Best Solar Atomic Watches
1. Casio Men’s G SHOCK Quartz Watch with Stainless-Steel Strap Model: GST-S110D-1ADR (G604)
- Tough solar powered , shock resistant; neobrite, 200-meter water resistance, double led light, world time, stopwatch, countdown timer, 5 daily alarms
- Hourly time signal, hand shift, battery level indicator, power saving full auto-calendar, 12/24-hour format, button operation tone on/off, regular timekeeping
- Quartz Movement
It features a digital display rather than an analog one, which in mind at least, makes it quicker and easier to read. You can tweak the time as you please to have it in either 12 hour or 24 hour format.
At the same time, it also displays the day and the date. This is quite the handy little feature. When you’re on vacation for example you can lose track of the days without a calendar.
In addition to its regular resetting of the time for absolute accuracy, it also has 4 daily alarms including a snooze alarm. To be honest, I think it’s really handy to have more than one alarm per day, I use mine to remind me to take my medication.
It also has a 1/100 second stopwatch, and countdown timer. The latter is particularly handy if like me you haven’t got a timer on your stove.
And talking about handy functions, there’s also a backlight, so you can read it in the dark or in low light. And a battery power indicator and battery saving function. And talking about battery life, if it’s packed away for 9 months without being powered by light, it should still work when you take it out of the box.
It’s stainless steel construction means that not only will it not rust, but it’s actually shock resistant to boot. So rugged and durable. It’s even water resistant up to a whopping 200m, meaning you could even wear it swimming and it won’t get damaged.
It’s worth noting at this point that Amazon sometimes has really good deals on this particular watch, so if you’re not in a rush for it, it’s well worth periodically checking the site for a good deal.
As for customer feedback, it’s been overwhelmingly positive. On the Amazon page for example, over 80% of customers (out of well over 1000) rated at an impressive 5 full stars out of 5.
Casio G-Schoock Pros:
- Good, wear-anywear look

It has all the other usual good qualities of a Casio watch, such as a stopwatch, countdown timer, power-saving function, and backlight.
The digital display is easy to read and can be displayed in 12 or 24 hour format. And it can bring up world time, which is handy if you need to check in with someone in another corner of the globe.
As for the look, it sports a very large rotating bezel which really stands out against the digital dial and black resin band. It’s a watch that demands to be noticed and rightly so.
It’s water-resistant up to an impressive 200m, meaning you can safely take it fishing or for water sports without the worry of it getting damaged at all.
If you like the sound of this watch, it’s worth keeping an eye out for deals, as sometimes Amazon has $100 knocked off the list price.
Speaking of Amazon, we noticed again that over 80% of Amazon customers who bought this watch have rated it a full 5 stars out of 5. And that’s after well over 400 individual customer ratings.
Casio Pro Trek Pros:
- Great watch for the outdoors

It also has those other great digital watch features such as alarms, world time, countdown timer, and stopwatch. And there’s a battery power indicator, and power saving function.

Buying Guide with Answers to your Most FAQs
What’s the difference between a solar-powered watch and a solar atomic watch?
Whilst both these types of watches are powered by small solar panels, a solar atomic watch is different in that it sets its time using a radio signal that’s broadcast from the nearest solar powered atomic clock in order to set and rest the time, keeping the watch time consistent.
In the US, this clock is at the Fort Collins building of the National Institute of Standards and Technology, based in Colorado.
How does a solar-powered watch work?
The solar panel on a solar wristwatch converts light, from any available light source, into electrical energy, which is then stored in a rechargeable cell, which can then go on to power the watch.
Does a solar-powered watch still work when it’s dark?
Once charged, the watch’s rechargeable cell will keep the watch powered and ticking over in the dark right through the night. In fact a solar watch’s power reserve is so long that you can keep it packed away for up to 6 months (sometimes longer), and when you get it out it should still work.
What to look for in a solar atomic watch
In terms of their ability to power up from light, and their ability to accurately present the correct time, solar atomic watches are pretty much the same, and the remaining factors to look for in the watch, are those that apply to any watch.
These are the appearance, the functionality, the brand, the price point and the toughness.
Now, appearance comes down to personal taste. And although the watches on our Top 5 picks are marketed as men’s watches, we think some of them may well appeal to women too. The ones with the resin bands look very sporty, but the one with a stainless steel band would even suit as a dress watch.
The brand is a significant factor. In choosing our Top 5 picks we didn’t deliberately intend to focus on Casio’s offering, but just picked out the best ones on the market. But to be honest, Casio is a world-class brand for a reason, having been in the business for so long and producing watches of such great performance. If you did want to look at another brand to compare, then you should check out Seiko.
When it comes to price, you can get a good solar atomic watch without having to break the bank, and several watches in our Top 5 picks come under the $100 mark. However, if your watch is intended as a status symbol, then it’s down to you whether you want to pay accordingly. But no one’s really going to know how much your watch costs you unless you tell them.
A good solar atomic watch can offer far more in terms of functionality than merely giving you the time. This is where watches can really come into their own. Here are some features that we feel every good digital watch ought to have: the date, a timer, a stopwatch, and at least one alarm.
Some watches even feature world time, which can be handy for some people but perhaps not for everybody.
Where solar atomic watches can offer further functionality is in their battery power indicator and their battery saving mode. These are features worth looking out for.
With regards to how tough and durable your watch needs to be, that comes down to how and where you intend to use it. Whilst dress watches need some level of durability, there some watches, such as the some of Casio’s watches from their G-Shock range that we have covered. Our Top 5 picks, that offer superior toughness and are not only shock resistant, but are also sufficiently water resistant for use in water sports.
Hi, I am Charles your local Home Tech and Gadget Expert. I’ve been fascinated with electricity for as long as I can remember. I grew up in an old home in a rural setting, so the quality and continuity of our electrical service were spotty at best.
Spending time without power (or running off a generator) gave me a lot of appreciation for the benefits of electricity. I love writing and talking about it.
