From the How-To's:

Although the MCU I'm using runs at a blistering (by early 1980's standards) 72 MHz, the watch functions are mostly parody of the modern Apple Watch. My version does keep and display the real time and date, the rest of the UI is mostly for fun. I considered spending the time to add a BASIC interpreter (either Woz's Integer Basic or perhaps Tiny Basic), but the return on my time would be diminishing. I spent about 3 weeks casually working on the case design and basic circuitry and another week on the graphics and software.
