From the project
Sci-fi inspired electronic watch. MK4 currently 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.
