SEIKO is a world leader in energy efficient watchmaking, and its range of zero-battery solar watches makes it an environmentally sound choice to back the project. SEIKO is proud to sponsor icaré 2 and Klaus Ohlmann as part of its Clean Energy program.

SEIKO Solar is a quartz watch which takes its energy from light, and stores it in a self-recharging battery which never needs to be changed. By eliminating the need for battery change in a quartz watch, SEIKO Solar makes an obvious and important contribution to the cause of a healthier planet. SEIKO was an early pioneer in solar watch technology, with its first Solar watch being launched in 1977.
