  • Water-resistant up to 330 feet

10 Best Solar Atomic Watches For [year] [Top Reviews] 7

  • Atomic timekeeping

Excellent power charging

On a single charge, this watch can last for 10 months, even if it hasn’t been exposed to light after the fact (e.g, if it’s been left in a dark drawer). This is a wonderful improvement over other models of solar watches, some of which won’t even last for a day if it’s not being continually charged, let alone for months and months on end. Moreover, because you’ll be wearing the watch (it’s a great choice for everyday wear), you will get it recharged all the time.

Always have the perfect time

A full auto-calendar is included, and the day can be displayed in 12- or 24-hour formats. The stopwatch measures one hundredth of a second, and the countdown timer ranges from 1 minute to 24 hours, with increments either lasting for one minute or one hour.

10 Best Solar Atomic Watches For [year] [Top Reviews] 9


  • Durable and shock-resistant
  • Mute function
  • Water-resistant to 200 m
  • Can last several months on one charge 

Well-lit design

This watch has been designed in such a way that you will always be able to know what time it is. This is because the EL backlight ensures that you will always be able to see the face—simply tilt your wrist in lower-light conditions, and the watch will automatically adjust its display so that you can see the time—and also because of its large face. In addition, the font is easy to read, and the numbers are large enough so that you can easily read them. In the case of the EL backlight, this functionality is particularly ideal for using it at night-time.

Ideal design

Solar power lasts for a long time

With this model, once it has been fully charged, you can get charged on the watch for months at a time—even if you don’t continually charge the watch every day. Even if you keep it in a dark space that isn’t exposed to light at all—such as a dark drawer in your closet—the charge will still remain, and you will be able to use the watch even if you haven’t used it in a while.



How Do Solar Atomic Watches work?

Like other solar-powered devices, solar watches work because they are powered, in whole or in part, by a solar cell. Also known as photovoltaic cells, solar cells function by converting sunlight, or solar radiation, into energy, and then converting it into electricity, which—in the case of watches—is used to power the battery contained in the watch. The solar panel is usually located behind the crystal, and the dial may either be on the layer above the solar panel, or on the solar panel directly. Photovoltaic cells have significantly increased their capacity and strength since solar watches were first introduced in the 1970s.

Otherwise, solar watches work like other types of timepieces; they tell the time, and, depending on the model, might have other functionalities. Such functionalities include alarms, timers, stopwatch functions, and even the hour in other time zones. Also, like standard-powered watches, solar watches may be analogue or digital, and then some types may even be a hybrid of the two.

Things to Consider When Buying Solar Watch

If you’d like to buy a solar-powered watch, then there are definitely several things you’ll need to take into account. After all, you wouldn’t want to go into this search unprepared; you need to know what you’re looking for—at least a general idea—and, of course, how you’re going to find those models. Naturally, the first place you might look is on the Internet; in that case, don’t neglect the online reviews, since they can be a veritable goldmine of information. However, don’t be afraid to ask your jeweller or electronics-store employees for help. Workers like this have a lot of experience in dealing with solar watches, and they will be able to help you find exactly the watch that you’re looking for.

  • Do you like the style and colour?

If you’re going for a solar watch, then you shouldn’t simply settle for the first watch that appears to match your criteria. On the contrary, you need to make sure that you like the style and the fashion of the watch. How do you like the design? Is it too large, too small? Remember: a watch whose bracelet or strap too chunky or too skinny might not necessarily be appropriate for work, depending on what your workplace is like, and how lax they are on uniform regulations. What about the design? Is it too simple, or is its conflagration of squares, screws and accents too intense for you? And finally, do you like the colour? Because if you don’t like the colour, you might simply end up not wearing it.

  • How does it feel?

One of the most important considerations for when you’re getting a watch—any watch—is how it feels against your skin. Is it comfortable? If you’re wearing it against your bare skin, do you feel the beginnings of pressure markings beginning to form on your wrists and, if so, do they hurt? Does it go to the right level of tightness or looseness, or do you feel that you need to keep adjusting it so that it fits comfortably? Don’t neglect comfort and texture of your solar watch; these can have an incredibly important impact on how you wear the watch—and whether or not it’s right for you.

  • Can you close it easily?

A big part of wearing a watch is opening and closing it. In the case of the watches you’re considering, what or their clasps like? Are they easy to close and open, or difficult? If it’s difficult to open such clasps, you might simply find yourself wanting to wear that particular model of watch less and less, until you find that regrettably, you’re not using it at all.

  • How does it charge itself?

Naturally, a solar-powered watch will charge itself on solar power, but some models can also be charged normally, In cases like this, you’ll want to ask yourself whether you’d prefer a model that can also be charged regularly (i.e., by changing the batteries). The latter option might be preferable if you live in a colder area, where there isn’t as much sunlight (and, consequently, less access to bright sunlight that will power your watch). In other words, using a hybrid watch will provide you with an additional “safety net,” in the event that something goes wrong and your solar watch won’t work ideally in those conditions.


Final Verdict

If you’re in the market for a solar watch, then you should definitely consider the models that we have mentioned in this article. However, if you look into them and find that they’re not quite what you’re looking for, don’t despair; the perfect, ideal watch is surely somewhere close on the horizon. As long as you know what you’re looking for—as long as, in other words, you take into account those considerations that we’ve mentioned above—then you will definitely find the perfect watch for you and your needs. So, best of luck in your search; we know that—if you do your homework, and research properly—you will find the watch that’s perfect for you with no trouble at all.
