If you don’t like the inconvenience of changing your watch battery every now and then, you should opt to add a solar-powered watch to your collection. If you want to take it up a notch, why not choose a timepiece with atomic timekeeping?
The best thing about atomic watches is that you have access to accurate time at all times. Atomic watches are set to universal time and receive radio calibration signals for accurate timekeeping. This means that an atomic watch never needs to be adjusted as it’s perfectly synchronized with the US atomic clock in Colorado.
For today, we’ve made a list of the best solar atomic watch that you can get from the market. We’ve tested many solar atomic watches and these are the best of the bunch.

Best Solar Atomic Watch
1. Casio G-Shock GW9400 Rangeman
For many of our regular readers, the Casio G-Shock GW9400 Rangeman is no stranger. After all, it has been featured as one of the best G-Shock models especially for heavy-duty professions like EMT workers. As you can see, it’s also a Solar Atomic watch.
A Masterpiece of an Atomic Watch
The G-Shock GW9400 Rangeman is a fan-favorite as far as Casio’s Master of G Series goes and it’s not hard to see why.
The watch comes with the famous Triple Sensor feature which includes a digital compass, altimeter, barometer, and, thermometer. Combined with the watch’s excellent toughness, you have yourself a timepiece that will help guide yourself in places you’ve never gone before.
In terms of form factor, the GW9400 Rangeman features an irregular shape, even among other G-Shock models. However, it does feel great while wearing and sits nicely on the wrist. I’ve had this watch for the longest time and it only has very minor scuffs with no noticeable scratches. With such a performance, it’s not a surprise if this piece lasts for a good decade.
As far as battery life goes, I can only recall a few times that it needed to be recharged. Even then, I only needed to leave the watch for several hours and it will be charged. Lastly, the atomic timekeeping updates every night so it’s never an issue for me.
2. Casio Pro Trek PRW2500T
A fair warning to those who don’t like Casio watches: this list will feature a lot of them. With that said, the Casio Pro Trek PRW2500T is always a great choice for outdoor enthusiasts and active people. Plus, it’s an amazing solar atomic watch.
Feature-Rich Atomic Solar Watch
People who like their watches that come with everything under the sun will appreciate the Pro Trek PRW2500T. It’s simply packed with features that it can get overwhelming for some. This Pro Trek version is the improved iteration of the plastic PRW2500. The model featured is made from stainless steel and titanium.
The Multi-Band Atomic Timekeeping will ensure that your watch is very precise. It even comes with an auto-calendar feature that’s pre-programmed until 2099. It’s safe to say that you don’t have to worry about the time and date with the Pro Trek PRW2500T.
The Pro Trek PRW2500T is geared towards outdoor use so it also has the famed Triple Sensor feature. From what we have tested, the compass, altimeter, and barometer work at a functional level. The watch display allows you to get multiple information at a glance. However, it can get a little too busy for people.
Overall, the Casio Pro Trek PRW2500T is the best solar atomic watch in the Pro Trek series.
3. Citizen Eco-Drive Titanium Perpetual Chrono
On this list of the best solar atomic watch, the Citizen Eco-Drive Titanium Perpetual Chrono might just be the best-looking. However, it’s way more than just a classy, handsome watch.
High-Specced Atomic Timekeeping
Citizen’s Eco-Drive series features some of the best solar-powered watches money can buy. Among the impressive collection of watches, the Citizen Eco-Drive Titanium Perpetual Chrono stands out by having a great set of features and incredible design.
One of the first things you’ll notice is the lightweight profile of the watch. Thanks to the titanium case and band, the Titanium Perpetual Chrono feels just right despite being a fairly large watch. Besides, the watch is eye-catching but it’s not overdone or flashy. The dial looks cluttered at first but you’ll quickly appreciate just how well-done the layout is.
