Ask a smart watch owner what their favorite wrist-mounted feature is, and they might say it’s having all their daily information available at a glance, or the ease with which they’re able to communicate with friends and family. If they don’t mention knocking out a few lines in their wearable BASIC interpreter, then you know you aren’t talking to [Nick Bild]. His “C64 Watch” firmware for the LILYGO T-Watch 2020 not only takes some visual inspiration from the Commodore 64, but also lets you relive those early computing glory days with a functional BASIC environment.

Originally [Nick] used a teeny tiny onscreen keyboard to tap out his BASIC programs, but finding the experience to be uncomfortably like torture, he switched over to using USB. Just plug the watch into your computer, open your favorite serial terminal, and you’ll have access to the customized version of TinyBasic Plus running on the watch. To make things  even easier, he’s looking at implementing a web-based terminal over WiFi so you don’t need to plug the watch in.

When you aren’t running BASIC you’ll be treated to a Commodore-themed watch face, complete with the classic READY. prompt. A small battery indicator is hidden up in the top-right corner, and tapping on the rainbow colored “C” will launch the menu. It’s pretty simplistic, but of course what else would you expect given the source material?

Looking ahead, [Nick] says he’d also like to implement a C64 emulator into the firmware so the watch could run original software. We’re a bit skeptical about how practical that would actually be, but we’ll reserve judgement until we see it in operation. He’s also hoping other Commodore aficionados will chime in with their own improvements and new features for the watch.

You might think that a Commodore 64 emulator on your wrist would be the most outlandish way to run your old games and software, but we’d say playing Turrican in a virtual reality microcosm of the 1980s takes the cake.
