Best Solar Watches

Citizen Eco-Drive Chandler Field Watch

Model: BM8180-03E
Case size: 37mm

Citizen solar military-style watch with green canvas

Citizen’s Eco-Drive is the king of solar technologies in watches. Therefore, starting the list with a Citizen timepiece is almost a must. 

The Chandler Field Watch BM8180-03E, as the name suggests, is inspired by the military and fits perfectly for those with an active lifestyle. The silver-toned 37mm stainless steel case along with an army green nylon strap defines its ruggedness. 

Another characteristic adding to the looks of a classic field watch is the black dial with Arabic numerals and a day-date feature at 3 o’clock.

The watch is powered by a 3-hand E101 Eco-Drive solar quartz movement which receives energy from all sorts of light; even the dimmest of lights will give the rechargeable battery the required energy it needs to function. When fully charged, the cell can last up to six months without any light. 

When you’ve found yourself in the dark and in need of a time update, the luminous hands and markers will help you in that. You can also swim, snorkel, and shower with the watch on your wrist as it is water-resistant up to 100m (330ft).


✅ Rugged and durable
✅ Keeps an accurate time
✅ Doesn’t require battery replacements
✅ Is powered by any light


❌ Luminescence could be better

Seiko Prospex PADI Solar Watch

Model: SNE435P1
Case size: 44mm

Seiko piece as one of the best solar watches

Another highly renowned brand in the field of solar technology is Seiko. Although the brand’s main competitor Citizen boasts a higher number of solar-powered timepieces, Seiko has nevertheless provided a stiff rivalry in the Seiko and Citizen comparison.

Seiko Prospex collection comprises timepieces for Air, Land, and Sea but the most sought-after are their dive watches.

The Seiko Prospex PADI Solar, which also features on our list of the top Seiko watches, has very sophisticated apparel, and though aimed for professional diving, it fits well to other occasions too. The prime element contributing to the versatile look is the above-average 44mm steel case and band. 

The blue dial is covered with Seiko’s proprietary Hardlex mineral crystal and features a distinctive red minute hand and a date display with a magnifier. The unidirectional bezel on the outer ring, as well as luminous hands and markers, give the timepiece the look of a genuine dive watch. 

However, the practicality of a diver’s wristwatch is guaranteed through a 200m (660ft) ISO-certified water resistance and screw-down crown and case back. 

Seiko’s solar cells can maintain the charge for up to 10 months while keeping excellent accuracy.

❌ Too large case for old-school wearers

Tallying the list of Japanese watch companies providing solar charge is Casio’s G-Shock line. It has become a synonym of ruggedness while offering top-notch technologies at the same time.

The GW2310 Atomic Solar watch comes with two high-tech features – besides solar power, it also features atomic time. The solar atomic watch comes with Multiband 6 technology, which guarantees atomic precision through radio waves in six locations – Northern America, the UK, Germany, China, and Japan (2 locations). 

The fully digital GW2310 comes in a durable resin case with a 41mm diameter. You can expect this timepiece to look big on your wrist as the width at 15mm is well above the market average. The knurly knobs, which also add to the dimensions, serve the purpose of protecting the watch from unwanted knocks and hits, making it utterly shock-proof for rigid activities. 

The watch comes with an EL backlight and stands water pressure up to 20 ATM. Last but not least, the stopwatch measures a fantastic 1/100th of a second, in that outperforming many of its main competitors.

Especially supporting the latter are the brass case and leather strap that provide the kind of durability one would expect from a timepiece carrying the name “Expedition Scout.” 

Although Timex’s solar charge lasts less than the majority of competitors’ equivalents – about two months – it is still more than adequate for a convenient user experience. 

The grey dial with distinctive greenish hour markers is the prime characteristic of the watch. You can be sure to receive positive feedback when wearing it.

However, the best part of this watch is definitely the solar-powered feature. When typical smartwatches last a couple of days before needing a charge, this Instinct Solar will last up to 54 days in smartwatch mode. The dial has an indicator on the dial showing the remaining energy, so you’ll know precisely when it needs a charge. 

When it comes to the applications, you’ll have a wide variety of them available. GPS, heart rate monitor, stress tracking, and altimeter are just a few to mention.

The watch also makes it a perfect solar military timepiece due to being constructed to U.S Military Standard for thermal, shock, and water resistance to 100m (330ft).

FAQ About Solar-Powered Watches

As promised, we’ll answer some pervasive questions that many people face in searching for a solar-powered timepiece. 

Q: What Does Solar Mean on a Watch?

A: A solar watch is a timepiece that converts all sorts of light into electric energy. The light is absorbed through a solar panel under the crystal and then converted to electrical energy, which eventually powers the watch.

The surplus power is stored in a rechargeable cell and is used when the light’s not present.

Q: What Is The Best Solar-Powered Watch?

A: Determining the best solar-powered watch is difficult due to the different expectations and points of evaluation. But what is certain is that it is from either Citizen, Seiko, or Casio.

Citizen’s Eco-Drive technology is the most widespread, while Seiko Solar has the best selection of solar dress watches. Casio’s Tough Solar, on the other hand, is the best choice for extreme conditions.

Q: Are Solar Watches Better Than Battery?

A: Yes, solar watches are way better than typical battery-powered wristwatches.

When a regular timepiece requires battery replacement every 1-3 years, then a solar watch recharges its cell constantly when the light is present, eliminating the need for a new battery. Hence, the convenience is on a whole new level.

Q: Do Solar Watches Last Forever?

A: Apparently not. Although rechargeable batteries last a very long time compared to typical disposable batteries, their charging capacity will degrade due to long-term use. It is said that a typical solar cell needs a replacement after every 10-15 years.

Q: Can You Overcharge a Solar Watch?

A: No, you can’t. A solar watch has an overcharging prevention function that automatically activates to prevent the battery from being charged further.

Conclusion: Best Solar Watches

Solar power is one of the handiest functions in a watch. Not only it provides ultimate convenience, but is also eco-friendly, with a good reputation, and is available for a very affordable price. The best solar watches come primarily from renowned brands – Citizen, Seiko, and Casio.

Recent times have seen some other watch manufacturers join the list. For instance, the likes of Tissot, Timex, and Garmin have earned great feedback for their solar watches. Therefore, a watch from the said brands is definitely a good fit.
