Reasons Why You Should Buy a Solar-Powered Watch
Most people turn to solar power for two common reasons: energy efficiency and environmental sustainability. When solar technology is applied to watches, most people notice that the watches are more reliable and durable.
Listed below are the common reasons why you should buy a solar-powered watch:
Accuracy and Reliability
The advantage of having a solar-powered watch is the fact that it can recharge anytime and anywhere as long as there is a light source. With improved technology, solar-powered watches can absorb both natural and artificial light. So you don’t have to worry if the sun is not constantly shining on your side of the world.
Since solar-powered watches are constantly charging, they can accurately tell the time. This makes them reliable. Solar-powered watches have outshined other types of watches like quartz, atomic, automatic, and mechanical watches.
Efficiency and Longevity
The advantage of being able to charge anywhere there is a light source makes solar-powered watches very efficient. Solar-powered watches have built-in rechargeable batteries that can store reserve energy for long-term use.
Whenever the watch is exposed to a light source, it will automatically convert it to energy and be stored accordingly. The life of a solar-powered battery can last for weeks or months without exposure to any light source. Your watch would signal an alarm to inform you that it needs to be charged. This signal is in the form of two-second increment movements in time.
Water- Resistance and Durability
Solar watches are durable. They are housed in high-quality and heavy-duty materials such as titanium and hardened crystal. Also, solar watches are durable because they are not prone to be opened for access to the battery or to wind to prevent them from stopping.
Solar watches are also water-resistant. Since you don’t have to open or need to manipulate the watch, the rubber gasket can protect the watch. The internal parts are protected from water penetration. This is a problem for other types of watches such as mechanical, quartz, and automatic.
Human waste has poisoned the environment. Because of this, many watch manufacturers are trying to do their share in non-polluting the environment. They have done their research to find the most efficient and eco-friendly power source for their watches.
Battery production and disposal cause a lot of carbon emissions and other harmful effects on the environment. Thus, it addresses these concerns, and the possible solution is to lessen the use and disposal of batteries. This is what makes solar watches great, they utilize rechargeable batteries!
How Do Solar Watches Work?
Solar watches take advantage of sunlight or artificial light sources for energy. They can store energy from the sun in their batteries. They can also function without batteries. They have built-in power reserves which allow them to be operational even at night.
Photovoltaic solar cells are arranged around the face of the watch and are responsible for absorbing light. If you decide to buy a solar-powered watch, it should be charged and ready to use. Most solar-powered watches can last for a few months before recharging. The package should include an instruction manual on how to charge your watch.
What You Should Know about Solar Watches
The first solar watch became very popular in the 1970s. The idea was first conceived in 1968 by Roger Riehl, an inventor. This achievement by Riehl was marked as a great advancement in the horological industry.
With many more improvements built upon the idea of Riehl, you are now seeing modern-day solar watches. The current solar watches are more advanced, durable, and efficient. They have better solar cells that are unrecognizably embedded on the watch’s surface and can accommodate all types of light sources.
Solar cells act like solar panels but on a small scale. Solar cells are also called photovoltaic cells. Solar cells are electric devices that are responsible for the conversion of sunlight or artificial light into energy. These are incorporated into the dial or bezel of the wristwatch to be able to capture as much light as possible.
Solar watches can still function at night or when in areas that are not well-lit because energy is stored in rechargeable cells. This power reserve is used by the watch to power itself when no light is available. Avoid leaving your solar watch in places where they have no access to light for a long time. This could drain their energy completely and leave them unable to recharge.
The great thing about solar watches is the fact that they can absorb and convert both natural and artificial light sources into energy that can be stored in the battery inside the watch. The upside of exposing your watch to natural light (sunlight) is that it charges faster and can give more power to your watch.
If you don’t have 12-hour access to sunlight in your location, don’t feel disheartened. You can still expose your watch to artificial light sources such as fluorescent lights or lamp shades. What is important is your solar watch is frequently exposed to light.
What To Look For In Solar Powered Watches
You want a watch that you can use for a long time. You want it to have features that you consider important for your everyday life. Listed below are some considerations you need to look into when buying a solar-powered watch:
The biggest consideration, by far, that you have to be mindful of is the kind of technology the watch has. Technology these days is constantly evolving. Your watch should be up-to-date with the latest for it to serve you well.
