Check out the 'complications' section - there are a bunch of additional features you can add - moon phase, timers, TOTP Generator, invaders game and more. https://www.sensorwatch.net/docs/watchfaces/complication/

This would seem more useful on something like one of the calculator watches or I know I once had a watch with a TV remote built in, not sure offhand if that one was Casio, but that'd seem like something more useful to have in a watch.

I had one of those remote control watches, it was a Casio CMD-10 https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fn...

It is years since I longed for something with such primal raw visceral yearning!

I need a VCR remote on my wrist!

Casio: Best I can do is a calculator.

I feel like mine was a different model that was not as colorful, but very similar otherwise. It was always fun to control TVs in public and nobody would know who did it or how.

TOTP generator? I never knew I needed this until now. It's also got a pulsometer which is great. I'm gonna try to hack an asthmometer into it as well.

TOTP generator is more useful if it uses NFC.

It's a fun and cheap project for anyone just tinkering with electronics.

Like the ben eater kits - it's not really useful, but it's fun to do and then have

I enjoy this simply to have sunset, sunrise, and moon phase on my wrist. The added precision from the finetune watch face is a nice bonus.

If I could make one change to my F-91W it would be to use top right number (normally day) to use as an hours counter in stop watch mode. Right now you can only measure 1 hour.

At the really simple end, I’m using it to prevent my watch from accidentally switching out of 24h mode, and to disable the hourly beep that can be accidentally turned on.

I found this watch because I could not find anything with more than 2 timers. I wanted a watch that has 5+ for cooking. This watch doesn't either, but I'm writing a face in rust to support this case

I also want sunrise/sunset time, random number generator, and hourly beep+30m beep like a ships clock

There's a Sensor Watch simulator that demonstrates the features of the various firmware images; this one[1] is running the firmware that shipped with the first boards, and includes a clock, world clock (UTC by default, but customizable by holding the Alarm button), sunrise/sunset, moon phase and temperature. For the sunrise/sunset to work, you'll have to click the "Set Location Register" button, which will prompt for location access.

There are other versions of prebuilt firmware here[2], but my favorite one (even if it's a bit impractical) is the Stargazer firmware[3], whose second watch face can display the locations of the sun, moon and seven planets both in right ascension and declination, as well as altitude and azimuth if you grant location access. We're able to fit a truncated version of the VSOP87 model for planetary motion, right there on your wrist.

I own the previous version of this. That's all I have to say.
