pexels-mister-mister-380782

Looking for a solar-powered watch? When it comes to wristwatches, there are thousands of incredible options to choose from. They’re a classic accessory, and often a functional necessity used by everyone from keen enthusiasts to people who just need to know the time without pulling out their phone to check.

Quartz watches, which are battery-operated, are known to be highly accurate, precise, and reliable. They’re an affordable, accessible and low maintenance option, which is especially popular with those who need a reliable and hardwearing watch.

The problem? Traditional quartz watches have a battery that inevitably needs to be removed and replaced. Aside from the hassle of finding yourself without a watch and then having to have the battery replaced, opening and closing the casing can impact the seal and water-resistance of a watch.

The solution? Solar watches! Solar-powered watches offer all the same benefits, without the hassle and inconvenience of needing to replace flat batteries!

Solar-powered watches come in all shapes and sizes. No matter what you’re looking for, there is a solar watch for you.

That said, so many choices can be overwhelming and time-consuming to sort through, which is why we have chosen 13 of the best solar watches for you to look at today.

Let’s dive right in!

How Does a Solar Panel Watch Work?

In a solar-powered watch, solar energy is captured by the solar panel of photovoltaic cells under the watch dial. This energy is then transferred to the capacitor, which is a battery-like cell, to be stored and used to power the quartz mechanism of the watch.

Traditional quartz watches are driven by energy from a disposable battery cell, which sends an electrical charge to an internal quartz crystal shaped like a tuning fork. The quartz crystal resonates or oscillates at a very precise frequency. The circuit inside the watch counts the vibrations and sends a pulse every second to the watch motor, which drives the mechanism to move the hands and keep time.

Quartz watches are known to be very precise and accurate watches. Their only downfall being battery life and needing to change the disposable battery when it runs out of charge. A flat battery will lead to lost time and necessitate the opening of the watch to replace it, which can compromise the seal and water-resistance of a watch.

Solar watches, on the other hand, do not need to be opened to replace a battery because there is no battery to be replaced! Given enough light, they will continually charge and keep going for many years.

A good solar watch has a power reserve of up to 12 months, in complete darkness, so it can safely be stored in a cupboard or safe without compromising its accuracy or functioning. If you wish to learn more about how solar watches work – check at this introduction by Superwatches.com.
