Just like the Nintendo Wii - graphics didn’t matter, it was just so entertaining!

As a 10 year old I once played NUMBER INVADERS for 12 hours on my Casio calculator watch uninterrupted. My parents were very concerned :-)

I bought a Casio recently and I was curious about the mechanism, but I couldn't find anything. The only detail that I found was the frequency of the crystal.

Regarding the controller, the best I could find was a few posts with people theorising about it being an ASIC or an MCU.

I guess Casio is good with secrets.

That reminds me of my old Timex Datalink watch which was one of my favorite watches I have ever owned. It was the Ironman Triathlon[0] edition and I was unusually sad the day it died. I got that watch because it was "space certified" and used by astronauts on missions.

The USB edition was kinda neat but just didn't have the same charm of the previous models but certainly had a lot more capabilities including games. I believe this is the Timex watch the article is referring to.

I had a small collection of favored LCD watches in the 80's, including the Scramble Fighter game mentioned in the article .. as well as a few other neat ones, including a DataBank and another Casio which featured 15 tunes/melodies and a small sequencer for composing ones own, which was always a delightful use of time while waiting for the bus.

These days I also have a set of watches - from the PineTime to some TTGO vendor-machine clones, an Oscilloscope Watch and a Watchy by SQFMI. These are mostly just hacking toys - fulfilling the fantasy of having a veritable toolbox of devices to lug around on my wrists - but rarely being actively used.

Well, except for the Pinetime, which I've lately taken to wearing more often to count steps and track heart rate metrics.

That said, this article has lit a fire on the subject of PineTime extensions, and I think I am seeing a future series of watchfaces and smaller apps inspired by the Casio era, on my horizon .. would be fun to have a Casio simulator with a few of their watchfaces on the PineTime - which, for all of its quirks, is a darn cheap way to carry time, even if the current set of watchfaces/apps for it is a bit .. mundane .. to put it politely.

Anyone up for some CASIO inspired PineTime watchfaces, or know of any already? Or maybe for the SQFMI/Watchy, perhaps? Maybe its time to crack out the devtools ..

Hey, there's a thought. I do have these cute little JS-programmable smartwatches now, and a "digital crown" jogwheel seems like a good fit for Tempest...
