Solar Watches: The Sustainable Future of Watches

The watchmaking industry has witnessed several innovations over the last two centuries. From integrating a perpetual calendar to improving water resistance capabilities, watches have become more durable and reliable today. Another modern innovation that is changing the dynamics of watches today is the solar function. Solar watches are becoming incredibly popular and are growing in demand. In this article, we explore and learn some important details about them.

What are solar watches?

Watches powered by solar rays are referred to as solar watches. There are multiple different types of solar-powered watches available today. Some of the most common ones feature light receptors on the dial. As you read further, you will learn more about the basic features and functionality of these timepeices.

Features of a solar watch

To help you understand the characteristics of watches powered by solar energy we have provided you with an elaborated explanation of its features mentioned below:

  • Solar panel
  • Power reserve indicator
  • Rechargeable battery
  • Timekeeping accuracy
  • Durability
  • Eco-friendly

Solar panel

Every solar watch comes with a solar panel. The panel is an integral component of the watch that is responsible for capturing the sunlight. This light is then converted into electrical energy which enables the power delivery to the watch. The solar panel in a watch is usually located on the face/dial of the watch and in some cases on the bezel.

Power reserve indicator

Most solar-powered watches feature a power reserve indicator, which helps indicate the amount of charge left in the battery. This feature is beneficial for those who wear their watch regularly and to ensure full charge in their batteries.

Rechargeable battery

The electrical energy generated by the watch is stored in what’s known as a rechargeable battery. This battery is what powers the functionality of the watch.

Most solar watch batteries last for several months or even years on a single charge. The lifespan of these batteries will depend on the watch’s features and frequency of usage.

Timekeeping accuracy

One of the things that solar watches are known for is their high accuracy. When it comes to timekeeping, these timepieces are known to showcase incredible accuracy, which adds to their popularity and demand.

Many solar-powered watches use a radio-controlled time synchronization feature, which enables the watch to always maintain accuracy to the second.

Another important feature that defines a good solar watch is its durability. Solar-powered watches are designed to be water and dust resistant, and to also protect it from other environmental hazards. This is what makes them ideal for outdoor activities such as camping, hiking and even swimming.


Lastly, another important feature of solar watches is that they are very eco-friendly. A Sun powered watch is able to achieve the title of being eco-friendly watches since they do not require a disposable battery.

Disposable batteries contribute to environmental pollution. Therefore, by using solar power, these watches help reduce the carbon emissions and also promote sustainability.

Eco-Friendly Watches: Timepieces of the Future

Solar is one of the technologies that will continue to grow in popularity, especially as more people become conscious about the environment. Watch enthusiasts are looking for sustainable alternatives to traditional watches like quartz or mechanical.

While Sun powered watches offer multiple benefits, such as being eco-friendly, needing low maintenance, and being cost-effective in the long run, they also have some limitations. For instance, solar-powered watches may not work efficiently in areas with low light, this could immediately limit their usefulness, which is a huge drawback.

Features of Solar watch

Besides that, solar watches need a technology that cannot be implemented on high-end luxury watches. It is due to the fact that those watches are always made from either full steel or gold, neither of which will complement the solar setup. On top of that, implementing such technology will also mean that these top luxury watch brands will have to take a huge risk. The fans of these brands vouch for their intricate movement as well as bold designs. Hence, it is highly unlikely that we will see any sun powered watches from top brands in the near future.

Having said that, technology continues to evolve and new innovations are being introduced every year. Therefore, it is exciting to see what the future holds for the world of watches.
