I got one of these guys watches, it has an RFID chip but I can’t think of anything to do with it. It looks really cool though. The light is nice too since its bright enough to use as a flashlight when its dark enough.

I use to work at a place that included parking in rfid activated ramp. I always wanted to clone my badge into something sewn into the wrist of my motorcycle jacket so I didn't have to fumble for my badge while entering and leaving the ramp. In a watch would be perfect.

Can the ROM be read and flashed back on Casio watches? I once bought a solar G-shock but the watch UI is horrible: it does not display the battery charge anywhere on the watch. Instead, it wants you to install a Casio app that connects to the watch via BT. However, even the app doesn't show the battery charge with more than a few scrambled pixels in a small icon. So, useless. I still don't know how much battery I had…

I doubt that they use any kind of reprogrammable memory, but you can swap out the entire board like I did: https://github.com/carrotIndustries/pluto

I got a Casio watch from Amazon about five years ago, there was a deal on and it was about CAD$20. A budgetary driven decision, for sure! But it's been fascinating to see, over the years, how many times I've been approached (in a coffee shop or some other public place) by serious Casio enthusiasts, keen to ask about my watch and to show theirs. There's so many variations, colours, limited-runs editions... I seem to h…

I recently got a $20 Casio watch as well. Unlike the Garmin watches, I never have to charge it. It tells time and that's it. I never noticed how often I checked my phone just to check the time until I got this watch. I love it.

I've noticed how often I check the time on my phone. Tapping the screen isn't a big deal but I still feel like a flick of the wrist would be more convenient, and there are times when the phone isn't right next to me.. Also, digging a big phone out of the pocket and putting it back when I'm on a walk is worse, nevermind doing that while driving a car (the clock on the radio seems to be always wrong).

So I've been thinking about buying a watch for a couple years now. I finally did it last Saturday. Coincidentally, a Casio, and thanks to this thread I'm even more excited for it than before :) It hasn't been shipped out yet.

Shocked someone has not posted the article about why its so popular among al-Qaida. Always a fun read. https://www.vice.com/en/article/pkebp8/casio-f91w-watch-terr...

amazing takeaway paragraph:

> United States Intelligence quickly noticed the prevalence of F-91Ws on the wrists of Islamist fighters. Secret files about the Guantanamo military detention camp published by Wikileaks say Pakistani authorities discovered some 600 to 700 Casios in two workshops in Karachi, and that simply owning one could warrant an interrogation. One prisoner’s evaluation sheet confirms “about a third of inmates at JTF-GTMO [the unit in charge of Guantanamo] who were captured wearing one of these watches had a known correlation with explosives”.

I did the opposite. Wore a Seiko 5 for a while until I got tired of not trusting it, then switched to an F91w. The Seiko is very good for an affordable automatic, but it’s hard to beat a quartz for “it just works”.

It sounds like yours needed regulation. Properly regulated you can trust them just fine.

It wasn't out of spec, I'm just referring to the general weaknesses of automatics. If I spend the weekend doing physical activity where I don't want to wear a watch, Monday morning I'll be resetting my Seiko 5. With my F91w, I can take a long vacation, and spot check a system clock to the second when I get home.

I've been wearing a Casio F-91W for a number of years now and it really is a joy. It's always there, and it always works. I've gone down the rabbit hole with expensive time pieces but they become a burden / obligation rather than a tool - especially as the prices of certain pieces in the secondary market have gone so high - so over time I've reverted back to much cheaper watches and find myself getting more joy out o…

I buy one every year or so I go to Japan purely on impulse but in reality, there are hardly any occasions for me to use such sandwich products when the decision is between an Apple Watch as the daily driver and a Tag Heuer for a night out.

If you stop thinking about the Apple Watch as a watch and more as a data collection and display device, maybe dual-wristing would be an option?

It's not that unusual to see people out with a watch on one wrist and a fitness device on the other wrist.

I got a couple of casio watches from Amazon years back. Then I brought one in a physical watch store and realized that all the watches purchased through Amazon were fakes. Especially the strap is so much better on the real thing.

I wouldn't have been surprised to find out my F-91W was counterfeit! But I just went and watched a "30 ways to tell if your Casio watch is fake" video on YouTube and it looks like my watch is legitimate. I probably wasn't careful enough with the strap, it just disintegrated at one of the connections to the face.

> it just disintegrated at one of the connections to the face

That's a very common problem on the inexpensive Casios. When it happened to my watch I found that new watch cost less than a new strap.

Hmm, a MicroSD card is handy, but how about a MicroSD card to USB reader in the watch strap ?

On an earlier page[1] the author mentions that they at one point "designed a more complex backplate which included […] a built in micro SD card reader, that you could read directly by plugging in a micro USB cable", among other things. Unfortunately, they go on to lament that this made the watch comically thick. As you say, the strap might be a good place to cram a USB interface without bulking up the watch body.

Timex and Armitron are the two others that come to mind.

Also Braun. Beautiful but pricey. https://braun-clocks.com/collections/digital-watches

Weird. It briefly shows a watch but changes to "No products were found matching your selection." But if I inspect the network tab, I do see the file:
