How We Picked

Just like the technology that drives them, solar watches are always evolving. Looking for signs of recent updates or minor design changes are often a good indicator that the manufacturer had the opportunity to infuse the watch with the best materials for this generation of watches. Still, there are some tried-and-true solar watches that were designed right the first time and don’t need a lot of sophisticated updates to prove their value.

Of course, watches are a broad category appealing to different interests. There are also men’s, women’s and even a few unisex solar watches that have very similar features. With many of these, the design cues are the only definitive difference.

Some watches are geared toward certain interests and niches. These tend to have special features like a built-in compass, an altimeter, a barometer, or a timer/stopwatch. Just bear in mind that the more special features a watch has, the higher the price tag is likely to be.

Take the time to sit down and think about the features you are most likely to prioritize. This will help you spot the things you are most likely to use.

If you swim, snorkel, or free dive, you certainly will want to look for a rated dive watch. This essentially means that the seals and fasteners have been tested to withstand the atmospheric pressure of the stated depth.

If you are an outdoor enthusiast, you might want to look for a watch that has features like a compass, barometer, altimeter, or thermometer.

Durability is also a factor with many solar watches. Most people want a watch that can take endure a little bit of wear and tear. Some level of waterproofing is also nice. The last thing you want is to have a surprising summer downpour take your watch out.

It’s also worth noting that solar watches are not just for men. In fact, there are many manufacturers who offer high-quality women’s solar watches. These units are specifically designed to look stylish and comfortable on the wrist, yet have some of the functions that women want in a solar watch.

Buyers Guide

Modern-day wristwatches have evolved from the simple timepieces that our grandfathers used into stylish statements that make you look and sometimes even feel good. The problem with these units is that they usually rely on batteries to power the mechanical or digital parts.

When these batteries start to run low, they gradually lose the ability to keep accurate time. With some of these “Old Fashioned” watches the decrease in accuracy is miniscule, and often hard to notice over the course of a few days.

Even when you do catch the problem in time, the only solution is to buy more, often-costly, replacement batteries. As time goes on, they will eventually lose charge and need to be replaced. Leaving you in a constant costly cycle.

Fortunately, modern technology and materials have continued to evolve in ways that make it easier than ever to solve the watch battery problem. One of the most popular and effective is solar-powered wristwatch.

These units have rechargeable long-life batteries in them, that are directly connected to a small solar cell built into the watch. As you go about your day it collects solar energy which is then diverted to the batteries to power the mechanical aspects of the watch. Recent advancements in battery and solar cell technology allow these watches to run for extended periods of time, even when natural sunlight isn’t available.

There are a few things you want to look for when considering a solar-powered wristwatch, that go beyond simply how it looks or fits with your personal style.

Technology and Age of Design

Solar cell and battery technology continue to evolve, often at a rapid pace. The newer you’re the design of the wristwatch and its components the more likely it is to employ the latest tech advancements. This doesn’t necessarily apply to how long it’s been on the shelf, rather when was the last time the manufacturer refreshed or updated the design specs for the particular watch.

Sometimes this information isn’t available. Still, you can bet that any time a manufacturer is putting extra energy into marketing messages about their “New” technology, that it is likely near the forefront of what is possible today.

Materials and Durability

There are some materials that are obviously stronger than others. Stainless steel tends to be very popular with many solar watches. Some are even paired with super-strong, lightweight titanium. These watches tend to stand the test of time, enduring daily wear and tear.

Yet you shouldn’t discount silicone watches. Modern technology and manufacturing techniques have made silicone stronger than ever before. Many people also find that silicone watch bands are more comfortable than stainless steel, link, or titanium bracelets.

So, don’t let silicone or resin put you off of considering a specific watch. These materials are far more comfortable on the wrist today than they were even a decade ago.

Closures and Clasps

There are several different ways to secure a watch band or bracelet. Each can impact how the watch feels on your wrist, and some are a matter of personal preference.

A deployment clasp essentially unfolds into three sections or thirds. This degree of expansion is usually sufficient for most people to fit their hand through the band. You then collapse it down to secure it over your wrist. Many of these closures include some type of small hook-type latch.

A push-button deployment is similar to a more traditional deployment clasp, except it has buttons on each side of the clasp. You then pinch them to release and expand the band. The nice thing about this type of clasp is that it generally won’t accidentally open on its own. Still, some people complain that it can pinch your skin if you aren’t careful.
A deployment clasp with a safety basically folds over the closure section for added security. This type of clasp is more popular with a metal band or bracelet watches.

A hidden butterfly clasp looks like a seamless band at a casual glance. Except that it has a special type of push-button release mechanism that keeps it securely on your wrist.

A tang buckle is a little bit like a miniature belt. It has an adjustable closure with a single pin that is designed to fit into one of several holes in the band.

A jewelry clasp is essentially a simple latch that can be snapped or closed around a solid metal bar. You can easily release it by lifting the clasp and then disconnecting it from the bar.

Water Resistance or Waterproofing

Just like you, your wristwatch can be caught in the rain, or that accidental push into the swimming pool at a family gathering. In times like this, you don’t want to go into an immediate panic about the state of your watch.

