Yet another unique innovation with sustainability in mind. This watch, called Black Solar, is driven by solar power. Aside from the stunning design this watch has a solar panel installed beneath the dial that gathers sunlight and powers the movement.

The Black Solar Sewn comes with a sewn watch strap made from recycled PET bottles.

The solar power technology in the collection uses natural or artificial light as operating power. The dial of the watch channels the light to the solar cell underneath the dial which collects and converts it into electricity. This electricity activates the motor of the watch so that excess energy charges the integrated battery. Having been fully charged, the watch can run in the dark for several months.
