Born from state-of-the-art technology in the field of renewable energy research, the quartz movement of «Nitella Solar» is powered exclusively by light captured in ceramic cells around the rim of the dial. The energy is stored in a capacitor, guaranteeing two months’ power-reserve even when the watch is removed from any light source. The elegant water-resistant case is gold-plated or in palladium and comes with several variations of dials and straps.
