Designed specifically to be Riiiver*-compatible, our Eco-Drive Riiiver watch offers new ways of experiencing time: get the watch hands to point you in the direction of a nearby café; check up on the score of the big game; use a unique shared signal to arrange a meet up with your friends. Beyond the ordinary concept of a watch, the Eco-Drive Riiiver will update your lifestyle and change the way you live. Featuring our Eco-Drive technology – powered by light, any light. Never needs a battery. *Riiiver is a micro-community service that organically links devices, services, and people.
