I chose a vertical alignment of the four time telling numbers. There are three display modes: a) showing the sliced numbers b) moving the parts a bit and c) moving the parts more extreme. Once the wearer got used to one mode, he/she can move on to the next. The covering glass is diagonally embossed, always reminding the wearer of the way the symbols have to be decrypted. My favorite mode is the second one, with halfway shifted parts. The “numbers” still look compact and are easy to reconstruct mentally. With a button, the modes can be changed easily. Another button is for the backlight.
