Energy innovation for watches As manufacturers create an ever-increasing number of watch functions, Sunpartner Group is helping to make them more efficient, using less energy and without affecting the watches’ design.
Thanks to our revolutionary technology that produces energy by harnessing natural and artificial light, the ultrathin, transparent photovoltaic Wysips Crystal® component can be integrated into any glass surface.
- Advantages of Wysips Crystal® Watches
EconomicalWatches are more energy self-sufficient which results in lower overall battery costs, whether the batteries are regular, rechargeable, or high-capacity.VersatileThe electricity generated offers manufacturers the immediate ability to increase the number of watch applications and functions without affecting aesthetics.SustainableSmaller battery size, as well as lower cost for energy storage, reduces the watches’ environmental footprint.
Wysips Crystal® technology
Wysips Crystal® technology is incorporated during manufacturing, either beneath or on top of the crystal. The transparent component is connected to an electronic chip that converts and manages the power produced. The photovoltaic component continually recharges the battery totally eliminating the need to ever change the watch battery again.
