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.

This is also noted on the F-91W's Wikipedia page:

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.

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

It seems to me that it's a slightly more affordable repackaging of the ABL-100WE. The features are the same, so is battery life.

That said, I really like this because the ABL-100WE comes with metal bands and I'd really like another watch with a rubber band :)

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

Like their G-Shock watches, the actual area dedicated to showing the time is overwhelmed by superfluous elements. Must be barely 20% of the top surface that actually performs its primary function.

When I look at my watch I want to see the time, not wasted space announcing "Casio Step Tracker" or "Water Resist" ( which isn't even proper English).

I moved to Timex a few years ago as their basic digital watches have nice big numerals for the time display.

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.

muhammadusmantoday at 5:34 PM

would some Casio/watch expert know if it's possible to replace the face plate on these watches? I love the simplicity but I don't like all the text outside the watch itself like "Step tracker" and "Water Resist".

I love Casio watches, perfect blend of utilitarian and nerd. Wearing my 5000U-1JF right now.

kylemaxwelltoday at 4:10 PM

I have two of these (wearing one right now!!) and several other cheap Casio watches. Some of my favorite purchases ever. I'm so in.

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

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

Not the first new F91W-ish model in 40 years but still neat, I hadn't heard about this one yet, thanks for sharing.

devindotcomtoday at 5:41 PM

Personally not at all interested in these new features - an F-91W that needs a smartphone to operate properly is madness to me - but I do appreciate the way they implemented them, with a focus on longevity and simplicity.

tavisotoday at 4:30 PM

I have one of these, there is an open source project called gshock_api that supports it. I think that makes it a much more interesting device. I don't use the app, I tag alarms in remind, and sync them from cron - works great.

https://github.com/izivkov/gshock_api

The full lifelog (what Casio calls the steps and other metrics) is an opaque binary blob, but we mostly understand it now, so you can access that too.

Not bad!

After wearing an Apple Watch for almost a decade, the F-91W became my new "never take off" watch. For daily use, the only thing I miss from a smartwatch is a weather+temp forecast complication. Interestingly, it doesn't seem like this F-B100W-1A provides that (yet).

d_silintoday at 3:34 PM

Neat. Note that battery life is reasonably good (2 years) even with Bluetooth sync feature.

i love the product design aspect of a product that only needs to have one thing set (in this case, the time zone), to be eternally a functional device

which is why i love gshocks, both for design but also specifically the ones with tough solar/multiband 6 (and bluetooth (optional))

they have battery lives in the range of decades (due to solar charging), set themselves (multiband 6 is using atomic clock radio signals) and via bluetooth

you can get gw-b5600-2 and gw-s5600u (auto backlight) for under $200, but usually closer to $100. there are many more models, of course

that sounds expensive, but it's insanely durable construction and battery life means it'll be the only digital watch you'll ever need to buy. and the only configuration it will ever need is the time zone.

Ekarostoday at 4:47 PM

Started looking at Casios. Now I am thinking of getting W-800HD-1AVEF. Old A159W is kinda broken or pain to get right. Not really using one often, but maybe a few times in 10 years clock would be reasonable.

suncemojetoday at 4:21 PM

Nice move! I wish it would support even more activity / health features in the future like GPS tracking, sleep tracking, etc. As a full package in the classic design it would make a great alternative to Garmin / Polar / Whoop / Oura etc.

RobCodeSlayertoday at 4:58 PM

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

_Donnytoday at 4:41 PM

I feel that the smartphone connectivity feature is a departure from the philosophy of the F-91W. Is having a smartphone for "Easy watch setting" not a flaw of the watch, rather than a feature?

I'd love if it was radio controlled and charged with solar. And without phone connectivity.

How does it do step tracking with a 2 year battery life? A purely mechanical step tracker?

pjmlptoday at 4:46 PM

Nice, still have my original Casio and Timex ones though.

Echo4309today at 5:12 PM

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.

johnnyApplePRNGtoday at 4:26 PM

Why the hell is there bluetooth in it?!

i don't want my casio to be smart. been rocking my mq-24 for a decade

doesn't mean others can't want a smart casio, but, it's not for me :D

sparklingtoday at 4:27 PM

It's also a bump up in overall size. The OG F-91W wears very tiny on a larger wrist.

F-91W (old): 38.2 × 35.2 × 8.5 mm

F-B100W-1A (new): 41.9 × 38.1 × 8.8 mm

bradleyg_today at 4:13 PM

Does it fix the terrible backlight on the F-91W though..

NOPE! No wirelesso in my watch, and there's no way you're getting 2 years on CR2016 when we compare stuff like AirTags.

Markofftoday at 4:11 PM

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
