Solar powered smartwatch

We are starting our list with the latest solar-powered smartwatch from Casio called Casio Solar Edifice. It might look like a regular G-Shock or Casio watch but it also comes with several smart features.

It ensures that solar energy is not being wasted and used efficiently throughout your day.

This smartwatch is also perfect for motor-sports enthusiasts as it comes with a tachymeter. Using a tachymeter dial available on the watch you can measure the speed of a vehicle just by using the watch. If you are passionate about biking then this watch will definitely complement your riding gear like a Bluetooth helmet with a camera, protective gear, etc.

The watch can also store up to 100 laps on the watch itself therefore you can time your laps on the race track, swimming pool, or wherever you want.

Since battery backup is a priority for you Casio Solar Edifice comes with a power-saving function. This watch automatically goes into the power-saving mode in dark and disables watch hands as well as the watch’s screen.

Talking about the durability of the smartwatch, it is water-resistant up to 100m and also comes with scratch-resistant mineral glass on the watch face.

Overall, it’s a great solar-powered smartwatch from Casio that can be charged using solar energy, is durable, and also comes with several other important features. So do give this watch a look if you are looking for a tactical and rugged-looking smartwatch under $200.

2. Garmin Instinct Solar

Garmin Solar Smartwatch

Garmin is a well-known name in the world of smartwatches. Their watches are perfect for multi-sport tracking, fitness and activity monitoring, and more. The Instinct series from Garmin is made purposely for outdoor adventurers so you bet they have a solar-powered smartwatch for you. Allow us to present to you Garmin Instinct Solar which is a solar-powered outdoor smartwatch.

The entire watch face on this smartwatch has photovoltaic cells built into it. To simply put these cells convert solar energy into electrical energy. However, it should be noted that the corners of the watch face are operating at 100% photovoltaic capacity and the rest of the watch at 10% capacity. What it means is that the corner of the watch can utilize 100% of the solar energy it has been exposed to but the rest of the display can only utilize 10% energy.

With Garmin Instinct you get inbuilt solar widgets like Solar Intensity that allows you to track the smartwatch’s exposure to the sun in the last 6 hours. It also tells how intense the sunlight was while hitting the watch. The higher the intensity of sunlight hitting your watch the more charged it will get and vice versa.

Besides that, it is also a full-fledged multi-sports watch that can effectively track your sports activities like swimming, running, biking, hiking, etc. The watch sports ABC (Altimeter, Barometer, Compass) sensor that makes it perfect for hiking and other outdoor activities. Altimeter sensors measure your present elevation level, a compass is used to tell you the direction and a barometer can warn you of any potential storms.

If outdoor adventure is not really your thing then you can use other smart and health-oriented features of the watch. This smartwatch comes with multiple health tracking features like heart rate tracking, sleep monitoring, stress tracking, and more. It can also sync notifications from your smartphone to the watch screen making it fit for daily usage.

On a closing note, we would say this is the best entry-level Garmin solar smartwatch you can go for if you don’t have the budget for spending on expensive smartwatches.

The Good
  • Notification sync
  • Inbuilt GPS
  • Sports and activity tracking
  • Heart and sleep tracking
The Bad
  • Doesn’t support Garmin Pay

3. G-Shock Move

Casio solar powered smartwatch

Over the years people have formed this perception that G-Shock doesn’t make any smartwatches. If you are one of them let us introduce you to the Move lineup of sports smartwatches from them.

This watch comes with solar charging support therefore you can charge your smartwatch using solar energy as well as indoor fluorescent lighting. And if G-Shock’s claim is to be believed then this watch can operate in Time mode on solar power alone. In Time mode along with obviously reading the time you can also track your steps, and sync notifications from your smartphone. If you can keep this watch under fluorescent lightning for 8 hr every day and in sun 2hr a week then you won’t need to charge the watch again.

As the name suggests watch is targeted towards users who are always on the move. If you are one of them then this watch can track your sports activities, fitness activities along with your overall well-being. Since this smartwatch also comes with a heart rate tracker you can set your heart rate range, see a graph of your heart rate trends, set minimum and maximum heart rate, and do more.

Besides that, it also has an inbuilt training function for athletes. Using that you can track your pace, distance covered, calories burned, whether you have achieved your daily target, etc. G-Shock Move can also monitor your VO2 max, do analysis for running activities, and track your fitness level. However, to get the best out of this solar-powered smartwatch you need to install G-Shock Move app on your Android or iOS device.

