Needless to say, its battery gets charged when you take it out in the sun. However, the thing that amazes me is its battery life of 22 days in solar mode. And the fact that it is not in a battery saver mode but in a smartwatch mode is just amazing. Therefore if you do long trips and do not like to charge your watch often then Garmin Fenix 7 Solar is the watch for you.

3. 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. 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 allow 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 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 to spend on expensive smartwatches.

The Good
  • Notification sync
  • Inbuilt GPS
  • Sports and activity tracking
  • Heart and sleep tracking

5. G-Shock Move GBD-H2000

Casio solar powered smartwatch

Did you think that Casio only makes normal watches? If you did, then you couldn’t be more wrong, because the fifth watch on our list, is the Casio G-Shock Move GBD-H2000. Do not let its look fool you, because this is a full-fledged activity-tracking sports smartwatch with loads and loads of features.

This G-Shock Move GBD-H2000 is a solar-powered smartwatch. That means that you won’t have to worry about recharging it. This watch can be recharged under both solar light and indoor lights. It needs about 8 hours of indoor light a day or just 2 hours of sunlight a week, and that is enough to keep it running.

Being a G-Shock means that is it pretty much assumed that this watch is shock-resistant, which it is. This watch also features a water resistance of 200 meters, which is insanely impressive considering this is a smartwatch. These specs easily make it the best rugged solar watch.

Apart from the basic functions, this watch features GPS and Bluetooth connectivity along with heart rate monitoring. If you are someone like me who is adventurous and likes to go hiking, camping or just traveling in general, then this watch can be a great companion for your journeys.

Aside from the basic stuff, the G-Shock Move GBD-H2000 smartwatch has an optical heart rate sensor, accelerometer, gyroscope, pressure sensor, magnetic sensor, and thermo sensor. These 6 sensors along with the GPS on this watch ensure real-time activity and health tracking. You can get accurate data regarding your heart rate, distance covered, speed, time, calories burned, and more.

You can measure 8 different activities using this watch like swimming, running, biking, gym workouts, and more. Not only that, the G-Shock GBD-H2000 also provides great sleep tracking and blood oxygen level measurements.

6. 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 after Fenix 7 Solar 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 a 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 in 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. This means 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
  • Expensive

7. Casio Pro Trek PAG-240 Series

Pro Trek PRG-340

This watch from Casio is part of their Pro Trek watch lineup. It is made for all the explorers who like to go on a hike, trek, or other similar activities. The Pro Trek PRG-340 is one of the best solar-powered smartwatches by Casio. These watches are eco-friendly as they are made using eco-friendly bio-mass plastics, so they also fit their tagline (one with nature).

This solar-powered smartwatch is not an average smartwatch with solar charging. The Pro Trek PRG-340 is powered by tough solar, which means that not only sunlight but also the average fluorescent lamps and other light sources can charge up this watch. Also, this watch has an energy-saving feature, which blanks out the display when it is left in the dark to save power. You can go anywhere you want without worrying about charging or your watch going dead.

This Pro Trek PRG-340 comes with triple sensors, an Altimeter, a Barometer, and a Thermometer alongside a digital compass. This watch is made for adventures, therefore, it has all the essential tools you may need while traveling, camping, or on a hike. With its built-in sunrise and sunset time display, you can plan your adventure accordingly and get back to your camp before it gets dark.

The barometer function on the watch can be extremely useful if you like to go fishing or hunting in the mountains or the wild. As atmospheric pressure can easily fluctuate in these locations causing sudden rain and storms. 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.

You also won’t have to worry about it being wet or submerged in water as the PRG-340 comes with 100 meters of water resistance. The watch also has a rotating bezel and a super illuminator, which ensures optimum visibility even in low-light environments.

All in all, it is one of the best solar watches you can get in 2024. However, you should know that this watch does not support Bluetooth connectivity and fitness tracking.

3. Battery Life And Charging

Solar charging is a great feature to have but ensure that the watch can also be charged through some other power source so you don’t have to only rely on the sun’s rays. Furthermore, it is also important that the watch offers a decent battery backup on a single charge.

Tom Nielson

Tom's love for watches started when his grandfather gifted him his Rolex watch when he turned 18! Being a teenager it was a big deal for him. Later when he got his first job he bought Fossil Palm Pilot back in 2003 which was a smartwatch. Since then smartwatches have come a long way and so is Tom's love for them. His experience with watches inspired him to start Wearholic and share his knowledge of wearables including watches, smartwatches, smart glasses, & smart clothing.
