ZIIIRO Gravity: Black OceanThe ZIIIRO Gravity presents a simple and unique way of reading time. The tip of the inner swirl represents the current hour, while the outer swirl displays the minutes, with a continuous gradient movement showing the passing through time. Resting on our patent pending bracelet strap, it combines silicone and metal to form a flexible bracelet watch. Please note: all our watches do NOT include batteries.
