Sci-fi inspired electronic watch.
MK4 in the development, out in 2026.
When the button is briefly pressed, SW63 tells you the time using a sequence of LED blinks. It's not a binary clock, it's inspired by the analog clock hands movement and uses quarters, halves and so on; similar to how people used to tell the time before the digital clock became popular.
16:35
half past - four - hours - and - five - minutes - PM
6:57
three - minutes - to - whole - seven - hours
Language can be changed in the watch menu to reflect the different ways different languages express the time ("half past five" in English is "half of six" in German etc).
See LANGUAGES.md for the full list and examples.