For some, a water-resistant watch or one that is described as being “Splash Proof” might suffice. Though it would be nice to have a watch that is rated to be waterproof to a 1-meter depth, just for the times when you might accidentally drop it into water or it gets excessively wet.

Some high-quality waterproof watches are capable of being submerged to up to 100-meters. If you like to go swimming, snorkeling or surfing with your watch, you might want to prioritize one of them.

Anglers and sport fishermen might also want to prioritize a watch that is truly waterproof to at least 1-meter, rather than just on that is water-resistant. Beyond accidentally dropping it into the water, a watch that isn’t waterproof can still be damaged by frequently sticking your hand into the water to retrieve a fish or submerging it into a baitwell.

Special Functions and Features

Smartwatches are also taking the marketplace by storm these days. They do appeal to a certain segment of people who want to take sophisticated functions with them on their wrist instead of via their smartphone. There are also health watches and fitness bands that monitor basic biological functions. These devices deserve their own category and delineated special features.

That’s not to say that solar power watches don’t have special features. Some of the more popular options that you might want to look for include things like stopwatch functionality, multiple time-zone displays, or an LCD display face.

Outdoor enthusiasts might also be interested in things like a built-in barometer with altimeter, basic compass, or a thermometer.

Style and Design

The overall look, style, and design are often an appealing factor that draws people to solar-powered watches. Take the time to think about your personal style, as well as some of your favorite wardrobe items, and factor that into your choices. While it might sound simple, keeping your own personal taste in mind will go a long way toward preventing the dreaded “Buyer’s Remorse.”

Warranty and Protection Plan

If you are going to invest in a solar watch, you want it to be able to stand the test of time. With most watches, you will notice a manufacturing problem within a day or two of taking it out of the box. What a warranty, satisfaction guarantee or protection plan really tells you, is that the manufacturer believes in the long-term material quality and design of their product.

At the same time, there are some online retailers who sell their own affordable 3 or 4-year protection plans. This can be great insurance for times when you might find a watch you love, but it has a weak warranty.

Frequently Asked Questions

Q: Does A Solar Watch Need Sunlight?

A: Technically any significant source of light can affect the solar cell. This includes indoor lighting like the fluorescent lights you often find in most office spaces. However, the charge will be slow and natural sunlight still remains the best option for charging the internal solar watch batteries.

Q: Does the Season Effect How Well The Solar Cell Charges?

A: Natural sunlight is always the best option for recharging a solar watch. The stronger the source of light the more charge the solar cell imparts to the rechargeable batteries. This means that the weak sun of winter produces less charge than the strong sun of the summertime.

It’s also worth bearing in mind that in cold conditions, people are more likely to wear long-sleeve shirts, and coats. When the solar cell is covered by clothing it can’t generate charge and could cause the internal batteries to run low.

Over the course of a single day, a coat sleeve or a sweater won’t impact the charge of a quality solar cell with a rechargeable battery. In fact, some of the newest solar watches can go months on a single full charge. Just be mindful of it during the wintertime, and you likely won’t notice a problem.

Q: Will My Solar Watch Stop Working In The Dark?

A: The overall life of the rechargeable batteries is long enough that they can endure a full night on your dark nightstand. In fact, it would take several days if not weeks for the average rechargeable watch battery to run too low to keep accurate time. Some high-quality solar watches can even keep accurate time for months after a full charge.

Q: Are Atomic and Motion Charge Watches More Accurate?

A: When it comes to timekeeping mechanical and digital components can have an impact. Over a long period of time, atomic and motion charge watches are technically more accurate. However, this is still generally within a few seconds over the course of several months if not a year.

Q: What Is Overcharge Prevention?

A: Just like any other batteries, the rechargeable batteries in a solar watch can be overcharged. When this happens excess heat and other factors can start to degrade the battery’s long-term charging capacity.

In all honesty, this type of feature is really only going to come into play if you have a job where you are outside all day working in the sun with your wrist exposed. A long summer day at the beach could also potentially lead to overcharging the batteries, but if it only happens every once in a while it won’t cause major damage.

Since it’s a relatively new advancement, an overcharging prevention system is really telling you that the design is recent or updated from a previous model. This ultimately means it’s more likely to employ the highest possible technology and materials for this generation of solar watches.

Conclusion

Modern-day solar watches are a synergy of function and technology blended with stylish design. Every few years battery and solar cell technology managed to evolve a step. In time these innovations find their way into consumer electronics. Keeping an eye out for updated or new designs is a great way to make sure you are close to the state-of-the-art for this generation of watches.

When shopping for a solar watch, take the time to consider the features that you will use the most. Waterproofing or water resistance is always a nice touch to keep your watch from being damaged by rain or accidental splashes. Just keep in mind that you will need a true dive watch that’s rated for a great depth is you want to do more than simply snorkel or swim while wearing it.

Material selection can be a factor, especially if you want a watch that will match your personal style. Stainless steel, titanium, leather, resin, and silicone are some of the more popular options to consider. Factor them with your wardrobe and where you intend to wear it.