Furthermore, the watch also has a built-in GPS, Compass, Thermometer, and Barometer. The barometer is especially useful if you are outside fishing or trekking as it can detect any sudden changes in atmospheric pressure and help you avoid sudden storms.

We don’t think we need to tell you about the durability of G-Shock watches but it is still worth mentioning that it is water-resistant up to 200m and features a shockproof design.

Although the watch is more expensive than other solar-powered watches on this list, it features advanced tactical features that make it worth it.

The Good
  • Can also be charged using indoor lighting
  • Bluetooth connectivity
  • Heart rate tracking
  • Sports activity tracking
  • Inbuilt GPS
  • Can work without charging in time only mode

4. Garmin Fenix 6 Pro Solar

Garmin Fenix 6 Pro Solar

If budget is not an issue for you then we would recommend going with Garmin Fenix 6 Pro Solar. This is the most advanced solar-powered smartwatch that you can buy right now. Garmin Fenix series is made for outdoor adventures and multi-sports activity tracking.

Just like Garmin Instinct Solar this watch also features photovoltaic cells in the watch. Hence, it would automatically start charging when exposed to sunlight. It also comes with a solar widget that allows you to see the intensity of the sunlight reaching the watch. To illustrate, if a watch is placed directly under the sun then solar intensity would be higher, and the watch would charge faster. However, if you are sitting under the tree or inside your home then solar intensity would be lower, leading to less or negligible charging.

Garmin Fenix 6 Pro Solar is almost double the price of the Garmin Instinct because of several smart features not available on the Instinct lineup. With this smartwatch, you can make contactless payments using Garmin Pay. Just add your debit or credit card and make payments anywhere, anytime without your smartphone.

Furthermore, this smartwatch comes with a music support function. Meaning you can use apps like Spotify, Amazon Music, and others to listen to your favorite tracks on the go. But you need to have a premium account of these services to listen to or download music on the smartwatch itself.

Besides that, this watch supports multiple navigation systems so instead of only supporting GPS it also supports GLONASS and Galileo navigation systems. This ensures that you get satellite signals even in the remotest corners of the earth.

Whether you are running, climbing, cycling, or doing any other activity it is important to keep a check on your vitals. That’s why this watch comes with a Pulse Ox sensor, Heart rate tracker, Sleep tracking, and more.

Moreover, it also comes with an incident detection feature that is similar to Apple’s Watch series fall detection feature. If the watch detects that you have experienced a hard fall during an outdoor activity then it will automatically send messages to your emergency contacts with the location.

To conclude we would say this is the best solar-powered smartwatch as it offers in-depth workout and sports analysis along with other important features.

The Good
  • Garmin Pay
  • Music Playback support
  • Multiple navigation system support: GPS, GLONASS, Galileo
  • Sports and Vital tracking
The Bad

5. Casio Pro Trek PAG-240 Series

Casio Pathfinder

This watch from Casio is part of their Path Finder watch lineup. It is made for all the explorers who like to go on a hike, trek, or other similar activities.

Casio Pro Trek PAG-240 comes with a solar cell built directly on the watch face. So, whenever you are outside under the sun would automatically charge itself. Moreover, according to Casio, the watch can run up to 6 months without being exposed to sunlight which is great for people who live in cloudy conditions.

The watch also has ABC sensors: Altimeter, Barometer, Compass. The barometer function on the watch can be extremely useful if you like to go fishing or hunting in mountains. As atmospheric pressure can easily fluctuate in these locations causing sudden rain and storm. However, if your watch is equipped with a barometer sensor you can focus only on the fun as it alerts you about an upcoming storm in advance.

Sometimes while having fun we can lose track of time but thankfully Casio Pro Trek PAG-240 series comes with inbuilt sunrise/sunset data. Therefore you can find a good camping spot or get back to the shore before sunset.

Since the watch sports a resin strap it is perfect for adventures as it is a highly durable material that can withstand some extreme pressures. Moreover, this watch is also water-resistant up to 100m so you even wear the watch while swimming.

One common complaint that we hear from most users is that G-Shock-like watches are hard to read in dark. You have to press the light button on them, again and again, to read the time in the dark. However, you won’t have to do this with this watch as it comes with auto illumination, and the watch automatically lights up the display by moving the wrist.

In conclusion, it is a great solar-powered smartwatch available at a reasonable price. However, this watch doesn’t support any Bluetooth connectivity and has no fitness tracking features so choose accordingly.

The Good
  • ABC sensors(Altimeter, Barometer, and Compass)
  • 100m water resistant
  • Multiple alarm function
  • Battery level indicator
The Bad
  • No smartphone connectivity
  • No fitness or smart tracking available