For some people, the design of the AT4010-50E Titanium is easily the main selling point. However, if you care about superior battery life, the Eco-Drive technology should drive the point home. With Eco-Drive, the watch is powered by light and not necessarily solar energy. Of course, this is an atomic watch which means that it employs radio-controlled function in multiple timezones for max accuracy.
Ultimately, the Citizen Eco-Drive Titanium Perpetual Chrono is not a cheap atomic solar watch but it’s highly recommended for fans of atomic timekeeping.
4. Casio G-Shock GW2310-1 Tough Solar
If you are looking for the best solar atomic watch that won’t make a dent on your budget, the Casio G-Shock GW2310-1 Tough Solar is an easy recommendation.
Best Value Solar Atomic Timepiece
I’ve bought the G-Shock GW2310-1 Tough Solar because I needed an atomic watch for daily use. This watch piece fits the bill due to its low price and that it’s a G-Shock. With that said, the GW2310-1 is impressive right out of the box.
This sub-$100 watch looks the way as you might expect. Its analog display isn’t exactly modern or timeless but it’s more than a functional watch with enough features to offer. However, many people should find the sporty design appealing.
Of course, it’s an atomic watch and I’m happy to report that it delivers in accuracy. The GW2310-1 is radio controlled and syncs daily with Colorado’s Cesium-133 atomic clock. The auto calibration works great, even after many years of use.
In terms of toughness, the GW2310-1 gets the job done. The watch is impact and shock resistant, and even comes with a 200M water resistance rating. Also, the battery life is excellent and can last up to 10 months with a full charge.
Ultimately, the GW2310-1 is a solid atomic solar watch that comes at a good price. Don’t sleep on this one!
5. Seiko Radio Sync Solar Coutura
Seiko is known for its tough and reliable watches plus the craftsmanship is hard to deny. The Seiko Radio Sync Solar Coutura is a fine member of Seiko’s lineup and it’s one of the best solar atomic watches that you can get.
Good-Looking Yet Heavy Watch
For starters, the Seiko Radio Sync Solar Coutura is a beast of a watch – it’s quite large and a bit on the heavy side. Despite the heavy weight, the Coutura feels weighty but not overly so. Also, despite the weighty profile, the watch feels comfortable to wear which is a nice surprise.
One of the best things about this watch is the striking blue dial. For starters, it’s a very eye-catching dial especially with its unique design and layout. Reading the time is easy and the sub-dials are very legible as well. My only complaint about the dial is that the date window is too small.
Of course, this is an atomic watch so accuracy is never an issue. With Radio Sync, the watch will automatically sync every night so you don’t have to set it anymore. The only time that you’ll need to set this watch is when you travel to a different time zone.
In conclusion, the Seiko Radio Sync Solar Coutura is the best solar atomic watch you can get from the infamous Seiko brand.
6. Citizen Eco-Drive JY8035-04E Navihawk
The Citizen Eco-Drive JY8035-04E Navihawk is an atomic solar watch for someone who wants it all. As you can see from the dial, it’s a watch that doesn’t leave anything to the imagination.
A Solid Atomic Watch With a Crazy Dial
The JY8035-04E Navihawk is not for minimalist fans. It’s an unapologetic sports watch that aims to give you all the information you need. In addition, the display is analog but there are digital readouts as well. It’s not the easiest watch to use and there’s a learning curve.
The Atomic Timekeeping feature means that you don’t have to set the watch ever again. I’ve been using this watch for years and the atomic feature works like a charm.
This watch is simply oozing with quality and craftsmanship. However, the band leaves a lot to be desired. In retrospect, I just wish that it’s more durable since mine broke after only months of use.
To sum it up, the JY8035-04E Navihawk is the spy watch that you’ve always wanted. In conclusion, the watch has some flaws but it’s still a solid atomic solar watch.
Atomic Timekeeping Done Right
That wraps up our list of the best solar atomic watch. Hopefully, we have helped you find an atomic watch that best fits your needs.
