Solar powered watches find themselves at the unique intersection of sustainable design and cutting-edge technology.

Powered by the sun, a solar watch doesn’t rely on a battery to operate – making this type of watch an incredibly reliable (and heirloom quality) timekeeping piece.  Furthermore, their reliance on solar technology will give you a unique watch that many others will likely envy.

Here are a few standout watches that are well-made:

1. Best Overall: Citizen Eco-Drive Atomic Timekeeping Solar Watch

Add this Citizen watch to your collection with their Eco-Drive Atomic Timekeeping Solar Watch.

Citizen is known for their immense quality and that’s exactly what you get with this Japanese quartz movement timepiece. The strap is a titanium link bracelet that locks with a solid fold-over clasp that is reinforced with a double push-button closure.

The quality is also shown through its impressive 42 millimeter-thick titanium case that comes with an anti-reflective sapphire dial window.

As great as this watch looks, it really is all about the subtle, chronograph displays. As a matter of fact, there are three small chronograph displays on the dial and includes one featuring a unique, radio-controlled chronograph. This chronograph means that if you are in any one of the abbreviated cities (i.e. LAX is Los Angeles), this watch will automatically be synchronized to a time zone broadcasted by a radio transmitter connected to an atomic clock.


  • Reliable Japanese quartz movement
  • Features Citizen’s reliable Eco-Drive
  • Automatically adjusts to multiple time zones with precise atomic timekeeping

With this watch, Casio combines supreme affordability (under $40) with functional utility with our pick for the best cheap solar watch, the Casio Solar Sport Combination. Casio solar watches in general are solid and affordable, but this one stands out.

This sports watch features Casio’s patented Tough Solar power and comes with a rechargeable battery that holds a charge for up to 10 months without further exposure to light.

This Casio solar watch has a distinctly sporty feel with its all-black design and round dial shape. The reason it’s a combination watch is that it offers both an analog and digital display. The time is displayed with a three-hand analog movement and the date is displayed digitally.

Speaking of the time, the hands and markers are neo-brite luminous hands which means you’ll be able to read the time at night. You can also program five daily alarms, plus a digital stopwatch and two countdown timers.


  • Inexpensive
  • Lengthy 10-month battery life


  • Not suitable for formal or professional settings