Most current watches do not only tell time. They also provide you with other information such as the date, atmospheric measurements, and even smartphone compatibility. Getting a solar-powered watch with a lot of features is what you should avail of today.
In making any kind of purchase, you should have a set budget for it. It would be impractical to buy an expensive watch and lose your life savings in one go. The best watch brands are expected to be expensive for you to get what you pay for.
If this is your first time buying a watch, do buy one that is within your budget. You don’t have to spend so much on your first attempt. There are several affordable solar watches that are of excellent quality but will not force you to break the bank.
A watch is an extension of you. Aside from your personal choice of clothes, your watch also describes your personality. Do you prefer a more classic and elegant watch? Or, do you want a bulky or colorful one? How it looks when you wear it should also be a consideration.
Look for a watch that is just right for the size of your wrist. You want to be comfortable with your watch; you don’t want it to be too big that it gets caught on things. If you are more comfortable reading a digital clock, then don’t buy an analog watch.
If you have an active lifestyle, you should invest in a quality water-resistant watch. You can wear it without worrying about ruining it. Without second thoughts, you can easily jump into water activities such as swimming, snorkeling, and scuba diving. It is best to own a watch that is water-resistant for hundreds of meters underwater.
Even if you are not a sporty person, it would still be advantageous if your watch is water-resistant. You don’t have to worry about the rain and how it could affect your watch. You can even dip in the pool without worries.
When buying a watch, you must break down what you need in a watch. Are you satisfied that it can only tell you the time and date? Would you prefer that it is packed with a lot of apps and features that you can use while doing outdoor activities?
If you are an outdoor enthusiast who enjoys camping, you should consider a watch that is packed with all the good stuff such as a GPS tracking system, timer, stopwatch, compass, thermometer, barometer, provides time zone information and can be connected to your email.
It is not enough for a wristwatch to be comfortable and durable. It should also have special features that are beneficial to use. It is great to own a watch that is packed with a lot of useful functions. Some functions that you may want your watch to have are a multi-time zone display, water-resistant, a compass, barometer, Bluetooth capability, and many more.
Aside from the multitude of functions your watch can do, it would also be great if the material it is made of is made from special material. There are watches made from titanium or stainless steel. There are displays made of sapphire crystals or hardened mineral crystals. It adds to the appeal if the dials also come in interesting colors like blue and gray.
Many people consider watches as investment pieces. Watches ideally should last you for years. It is a simple machine that you use every day and you expect that it will not bug down anytime soon.
High-quality watches are expected to last longer than poor-quality ones. However, not everyone can afford a high-quality watch. Go for a watch that is durable and at the same time within your set budget.
Most watches run on batteries. With the current advancement in technology, you can now enjoy solar-powered watches. With solar-powered watches, the light source is converted into light energy and stored in your watch’s battery.
Since your battery can be recharged using solar power; you don’t have to buy replacement batteries every time it dies. Minimal battery waste helps the environment. Several solar-powered watches have a battery life of more than one year without the need to recharge.
As much as possible, you should look for a watch that is comfortable and not burdensome to wear. A watch that is bigger than your wrist can make your hand feel weighed down. Aside from this, you would look awkward with a bulky watch on your small wrist.
You may consider plastic-made watches for these to be lighter. However, many prefer stainless steel watches because of their durability. If you are looking for durable watches, you should purchase those made from high-quality materials.
How to Take Care of a Solar Watch
The band of the watch is the part that needs a lot of maintenance and care to last longer. There are different types of watch bands. Each type has its particular set of maintenance instructions. For stainless steel bands, you can clean them using a damp cloth. Avoid using vinegar because this can damage your stainless steel band.
On the other hand, if your band is made of nylon, leather, or resin, these are prone to getting damp and smell bad due to wrist sweat. Allow these bands to completely dry before wiping with a cloth. Give your bands a quick clean every week to keep them in good condition longer.
Avoid exposing your watch to direct and intense sunlight. This could cause damage to other parts of the watch. If the battery needs changing, you need to bring it back to the manufacturer for proper maintenance.
