Garmin - Instinct 3 Solar GPS Smartwatch 50 mm Fiber-reinforced Polymer Tactical Edition - Black - (2025)

I bought the Instinct 3 Solar 45mm to replace my old Venue 2. I really wanted something with more features, and I knew the solar charging would come in handy for the activities I like to do. I've only had it a short time, but I've taken it on a 3 day backpacking trip on the AT (breadcrumb feature saved my butt a couple times from making a wrong turn!), several horseback trail rides, running, rafting, cycling, hiking Medicine Bow Peak in WY (again, breadcrumb feature!! Love it), general camping and hiking. I love all the specific activities it accomidates. I've even used the torch feature. The solar charging is so so handy when your're out in the wilderness. The battery lasts forever. I'm really happy with this watch and plan to keep it for years to come! Btw I'm a woman with narrow wrists, but the watch fits me fine. That was something I was concerned about when I was deciding to buy this.

This was a gift for my boyfriend. He absolutely loves it! He appreciates the very long battery life, the charging capabilities through the solar cell, the flash light and the physical buttons on the bessel. Absolutely recommend for someone who hates charging a watch regularly but still want all the fancy smart watch features.

Great improvement from Apple Watch!!! I appreciate the ruggedness and durability as well as the battery life. The solar feature keeps my battery charged for two weeks. It is very easy to use for fitness tracking and gives much more in-depth and accurate information then Apple Watch and just using the Health app

This was not a planned purchase. Without warning my Garmin Forerunner 945 stopped tracking properly and the battery was draining extremely fast. The Garmin Forerunner 945 was a premium fitness tracker that was around $750 when it was released. I was very concerned that I would have to spend a premium price to get a comparable device. The Garmin Instinct 3 offered everything I was accustomed to and more. The watch has excellent gps sensors that accurate lock within seconds. The flash light has a strobe setting that is excellent for letting drivers see you during evening runs. The battery life is insane compared to previous watches I have owned. The only feature it doesn’t have, is the ability to program a multi sport workout that is a mix of running and strength training. But you can program a hot key and transition between activity profiles with the same workout. In short you cannot program a workout but you can accurately log a multi sport workout and edit the details in the Garmin App. There are more expensive Garmin watches out there but this one is an excellent model and I feel like it meets value and functionality perfectly.

Garmin Instinct 3 Solar — Better Than I Ever Expected I honestly didn’t expect these watches to be this good — but Garmin Instinct 3 Solar completely blew my expectations away. This watch is not about fancy animations or useless smart features. It’s about reliability, endurance, and truth. The battery life is insane — with solar charging, I almost forget what a charger even is. I wear it every day, outdoors, indoors, workouts, sleep — and it just keeps going. The build quality is rock solid. It feels like a real tool, not a toy. Scratches, cold, heat, sweat — it doesn’t care. This is a watch you trust, not one you babysit. Health and activity tracking is spot on: heart rate, stress, sleep, Body Battery — everything feels honest and consistent. No fake numbers, no drama. Just clean, reliable data that actually helps you understand your body. The screen is perfectly readable in sunlight, the buttons work flawlessly (even with gloves or wet hands), and the simplicity of the interface is a huge plus. No distractions. No nonsense. This watch feels like it was made for people who value freedom, durability, and independence. After using it, I can confidently say: Garmin Instinct 3 Solar is better than all my expectations — and easily one of the best watches I’ve ever owned. Highly recommended. No regrets. Zero.
