How are they getting 2 years on a CR2016? Is that with step tracking and Bluetooth disabled?

Bluetooth is watch initiated, and only turns on 4 times a day (or when the user explicitly requests it with a button press). The pedometer is probably a special chip.

You should compare this with the F-91W that gets 7 years on the same battery, and hobbyist hardware mods that get years out of the same battery running ARM chips.

I guess it's a more complicated thing to implement (!= low hanging fruit), but I'd be more interested in sleep tracking than step tracking.

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...

I had the same thought--speculating, perhaps it's like you say and we'll see a disclosure somewhere that it's "Up to 2 years, with 1 weekly Bluetooth pairing, 1 second of backlight use per day, no step counter."

Though, the CR2016 is a pretty big battery vs typical watch batteries, and in some other Casio watches are used as 10-year batteries.

Right when I started building a custom F-91W with/for my kids based on sensor watch: https://github.com/joeycastillo/second-movement I'll take some solace in mine supporting lots more alarms (beep when school recess ends) and a bunch of geeky stuff like sunrise, moon phases, tides, and stuff.

The sensor watch is actually awesome, if only for turning a cheap casio into a super-accurate quartz watch with temperature compensation.

I'm a huge fan of the Casio F-91W, have two of them on my desk right now. Maybe it's just me, but for this specific model I feel like it becoming bluetooth enabled breaks the spirit of the simplicity of the model.

But hey, seems like people are excited for that, happy for them! Mine will last another 10 years without it.

For anyone interested in modding the F-91W there's also The Ollee Watch, a replacement PCB which adds even more "smart" features. https://www.olleewatch.com/

The developer also recently posted on Reddit that he’ll soon be adding third party app support

Really hoping this will include the ability to sync information from the internet via the BT tethered phone. But probably not

Similar to the current weather feature that grabs the weather for the next 5 days on every sync, I just want to push the local time train schedule just once per day to my watch.

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.…

...evidence that you're a terrorist

Or more recently, to some officials, showing up at a No Kings rally.

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.

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.

Upon seeing "Bluetooth" and "Daily steps" I'd assume this is another watch that requires daily charging, but wow 2y battery w/ CR2016!
