Using a unique ring-shaped solar cell that sits underneath the covered glass - instead of beneath the dial as in most designs -the Eclisse watch never needs a battery change and offers six months power reserve once fully charged, according to manufacturers Citizen. A reduction in the surface area of the solar cell is counterbalanced by the increased light receptivity, generating enough electrical current to supply the movement which itself has been designed to use less energy.

The completely self- sufficient Eclisse also features a calendar, push button deployment buckle and water resistance.

The silver Eclisse costs AUS$550 and the two-tone model is AUS$599. Phone 1800 069 098 to find the nearest Citizen stockist.
