Best Solar Watches

Solar watches are my personal favorite “type” of watch.

My first solar powered watch was a Citizen Eco-Drive that I bought in 2010 and I still wear it regularly. I have never done any maintenance to that watch and it works flawlessly.

The watch does have a battery, but the battery is charged by light. So it’s not like a normal watch battery that you need to replace regularly.

While sunlight does charge the watch more quickly, indoor light charges the watch as well.

No maintenance. Charge in sunlight or indoor light. Charging is free! Years of trouble free service. This is what you get with a solar powered watch.

The Best Solar Watch Brands To Purchase

The market for solar-powered watches is growing exponentially with a variety of brands. Below are some of the prominent names that you should not miss:

Casio

We are all familiar with this brand, right?

Casio is the first manufacturer to produce solar watches. Its brand name stands for quality, and the solar series is not an exception. Casio solar timepieces work excellently and charge themselves with even the faintest light source around.

Seiko

Seiko introduced its first solar watch in 1977. Shortly after, its GPS solar watch that could adjust the time based on your time zone came into being.

Seiko thrives to ensure you are satisfied with every purchase from the brand. Its products are all high-quality and durable.

Citizen

Few can compare to Citizen watches in terms of reliability. Thanks to the light-powered technology named Eco-Drive, you never have to replace the battery of any watch of the brand.

However, you may find Citizen watches slightly more expensive than their competitors. Based on my personal experience, it’s worth it.

10 Best Solar Watches For 2020

#1 G-Shock Rangeman GW-9400 – Best Choice Overall

G-Shock Rangeman GW-9400
best solar watches

Topping our list today is a product by Casio. Belonging to the G-Shock series, this candidate offers outstanding performance and long-lasting service.

G-Shock watches are famed for their tough construction, and this Rangeman is no exception. Made of stainless steel with shock resistant technology, the watch is certain to withstand grueling conditions. 

No need to take off your timepiece before joining outdoor sports now!

The water-resistance of the unit is also impressive. In particular, it can operate underwater up to 200m (660ft), making it suitable for recreational scuba diving.

We cannot fail to mention the Triple Sensor, which measures altitude, barometric pressure, temp, and compass direction. 

Pretty cool, right?

It does not stop there; the watch is capable of displaying sunrise and sunset data, measuring elapsed time, recording time, etc.

With all thes features, however, is the watch difficult to use?

Not at all! There are cylindrical buttons around the face, which take you directly to the sensor screen once they are pressed. You will know which mode you are entering without looking at the watch thanks to the audible tone.

Compared to other G-Shock models, this Rangemen is nearly twice the price. However, it is totally worth your investment.

Pros

Cons

  • Fairly large design
  • Not inexpensive

#2 Citizen Watches Men’s BM8180-03E – Best Value For Price

Citizen BM8180-03E
best solar watches

Next on the list is a Citizen solar watch, Model BM8180-03E.

This Citizen watch comes in a stylish and youthful design, making it suitable for your active lifestyle. 

The model is constructed from stainless steel, featuring a stitched canvas band that is available in two color options. There is a buckle closure for you to adjust the length.

This design is lightweight and feels great on your wrist. Actually, you hardly notice any pressure while wearing the watch.

The watch face consists of a three-hand analog display and a date window. Japanese-quartz movement is applied for ultimate accuracy. And of course, the watch charges itself in natural or artificial light with Eco-Drive technology.

This Citizen watch, however, cannot beat the above G-Shock Rangeman in terms of water resistance. It is only water-resistant to 100m, or 300ft, which is enough for snorkeling or swimming, but not diving.

The manufacturer guarantees this model with a five-year limited warranty, so you can buy with confidence. However, because of the good quality, it is unlikely that the watch will be need repair.

This unit is not without drawbacks, however, and most of the complaints are related to luminosity. Based on our experiences, we found that it was acceptable, but certainly not outstanding.

Pros

Cons

  • Poor luminosity

First off, this model, the BN0151-09L, looks stylish in dark blue. The round watch features a blue dial with date window and luminous hands.

However, the date window is rather small, so reading the date might be challenging.

What To Consider When Buying The Best Solar Watch?

best solar powered watches

Features

Along with solar power, solar watches come with a bunch of advanced features to give you the best experience ever.

For example, there is a quartz movement for improved accuracy. Some brands even equip their products with power-saving features to extend the runtime of the battery.

If you find manual time setting tedious, consider the atomic timekeeping feature, which allows the watch to adjust the time automatically.

Design

Solar-powered watches come in a variety of designs for you to choose, from sleek and elegant to formal attire. Let’s buy the one that fits your taste.

There is more about the design. Of course, you want the watch to look good on your wrist, but it should be user-friendly as well. Pay attention to practical aspects, for example, the watch face.

Fit

Your desired watch should fit your wrist nicely for ultimate comfort. Aside from the timepiece itself, the band will determine the fit. Make sure you like the style and material of the band. 

Steel bracelets allow length adjustment, while leather or fabric strap needs a buckle or clasp.

Water Resistance

This is a useful feature that you should look for in a watch, especially if you expose your watch to water regularly.

Some solar watches are merely splash resistant, which means the devices are resistant to a small amount of water only, such as a light drizzle or careful hand washing.

Meanwhile, others are built to function well underwater without sustaining any damage. There are different levels of water resistance; before jumping to buy a watch, make sure to check out the product details.

Materials

Material plays a significant role in determining the overall durability of the watch. 

Stainless steel or resin are widely popular materials due to the outstanding toughness. Steel is slightly heavier, but it offers a sophisticated look for the watch.

Price

Solar powered watches are available at many price points. All of the watches and brands above are excellent, and some are quite inexpensive.

However, if you can afford a bit extra, do not hesitate to go for high-end watches, particularly for additional water resistance or a feature that you need.

Frequently Asked Questions

What is a solar-powered watch?

As its name might already suggest, a solar-powered watch is a watch powered by sunlight or artificial sources of light. Therefore, the watch is almost constantly charged unless placed in a dark place like a drawer or box. Wearing a solar watch will save you the expense and hassle of charging a watch or buying new batteries.

How do solar watches work at night?

Of course, the watch cannot charge itself in complete darkness. However, it still works properly thanks to the rechargeable battery cell inside. 

Depending on different brands, the storage capacity can hold enough power for the device to function for at least 30 days on a full charge. Citizen Eco-Drive watches can run for 6 months on a full charge, even in complete darkness.

What are the differences between a solar watch and an atomic solar watch?

You can tell that the difference lies in the “atomic”. While a solar-powered watch requires a manual setting, its atomic counterpart adjusts the time using radio signals from the atomic clock in America. Cool, right?

How does the solar-powered watch charge itself?

There are solar panels around the watch face, which will absorb the light to power the timepiece. For more information about charging the item, refer to the manual guide.

Can I charge the watch under fluorescent light?

The answer is definitely yes!

Your watch will get power from any light source, and fluorescent and incandescent light are no exceptions. However, it takes longer to charge the watch with artificial light than with sunlight.

What should I do for better accuracy?

Do not worry! Solar watches are pretty accurate, and time lagging rarely occurs. Accuracy is even added with atomic watches, due to its working principles stated above.

How should I care for my watch band?

Maintaining your watch band is essential, but it depends on the specific type of watch band you own.

For instance, you are advised to clean the stainless steel bands regularly using a damp cloth. Say no to vinegar, as it will may damage the metal parts of the unit.
