Casio F-91W using Statecharts

This is funny, I just ordered a FOSS replacement movement for the F91W, which, with a few calibrations spread out over a few months, can achieve an accuracy of <15s/yr (it also has an accelerometer and a thermometer built in). I was planning on writing some astronomy and navigation apps for it

If anybody is interested:

This is great. did you leave out the alarm ringing and the continuous increment when holding the A button because they were hard to model or just to keep the demo simple?

It renders funny on Firefox mobile for iOS.
