Many people are interested in solar watches because they are powered by renewable energy. Solar watches use a solar cell to convert light into electrical energy, which is used to power the watch.
These watches are designed to have a long battery life, and many can last for years without needing to be replaced.
But do solar watches need batteries? Let’s dive straight into the answer.

Do Solar Watches Need Batteries?
Solar watches do not need batteries, as they are powered by the sun. However, they may need to be replaced after a few years of use. Solar watches are more costly than battery-powered watches, but they are more environmentally friendly and will last longer.
Solar watches that use traditional batteries will also need to have the batteries replaced periodically. Solar watches that use rechargeable batteries may require more frequent charging, but they will not need to have the batteries replaced as often.
Ultimately, the type of battery used in a solar watch is a matter of personal preference.
Benefits of Solar Watches
Let’s take a look at some of the benefits of solar watches.
Durability And Water Resistance
Solar watches are very durable and water-resistant, making them ideal for everyday wear. They also tend to be more accurate than traditional watch movements, because they are not affected by temperature changes or gravity.
For example, the Citizen Eco-Drive watch is water-resistant up to 200 meters and has a five-year warranty.
Solar watches are an excellent choice for anyone who wants a reliable and low-maintenance timepiece.
Longevity And Efficiency
Solar watches are very efficient, converting light into energy with minimal loss. Even dim light will keep a solar watch charged. And because solar watches don’t have batteries, they don’t suffer from the battery drain that mechanical and quartz watches do.
Reliability And accuracy
Solar watches are environmentally friendly because they don’t use batteries. Watchmakers like Seiko and Citizen make high-quality solar watches that are accurate to within seconds per year.
How long do solar watches last?
The amount of power that a solar watch can store will determine how long it will run in the dark. Most solar watches can store enough power to last for several months without being exposed to light, but some high-end models can last for years.
Solar watches are very convenient because you never have to worry about batteries, but it is important to keep them exposed to light on a regular basis in order to maintain their power reserve.
On average, solar watches last between two and five years before they need to be replaced. And because they don’t have batteries, they are more environmentally friendly than traditional watches.
How do solar watches work?
Solar watches use a solar cell to convert light into electrical energy. The solar cell is made of two layers of semiconductor material, usually silicon. When light hits the solar cell, it knocks electrons loose from the atoms in the silicon.
The electrons will then flow through the cell and into an electric circuit, where they are used to power the watch. The solar cell is usually hidden beneath the watch dial, so you can’t see it.
Solar cells are very efficient, converting about 15% of the light that hits them into electrical energy.
Do they need the sun?
Solar watches need to be exposed to light in order to charge. But they don’t need direct sunlight, and they will even charge indoors.
The amount of light that a solar watch needs to function varies depending on the model, but most solar watches can be charged with just a few hours of exposure to light per day.
Are solar watches better than battery-powered watches?
Solar watches are more costly than battery-powered watches, but they are more environmentally friendly and will last longer. Solar watches that use traditional batteries will also need to have the batteries replaced periodically.
Solar watches that use rechargeable batteries may require more frequent charging, but they will not need to have the batteries replaced as often.
How long does it take to charge a solar watch?
To charge a solar watch, you need to put it in direct sunlight for at least 12 hours. The amount of time it takes to charge a solar watch varies depending on the type of watch and the amount of sunlight it is exposed to.
Most solar watches will be fully charged within 1-2 days.
Different types of watches
It’s important to consider different types of watches before understanding solar watches.
Quartz
Quartz watches are powered by batteries and use an oscillating quartz crystal in order to keep time. They are the most accurate type of watch, but the batteries need to be replaced every 1-2 years.
Mechanical watches
Mechanical watches are use a spring to power them that needs to be wound periodically. They are less accurate than quartz watches, but they don’t require batteries.
Solar watches
Solar watches are use a solar cell to power them that converts light into electrical energy. They are more costly than quartz and mechanical watches, but they don’t require batteries and are more environmentally friendly.
What are the best solar watches on the market? (buyer’s guide)
There are lots of different solar watches on the market, but it can be difficult to determine the best ones. That’s why we recommend the following models:
- The Casio G-Shock GA100-1A4 is a tough and durable watch that is perfect for outdoor activities. It has a large face and is water-resistant up to 200 meters.
- The Seiko Solar SNE095P1 is a stylish and sophisticated watch that is perfect for everyday wear. It has a small face and is water-resistant up to 100 meters.
- The Citizen Eco-Drive AW1490-08E is a sporty and affordable watch that is perfect for active people. It has a large face and is water-resistant up to 100 meters.
What do you do when your solar watch stops working?
When your solar watch stops working, there are a few things you can do to try to fix it.
First, make sure that the watch is fully charged. If the watch has been stored in a dark place, it may need to be exposed to sunlight for a few hours before it will start working again.
You can also try resetting the watch by pressing the reset button. If none of these methods work, you may need to replace the battery. Solar batteries typically last for several years, but they can eventually lose their ability to hold a charge.
Replacing the battery is usually a fairly simple process, and you can find instructions in the watch’s owner’s manual.
Can a solar watch last forever?
Solar watches are powered by light, so as long as they have access to light, they will continue to work. However, the battery life of a solar watch can vary depending on the type of battery used and how much sunlight the watch is exposed to.
Additionally, the internal components of a solar watch may eventually wear out, even with proper care. As a result, solar watches will likely need to be replaced or serviced after several years of use.
While they may not last forever, solar watches are still an environmentally-friendly and low-maintenance option for those looking for an alternative to traditional battery-powered watches.
Final thoughts
Solar watches are a great choice for anyone who wants a reliable, low-maintenance, and environmentally friendly watch. They are more costly than battery-powered watches, but they will last longer and are more accurate.
Solar watches that use traditional batteries will need to have the batteries replaced periodically, but solar watches that use rechargeable batteries may only require charging more frequently.
Ultimately, the type of battery used in a solar watch is a matter of personal preference.
