A Watch Whose Time Has Come…
Doesn’t a solar powered watch just make sense?
It’s an idea that I instantly fell in love with when I heard about it. Being that I spent a lot of time outdoors walking, and especially now that as I type this it is summer and about bright and sunny at around 72 degrees outside, it’s easy to imagine how clever wearing a watch that’s powered by the sun really is.
How Does a Solar Powered Watch Work?
You’ve probably seen a normal battery watch before. They’re like a small looking coin, silver in color, and made out of lithium. And being that they contain only a finite reserve of energy, eventually they will have to be replaced or manually recharged.
Solar powered watches, on the other hand, use a solar powered battery that will harvest energy on its own via the sun, and thus should never have to be replaced. These watches are naturally recharged via solar energy.
Somewhere on the top of the watch there will be a set of small solar cells. These solar cells will convert solar energy into electricity. This electricity is then charged into the battery. A rechargeably battery can often be recharged about 1,000 times.
Pretty cool, huh?
How Well Do They Work?
The question really is “Do you have to be in the sun all the time?”
No. You do need to let it charge occasionally, of course. But many watches hold the charge quite well. In fact, this watch from Casio can stay on for an entire year once it’s charged.
