10 Best Solar Powered Smartwatch 2026 in the United States

The Garmin fēnix 7S Pro Solar smartwatch excels in several key areas for a solar-powered smartwatch. Its solar charging capability is impressive, enabling the smartwatch to use the sun’s energy to extend battery life significantly, potentially lasting for weeks in smartwatch mode. This is ideal for outdoor enthusiasts and those who spend a lot of time outside. The 1.2” display is clear and functional, though some may find it small compared to other models. The watch is built to last with a 42 mm fiber-reinforced polymer case, steel bezel, and rear cover, making it durable and water-resistant, essential for various outdoor activities.

Fitness and health tracking features are comprehensive, including heart rate variability, Pulse Ox for altitude acclimation, and advanced sleep monitoring. These features provide a holistic view of health and fitness, suitable for serious athletes and health-conscious users alike. The built-in LED flashlight is a unique addition, offering variable intensities and strobe modes for nighttime training or general use. Compatibility with Bluetooth, Wi-Fi, and USB ensures robust connectivity options, making the watch versatile for different user needs.

The design is rugged yet stylish, and the 2.22-ounce weight ensures it is comfortable for all-day wear. However, the watch’s extensive features may seem overwhelming for casual users who might not utilize all the high-end functionalities. Additionally, the premium price might be a barrier for some potential buyers. In summary, the Garmin fēnix 7S Pro Solar is well-suited for outdoor enthusiasts, athletes, and individuals seeking comprehensive health and fitness tracking, though it may be overkill for everyday users.

The Garmin Instinct 2X Solar - Tactical Edition is a rugged GPS smartwatch designed for outdoor enthusiasts and those who value durability. One of its standout features is the solar charging capability; the Power Glass lens actually boosts battery life, giving you infinite usage in smartwatch mode with just a few hours of sunlight each day. This is great for users who may spend extended time outdoors without easy access to charging. Its military-grade durability means it can withstand tough conditions, including thermal and shock resistance, making it suitable for adventurous activities.

In terms of fitness and health tracking, this smartwatch doesn’t hold back. It offers comprehensive monitoring of heart rate, sleep patterns, and even advanced metrics like heart rate variability, which can help you better understand your recovery and training needs. There's also a variety of built-in sports apps that cater to activities like running, swimming, and strength training, perfect for those who are serious about their fitness.

There are a few elements to consider. While the solar charging is a major plus, the battery capacity is relatively low at 4 mAh, which might be a concern for users who prefer longer periods between charges without relying on sunlight. The 1.27-inch display, although clear, might feel small for those accustomed to larger screens. Additionally, while it has a robust design, it may not be the most comfortable option for everyday wear due to its thickness and weight. It’s important to note that while it offers a wealth of features, some of the health metrics may not be entirely accurate since it’s not a medical device. The Garmin Instinct 2X Solar is an excellent choice for adventurers and fitness enthusiasts who appreciate durability and advanced tracking capabilities, but it may not be ideal for those looking for a sleek, everyday smartwatch.

The Garmin Forerunner 955 Solar is a highly capable smartwatch designed specifically for athletes, particularly those into running and triathlons.

This is particularly beneficial for users who spend a lot of time outdoors. The always-on, full-color display is easy to read, making it user-friendly even in bright conditions.

On the fitness front, it offers a comprehensive range of health tracking features including training readiness scores, sleep analysis, and heart rate variability insights. These tools provide valuable feedback on your performance and recovery, helping you optimize your training plan. The built-in mapping features and access to multiple global navigation systems ensure accuracy in tracking your routes, which is a strong plus for runners and cyclists.

In terms of design, it’s lightweight, which adds to comfort during long workouts, but it’s important to note that if you prefer a more stylish watch for everyday wear, its sporty look might not appeal to everyone. Connectivity options like Bluetooth and USB are standard.
