It's probably not the first thing that comes to mind when you think about what you can do to live a more eco-friendly life. A solar-powered watch can help you reduce your carbon footprint because it won't require battery replacement for at least 30 years.
Simply put, solar-powered watches work by converting light energy into electronic energy. To do this, the watch uses a specially designed photovoltaic system like traditional solar panels.
Underneath (and sometimes on top of) the translucent face of the watch is a solar panel, which induces an electric current when light strikes it. This electric current stimulates the formation of "free electrons". This electrical energy is transferred to a battery inside the watch where it is stored. The energy is then slowly released from the battery to power the clock, and voila! Timekeeping by light!
If you see the word "quartz" in the name when researching a solar-powered watch, it means that the rest of the movement works just like a traditional quartz crystal. It keeps accurate time and beats at 1 beat per second.
Solar powered batteries do not require regular disposal. Thanks to rechargeable lithium-ion cells, they last for years.
The birth of the solar-powered clock
Solar-powered watches have become a favorable option for people who want to reduce their impact on the environment. Technology has improved so much over the years that watches can now be powered by both artificial light sources and natural light.
The first sundial was developed in 1972 by inventor Roger Riehl (Roger Riehl). He built his prototype just two years before release. The watch was named Synchronar and had an unmistakably recognizable futuristic design for its time. As such, it has been called "space age design". The time indicator was placed on the side of the case to make room for the two solar panel units located at the top of the clock. The Synchronar watch, which became one of the longest running watches in watchmaking history, only ceased production in 2007.
The next solar-powered innovation was the Citizen Crystron model, introduced in 1976. It had an analog display, which allowed for a more classic design (it was the first solar-powered watch). At the time, it was one of the most expensive watches in the brand's catalog. This development marked the beginning of 20th-century solar-powered watchmaking technology and was the basis for the revolutionary Eco-Drive series. Over the years, solar energy has evolved significantly, expanding well beyond timekeeping into diverse applications. Today, solar power plays an essential role in providing renewable, eco-friendly electricity through technologies like solar panels and solar generators, contributing greatly to a more sustainable and greener future.
Advantages
One of the most significant benefits of owning a solar-powered watch is not having to replace batteries. Traditional clocks require frequent battery changes, which can be inconvenient and costly over time. However, in a solar-powered watch, the battery is charged by sunlight, so there is no need to worry about running out of power or replacing batteries frequently. This makes them a more economical option in the long run.
It is an eco-friendly alternative to traditional watches. Rechargeable batteries reduce the amount of hazardous waste generated by disposable batteries that can harm the environment.
In addition, solar-powered watches are known for their accurate timekeeping. Unlike traditional watches, which can lose or speed up time over time, solar powered watches utilize quartz movement technology to ensure accurate timekeeping.
Another advantage of solar-powered clocks is that they have a longer lifespan than traditional clocks. Since they do not require frequent battery replacement, they can run for several years without the need for maintenance.
Finally, a solar-powered watch is convenient for outdoor activities. They are designed to absorb sunlight and store energy, which means you can take them anywhere, including camping, hiking, and other outdoor activities.
Disadvantages
Here are some of the most common ones:
- The initial cost may be higher than traditional watches.
- Limited availability of styles/designs.
- Requires sufficient exposure to sunlight to maintain charge.
- Possible malfunction when exposed to extreme temperatures or moisture.
