Speaking of power options, we have watches that run on battery and those that are solar-powered. With that said, battery-powered watches can offer inaccurate data and lose track of your activities when they suddenly stop working due to a dead battery. The problem can be solved with solar-powered watches, which offer an endless power supply. This option is practical and functional, especially for consumers taking track of outdoor activities.


How do Solar-Powered Watches Work?

how does solar watch work

Solar-powered watches contain photovoltaic cells that convert light energy into power. The watch is capable of recharging even in partial light.

A solar panel is right beneath the watch's dial to absorb both artificial and natural light from the surrounding environment. The light is then turned into electrical energy used to power the watch. Besides, energy is stored in the watch's rechargeable cells to power the watch in the dark. Some solar-powered watches come with lithium-ion cells capable of powering them for a long time without exposing them to light.

Note that the solar watch can charge from any light source, not necessarily the sun, as most people might presume. To achieve sufficient recharging specific conditions must be met. Adequate strength of light and the right amount of time should be considered to recharge the watch entirely.

Since the light in a room is weaker than sunlight, the solar watch might take longer to charge. You will need to face the dial towards the sunlight to charge when you do not use the watch. However, the watch will still charge when you are moving. Most importantly, you should ensure the watch is not exposed to high temperatures.

Solar Watches Pros and Cons

solar watch pro and con

When buying a solar watch, the chances are that you will give efficiency and sustainability much importance. You will want to make particular considerations on the watch to know if it is right for you. In the next section, we have highlighted the pros and cons of solar watches below.

Solar Watch Pros

  • Charged through any source of light

From the name, people will think solar watches are charged only when exposed to sunlight. The misconception tends to lead people into making a wrong judgment in their purchase decision. Aside from the sunlight, the solar watch can be powered by artificial light, such as light from fluorescent or incandescent bulbs. The solar cells under the dial can convert light energy into electrical energy.

  • Low maintenance

Little efforts are required to keep the solar watch running. The solar watch only needs exposure to light to keep track of time. Unlike automatic watches, solar watches do not require special maintenance.

  • Easy to charge

Solar watches are designed to charge easily. As long as they are exposed to a natural or artificial light source, the solar cells can convert light into electrical energy to run the watch. When the dial is faced to light, the solar watch will keep charging.

  • Reserves power for a long time

Some solar watches are designed to store power for up to 6 months. For instance, the Citizen Eco-Drive solar watch is one of the brands that can reserve power for six months without being exposed to light during that period.

  • Long-lasting battery

Batteries that come with solar watches can last up to 10 years. Unlike the quartz watches with batteries that last up to 2 years, solar watches considerably saves you from regular the occasional battery replacements.

  • Eco-friendly

Besides saving on costs, the long-lasting battery reduces the use of disposable batteries hence protecting the environment. Buying a solar watch means reducing the number of chemicals leached from frequently disposed of batteries that contribute to environmental pollution.

Solar Watch Cons

  • Expensive than Quartz Watches

The price of solar watches is slightly high compared to quartz watches. The technology integrated with solar watches makes the price slightly more elevated.

You will not want to go for a luxurious watch when you intended to have a great outdoor adventure experience. Instead, you will need water-resistant options, have adventure based features, and health and wellness specifications.

Power Reserve

The power reserve is a significant consideration if you need a solar watch to sustain power for months without light exposure. This feature can be useful to people who don't wear their watches regularly, as well as luxurious watches that can be used occasionally.

Additional Features

Apart from the basics, you will want to purchase a solar-powered watch that includes innovative features and specifications that can boost the specific experience. For instance, the outdoor enthusiast will need a watch with weather-resistant features, navigation features, health and wellness monitoring features, and entertainment features.
