.youtube.com/watch?v=wCq1ei5cT_8

It's not great... but it's something?

My phone is sitting on my desk now connected to a charger - meaning any pacing I'm doing at the moment it not tracked. When I cook I often set my phone on the counter with the recipe - again while I'm moving all over. I often go to the bathroom in the middle of the night without bringing my phone. I hate watches, but one would be better for step tracking - it is more likely to be on me to track information.

Just go run or go on a walk every day.

Earlier quoted context omitted.

Sure, but we can't do sleep tracking well. Todays devices mostly guess and map to typical patterns. Might, might not, work reasonably for you. But chances are that if you want to track your sleep because you suspect irregularities then they are about as useful as a potato.

The Apple Watch is quite accurate (according to Apple's own research, at least), and it doesn't guess or map to typical patterns: https://www.apple.com/health/pdf/Estimating_Sleep_Stages_fro...

From other anectdata the apple watch seems to just as bad as everything else.

We just don't seem to have any idea how to track sleep quality even with better devices than just a watch/whatever. Even a binary, is the person I'm attached to sleeping, is hit and miss. And with that in mind you can be pretty sure that the sleep stages etc is even worse.

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.
