Watch Wyoscan 0.5 Hz is a reverse-engineered Casio digital watch. A tiny computer inside has been reprogrammed to slowly render the current time from left to right, scanning across its liquid crystal face, completing 1 cycle every 2 seconds.
You’ll notice that reading this watch requires more attention than usual, as the seven segments of each digit are lit one by one across its display. This speed may be adjusted until it reaches the limits of your perception. You and your watch are now in tune.
