1. Environmentally friendly solar technology
Technology that requires no battery! Light – whether sunlight or artifi-
cial – permeates the solar dial or the light transparent dial. This trans-
forms the light into electrical energy, which is then stored in a long-
lasting energy store. The energy store serves as an energy source for
the solar wristwatch and enables the watch to function – even in com-
plete darkness.
