13 Best Solar Watches: Divers to Dress

Long-lasting and eco-friendly, the solar watch is finally having its day in the sun (pun intended). That said, this particular sector is still arguably in its early stages compared to others in the men’s watch space, even if its history goes back longer than you might think. As more brands embrace the power of solar watches, however, one can expect them to proliferate accordingly. You still have plenty to choose from in the meantime, including an impressive number of Seiko solar watches. There’s also TAG Heuer‘s new solar-powered Aquaracer to consider, plus brands like Casio, Citizen, and Seiko. Here’s the best of the best modern solar watches.

Despite debuting during LVMH Watch Week earlier this year, we got our first real look at TAG Heuer’s inaugural solar-powered Aquaracer at the famed Watches & Wonders event in April, and it didn’t disappoint. It features a built-in solar module—aka Solargraph— and needs only two minutes under full sunlight to generate a full day’s performance from the TH50-00 movement. This one is made for the outdoors with the rugged design, DLC-coated steel case, and luminous markers to show for it. It will hit the market in October of this year (should everything go according to plan).

Solar-Power Watch Buying Guide

Looking at the concept from an outside perspective, solar-powered watches are an interesting addition to the horological segment. Generally, they use light energy to work, with a solar cell placed under the dial to convert light into electrical energy. According to watch experts, Watches2U, when these timepieces take in light, the solar cell changes into energy that is then stored in a rechargeable battery which works to power the watch.

How Solar-Powered Watches Work

Barring modern smartwatches (we can save those for another day), most traditional timepieces are either powered by mechanical movements or quartz movements. Mechanical watches generally take two forms—manual and automatic—both of which require a certain level of upkeep. Quartz watches employ a battery and basically run until that battery dies, at which point you can replace it or get a new watch. Both methods have their benefits, but one is fairly inconvenient whilst the other comes with an expiration date of sorts and is also somewhat wasteful.

With solar power watches, a new type of underlying technology enters the fold and brings some key benefits along with it. Inside each model is a small solar panel, which absorbs either sunlight or artificial light and then converts that light into energy. Compared to a traditional battery, a solar-powered battery can last about 10 years on average. And unlike mechanical pieces, there’s no need for winding the crown or getting the watch serviced once every few years. Long-lasting and eco-friendly, the solar watch is finally having its day in the sun.

What to Consider Before Buying a Solar-Powered Watch

As with all things in the world of modern products, your mileage may vary. Solar watches are certainly no exception and they run the full gamut of style, specs, and price points alike. Before taking the proverbial plunge, consider the following factors:

  • Movement – Solar watches are compatible with digital movements but the aesthetics touch down across the board. Whereas a mechanical-looking solar watch will dispense with a classical design language, a digital solar watch will tout robust construction and a host of functional features. Hybrid watches, meanwhile, tend to draw from both worlds by injecting subtle digital elements on an otherwise analog display.
  • Light Type – Importantly, with solar watches, the type of light used to power will differ greatly between sources. For instance, sunlight will charge your watch faster than artificial light, so always keep an eye on how much sunlight it is getting.
  • Light Intensity – Like the type of light, intensity will also impact your watch. A sunny day will improve charging compared to dull and cloudy weather.
  • Case Size – Solar-powered watches are no different from their traditional counterparts in that they come in various case sizes. If you want something slim and compact, stick with 40mm or less. Those who think bigger is better should go 42mm and up. Bear in mind that extra functions tend to yield larger case sizes, in general.
  • Price – Solar watches cover a wide spectrum of price points without veering into the upper stratospheres. You can score a Casio solar watch for as little as USD$30 whilst the new TAG Heuer Aquaracer Solargraph is expected to retail for just under 3k.

How Long Do Solar Watches Last?

One of the major concerns around solar watches is durability, however, it is important to recognise just how far the technology has come in recent years. Like the innovations seen in luminous watches, solar watches have developed extensively, most notably in the way they charge. According to UK business First Class Watches, solar-powered watches are almost always charging, meaning that the power reserve is only used when there is no light source.

“Some Eco-Drive watches have a power reserve of more than eight years, unless you’re planning on joining some civilisation who live in darkness underground – your watch isn’t likely to run out of charge,” they wrote. “This may not sound too great when you’re considering the reliability of a solar-powered watch, but it’s important to remember that the watches can last beyond 10 years depending on how you use them.”
