What Is Casio Tough Solar? All About Casio's Solar-Powered Technology
Replacing a battery every few years? With Casio Tough Solar, that's often a thing of the past. This innovative technology converts both sunlight and artificial light into energy, allowing the watch to continuously recharge itself.
Casio developed Tough Solar to make watches more reliable, low-maintenance, and durable. Today, the technology is used in several popular collections, including G-Shock, Edifice, and Pro Trek.
How does Tough Solar work?
Beneath the dial is a solar cell that captures light and converts it into electrical energy. This energy is stored in a rechargeable power cell that powers the watch.
Even when the watch is not worn for some time, a fully charged Tough Solar model often has a power reserve of several months.
Why choose Tough Solar?
Tough Solar offers several advantages over a traditional quartz watch.
You benefit from, among other things:
- charging via natural and artificial light
- less maintenance
- long power reserve
- reliable operation
- no regular battery changes
This makes Tough Solar particularly suitable for people who wear their watch daily.
Tough Solar or a regular quartz watch?
A Tough Solar watch is fundamentally a quartz watch, but it draws its energy from light instead of a classic disposable battery.
This combines the high accuracy of quartz with extra user-friendliness and less maintenance.
