Binary is a new model by Zzero watches, and its vintage style is accompanied by a strange method of indicating the time. The display is based on the binary system, with coloured LEDs that change incessantly. The user has to add the numbers that are lit to read the hours and minutes. Its unusual visual appearance is hallmarked by a large dial, metal case, and leather strap. It is available in two models, with case in metal or black finish.
