ZIIIRO Watches display time in a simple and unique way: the inner swirl's tip represents the current hour, while the outer swirl displays the minutes. On the ZIIIRO Mercury and ZIIIRO Gravity watches, a gradient movement shows the passing of time.

The ZIIIRO Aurora watch and Proton watch, however, use two transparent discs: by overlapping both gradients, an attention-grabbing array of green displays the time. See also the ZIIIRO Celeste watch, whose discs blend blue and grey. Finally, floating spheres instead of hands make the ZIIIRO ORBIT watch (pictured) different from the rest, with a colored orb representing the hour and a white one displaying the minute.
