looks neat, but this would stop my buy:

""" Use USB charging for the heart rate monitor, step tracker and notifications. Time display is powered by solar charging alone when the battery runs low. """

I have a gshock already (GM-B2100D-1A) and I love it - I especially love that it should never be opened, always just works, and it looks ok too (:

I think it's nice that the watch falls back to effectively unlimited watch-mode instead of shutting down completely because the heart-rate tracker ate up all the battery.

Nah, this is not the first G-Shock with an HRM. This is only the first in the "G-LIDE" series designed for surfers which usually has a tide graph. But there have been Wear OS G-Shocks and G-Move watches with HRM in the past.

This. I was confused because I have definitely seen HR monitor casio watch years(10+?) before.

It's super cool and I love G Shock in general but the Casio app is straight up awful.

Have you tried this open-source app:

A web app i have to host on my own, use workaround apps to connect to it vs a clunky casio app that just works? I’ll go with clunky here

Thanks for sharing this! I'm also looking for an alternative to the official app, since having to log in with an account and accepting a privacy policy every time I want to change the time on my watch is pretty ridiculous – unfortunately I think this doesn't quite fit my use case as usually I'll want to sync the time when I go to a different country, and I'll normally only have my iPhone with me, which won't support WebBluetooth. But this tool might be a starting point to fork and build a capacitor app with that can run on the phone I suppose.

Have you seen what vibe-coded slop it is? It's WILD.

You linked to the Android app there, not the experimental webapp linked above – I'm wondering what gave you that idea though? Those commit messages look pretty human to me, don't think an LLM would ever just commit 'WIP' or 'code cleanup', it's also 4 years old, before the height of vibe coding.

I can imagine the author may have used an LLM for this webapp version of it though

It is hard to reverse-engineer the Casio protocol by vibe-coding. Have you tried it?

How's the battery life on these Casios with fancy features?

My ideal smart (dumb) watch has step/heart/sleep tracking synced to my phone, no other connected features (especially no notifications), and a ~month of battery life. Currently that only satisfied by a Withings Scan Watch or a few Garmin models with the notifications disabled...

Uhm the caption isn't remotely correct? Casio has had a G-Shock with heart rate monitor and smartphone link for years now. This is the first G-Lide series watch with these features however.

It's a cool novelty but as a sports+tech+watch enthusiast (I guess which makes me the ideal target market for it), it doesn't speak to me. It's far too chunky at 17mm (that's 0.66 inches) and the fact I would need to charge a "legacy" watch has no appeal to me.

I want this in the classic F-77W or F-91W shell. Has this been already done neatly?

> smartphone pairing enables automatic time correction

I like how they're advertising this shitty feature that's much more cumbersome than what their watches have now, namely https://gshock.casio.com/europe/technology/radio/

More like, automatic time correction is the best reason we found for mandating smartphone pairing and we hope you won't remember there's a better solution.

Also, 35 days that the battery lasts is 1/10 of a year, compared to 10 years that radio-synced watches have, so two orders of magnitude less. Fuck off with smartphone pairing, Casio.

edit: 35 hours, lol, so more like three orders of magnitude less.

Waiting for a watch that can measure respiratory rate.

Yay for the heart rate, boo for the smartphone.

Casio/G-SHOCK, one of the few brands which I think could plausibly stretch/apply itself into more tech areas than it currently does. Wearables, re-entering the market for ruggedised android phones, etc.
the_gipsy
I have a G-Lide and I love it for the tide stuff and general toughness. I have Bluetooth disabled though, I want the battery to last like a normal non-smart watch.

I don't understand Casio watches. I know that aesthetics are highly subjective but, outside of retro nostalgia, does anyone actually enjoy looking at this thing on their wrist?

The massive plastic bezel shouting PROTECTION, G-SHOCK, G-LIDE, random text on the display like SOLAR POWERED, HEART RATE, START-STOP, SHOCK RESIST, WATER RESIST 20BAR, TIDE GRAPH, besides the permanent function labels, all strike me as childish at best, not something an adult would wear unironically.

Meanwhile, I wish Casio had more power-saving magic to bring to something GPS based rather than yet another fitness tracker. Don't really need/want HR monitoring for hiking, but do care about position, elevation, tracking, and navigation functions on the watch itself.

I guess the reality is that this really isn't a "watch" anymore and Casio knowing how to make very low power, solar charging watches doesn't extend to computing and GPS.

I still have my G-Shock from the late 80's. It has a crappy light, a quiet alarm, and limited functionality.

But it's damn near bullet proof and I change the battery every few years.
