While enjoying the beautiful day and the outdoors, what happens if your watch runs out of batteries? Not good, right? You will face a lot of trouble in a hurry. That’s why solar watches are such a blessing. So, how do solar watches work?

Solar watches work by using a solar cell, which gets charged by the sun during the day. Simple as that.

The charge is stored in the battery cells and is used during the night to start your watch. This also saves the battery cells from getting drained out too soon.

Today, I will share what solar watches are, how they tick, and what they offer to us. So, let’s get started.

How Do Solar Watches Work | Everything Inside Out

As the name implies, solar watches use energy from the sun. They are the most cost-effective option as compared to normal watches, but they require sunlight to work. First, let’s look at the components first:


  • Solar Cell Holding frame
  • Solar cell block
  • Solar cell connecting spring
  • Solar cell support
  • Date indicator maintaining plate screw
  • Date indicator maintaining plate
  • Date indicator
  • Date indicator: Driving wheel
  • Date corrector lever
  • Date Jumper
  • Date corrector lever
  • Date jumper
  • Calendar platform

The working mechanism is pretty simple, really. You have the battery, ticking watch handle, and everything in between.

However, the watch has a solar panel on the face that collects sunlight and converts it into electrical energy. This energy is stored in a rechargeable battery inside the watch via the battery. The battery powers the watch’s movement, which keeps time.

Solar watches are very efficient and can run for years on a single charge. They are also very environmentally friendly because they don’t use any fossil fuels.

One downside of solar watches is that they can be a bit blurry sometimes due to variations in sunlight intensity throughout the day. Other than this, the watch works just fine.

What are the Benefits of Solar Watches?

One of the most important things in life is time. If you are looking forward to taking a solar watch, then you should know some benefits it has to offer. Here are a few benefits of solar watches:

1. No battery change is needed

The key feature of any solar watch is its ability to convert sunlight into electricity. There are several ways to power a solar watch, including photovoltaic (PV) cells and so on. Turns out, you don’t need to swipe the battery with a new one every few months.

2. Environmentally friendly

Solar watches use a clean, non-polluting energy source, i.e., the Sun. A solar watch powers a small battery, which keeps your watch running without a charge for several months. So no environmental damage.

3. Highly durable and last for years

When exposed to sunlight, solar watches work just like other watches. But in addition, the premium quality kicks in. You could say solar watches are better than other watches and will last at least 2 years more.

4. Tons of options to choose from

Solar watches are made from high-quality materials and feature many different designs and colors. It also has an anti-shock function and a shockproof function (For premium budget). So you can get the best watch in your hand.

5. Track activity

An active tracker provides you with a detailed view of the time of sunrise, sunset, and local weather conditions. This information can help to optimize activity times.

What are the Disadvantages of Solar Watches?

With every positive, there is a negative. Now, let’s see some disadvantages of a solar watch:

1. Low display quality in low sunlight

A downfall of the solar watch is found when it’s not charged properly. Or the sun doesn’t shine as bright. You may experience low display quality after a week of not charging the battery.

2. A bit expensive

The more expensive you go, the better quality you will get. If you can buy a more expensive watch, manufacturers can bypass any display problems by using more solar panels.

3. No automatic system

When the solar watch has batteries, it can save money, but it does not have an automatic system. It needs you to recharge it every day.

If you don’t put enough charge into the watch, it can run out of power. And the batteries will become depleted over time, making it harder and harder to use the watch even after a full recharge.

Frequently Asked Questions (FAQs)

Are Solar-Powered Watches Any Good?

Solar-powered watches are great for people who look for both durability and functionality. Also, you can keep it with you at all times without needing to worry about battery life. It’s one of the best out there in terms of quality, durability, and performance.

How Do Solar Watches Recharge?

Most solar watches recharge wirelessly. You just place them in the sunlight to collect energy. Once the power levels drop below the threshold, the watch automatically shuts off to prevent damage.

Do Solar Watches Need Battery Change?

Yes, solar watches need a battery change every few years in order to keep them running properly. The battery will need to be replaced more frequently if the watch is exposed to the outside elements because it will require less sunlight to produce enough power for operation.

How Long Do Solar Watches Last?

Solar watches are powered by light, so as long as they are exposed to light, they will continue to run. Most solar watches will last for several years before needing to be replaced. However, every 3 to 4 years, you will need to change the battery for better usability.

End Note

A watch powered by solar energy. Easy as pie, right? However, these solar watches need special technology in order to convert the sun’s energy into electrical energy.

They usually have small battery cells, which run the digital display, alarms, and other functions. You may need to replace them after a few years, depending on the user’s habits.

The output that the solar watch will provide is dependent on the solar panels that are used in it. A higher number of panels will increase the amount of energy that it can produce.

Rule of thumb, never leave the watch in the drawer, else the batteries will die out.
