Common Questions Regarding Solar-Powered Watches

As promised, we’ll answer some pervasive questions that many people face in searching for a solar-powered timepiece. 

Q: What Does Solar Mean On A Watch?

A: A solar watch is a timepiece that converts all sorts of light into electric energy. The light is absorbed through a solar panel under the crystal and then converted to electrical energy, which eventually powers the watch. The surplus power is stored in a rechargeable cell and is used when the light’s not present.

Q: What Is The Best Solar-Powered Watch?

A: Determining the best solar-powered watch is difficult due to the different expectations and points of evaluation. But what is certain is that it is from either Citizen, Seiko, or Casio. Citizen’s Eco-Drive technology is the most widespread, while Seiko Solar has the best selection of solar dress watches. Casio’s Tough Solar, on the other hand, is the best choice for extreme conditions.

Q: Are Solar Watches Better Than Battery?

A: Yes, solar watches are way better than typical battery-powered wristwatches. When a regular timepiece requires battery replacement every 1-3 years, then a solar watch recharges its cell constantly when the light is present, in that eliminating the need for a new battery. The convenience is on a whole new level.

Q: Do Solar Watches Last Forever?

A: Apparently not. Although rechargeable batteries last a very long time compared to typical disposable batteries, their charging capacity will degrade due to long-term use. It is said that a typical solar cell needs a replacement after every 10-15 years.

Q: Can You Overcharge A Solar Watch?

A: No, you can’t. A solar watch has an overcharging prevention function that automatically activates to prevent the battery from being charged further.

Conclusion: Best Solar Watches

Solar power is one of the handiest functions in a watch. Not only it provides ultimate convenience, but is also eco-friendly, with a good reputation, and is available for a very affordable price. The best solar watches come primarily from renowned brands such as Citizen, Seiko, and Casio. Recent times have seen some other watch manufacturers join the list. For instance, the likes of Tissot, Timex, and Garmin have earned great feedback for their solar watches. Therefore, a watch from the mentioned brands is definitely a good fit.
