It started as a budget-friendly alternative to Garmin’s premium watches, delivering great value at a fraction of the cost. But with the newest release, things feel different—not necessarily bad, but certainly different.

Garmin Instinct 3 Solar Review: – What’s Inside the Box
Unboxing the Garmin Instinct 3 immediately feels satisfying. Inside, you’ll find the essentials:
- The watch itself.
- Finally, a Type-C charger (yes, no outdated cables here!).
- A quick guide to help you get started.
It’s a no-fuss unboxing experience with just what you need to set up and start exploring.
Quick Overview of the Garmin Instinct 3 Series
The Garmin Instinct 3 series comes in three models:
- Solar
- AMOLED
- Essential
Each model caters to different user needs, from advanced features to budget-friendly options. However, the expanded features come with a noticeable price increase compared to earlier generations.
- Solar Model: Long-lasting battery life with solar charging.
- AMOLED Model: Vivid display for a modern look.
- Essential Model (Instinct E): Basic functionality for budget-conscious users.
Whether you’re looking for a long-lasting battery, a vibrant display, or something simpler, there’s an Instinct 3 model to fit different needs.
Why the Garmin Instinct Series is the Top Outdoor Smartwatch
The original Instinct was one of my favorite Garmin watches, primarily because of its value. It delivered many of the same features as the Fenix series but at a fraction of the price.
Back then, I could confidently recommend the Instinct to anyone wanting a reliable, multi-functional watch without breaking the bank.
Things are different now. The Instinct 3 is a much more advanced watch—and yes, it’s better in almost every way. But it also costs significantly more.
While the first-generation Instinct felt like an unbeatable deal, the new models require a closer look to decide if they’re worth the money. That said, the upgrades delivered here are hard to ignore.
The Price Increase: Do You Get More for Your Money?
The price jump from the first Instinct to Instinct 3 can be staggering, possibly three or four times higher depending on the model.
With that said, these newer models pack way more features. From better displays to increased battery life, the enhancements are obvious, but they come at a cost.
If you’re on a budget, the Essential model might seem appealing, but losing features like the flashlight might make it feel too stripped back.
At the same time, for outdoor enthusiasts or someone seeking a full-featured GPS watch, the Solar and AMOLED models might justify the price increase. It all comes down to what you need.
What’s New in the Instinct 3 Solar?
The Instinct 3 Solar keeps its rugged, practical design but introduces key upgrades to make it more competitive in 2023. Here are some of the standout improvements:
- Two size options: You can now choose between a 45mm and 50mm case to better fit your wrist.
- AMOLED display option: A higher-quality screen makes menus and data look better than ever.
- Longer battery life: Solar charging supports extended use, especially in smartwatch and GPS modes.
- USB-C charging port: After years of the same outdated charging cable, we finally get USB-C.
- Flashlight: What may seem like a gimmick is one of my favorite additions.
- Improved barometer placement: Early models had issues with barometer positioning, which Garmin has corrected here.
Aesthetic Upgrades: Prettier, But Not Perfect
Let’s be real: the first-generation Instinct wasn’t a looker. It had an almost bulky, utilitarian vibe that screamed: “I’m here to work, not to look pretty.” Instinct 3 improves on this.
While I wouldn’t call it a stylish watch, it’s easier on the eyes.
Garmin’s signature round display with a smaller inset circle remains, and while it’s not groundbreaking, it feels more refined here.
It’s still a rugged design, though, and if sleek aesthetics are a priority, this might not check your boxes.
Instinct 3 Solar Display: Memory Pixel vs. AMOLED
A big talking point with Instinct 3 is the introduction of an AMOLED display option. The AMOLED screen is vibrant, and colorful, and feels like a big leap forward visually.
The menus pop and the overall user experience is much improved in appearance compared to the older MIP (memory-in-pixel) screens.
However, MIP screens still have their appeal. They’re more efficient with battery usage, making them ideal for extended outdoor trips where charging isn’t an option. Here’s how they compare:
Memory Pixel Display
The memory pixel version is incredibly sharp and crisp. Text and visuals pop on screen whether you’re outdoors in sunlight or indoors. This classic option feels reliable and efficient.
AMOLED Display
The AMOLED version has a modern, vivid display, making it slightly pricier. However, it lacks one surprising feature: a touchscreen. This omission feels odd and somewhat limits its functionality for those drawn to AMOLED displays.
Overall, Garmin has improved display quality significantly compared to Instinct 2. The visuals are punchy, and even with the memory pixel display, it almost feels like there’s a backlight on all the time.
If you prioritize screen quality and don’t mind charging your watch more often, the AMOLED is the way to go.
Outdoor adventurers or anyone needing maximum battery life, however, will likely lean toward the MIP display.

GPS That Adapts (And Saves Battery)
Garmin stepped things up in the GPS department too. The Instinct 3 features adaptive multiband GPS, which balances accuracy with battery efficiency. How does it work?
- Open spaces: In areas with a strong signal, it reduces GPS pings to save battery.
- Challenging terrains: In dense forests or mountains, it ramps up tracking for better accuracy.
In my tests, the GPS locked on incredibly fast—less than two seconds outdoors. It’s even functional indoors, near windows, though naturally less reliable indoors.
When I tested it on a walk, its tracking impressed me with its precision. This is a big improvement over older Garmin watches.
If you’re an outdoor adventurer, GPS accuracy is non-negotiable. The Garmin Instinct 3 Solar stands out with its Multi-GNSS support (GPS, GLONASS, Galileo) and practical features like TracBack navigation, which helps you retrace your steps.
However, the lack of topo maps might be a dealbreaker if detailed mapping is crucial for you.
On the other hand, the Suunto 9 Peak offers solid GPS and topo map integration via the Suunto app. It even provides turn-by-turn navigation, making it slightly more user-friendly for trail running or biking routes.
That said, it’s sometimes slower to acquire GPS signals, which can be frustrating if you’re eager to get moving.
The Polar Grit X Pro delivers reliable GPS with Komoot-powered route guidance and specialized tools like Hill Splitter, which tracks ascent and descent.
While it’s dependable overall, it may not be as accurate as Garmin’s multi-band tracking, especially in dense forests or canyons.

Heart Rate Sensor: Same Old, Still Reliable
One area Garmin didn’t upgrade is the heart rate sensor. The Instinct 3 uses the same sensor found on the Instinct 2 and Fenix 7 models. It’s not Garmin’s newest generation sensor (like on the Fenix 8), which might disappoint some users.
However, in my experience, the sensor remains fast and responsive. Whether walking, running, or tracking resting heart rate, it delivers accurate data.
Garmin may have kept the older sensor to cut costs, but this is more than enough for 99% of people.
It’s much more reliable than some competitors—like the sensors on my Apple Watch, which often miss finer details.
Garmin Instinct 3 Solar Health Tracking Features
The Garmin Instinct 3 doesn’t skip on health features. It’s packed with tools to keep track of your fitness and overall well-being:
- Heart Rate & Resting HR
- Body Battery: A helpful gauge of your energy levels throughout the day.
- Stress Tracking
- VO2 Max and SpO2: Stay on top of oxygen levels and endurance.
- Advanced Sleep Tracking: Now with nap detection included.
- HRV Status and Training Metrics: Great for athletes monitoring recovery and performance.
Garmin has done a great job blending functionality for both everyday users and committed athletes.
Battery Life: Solar vs. AMOLED
One of the biggest upgrades with the Garmin Instinct 3 Solar is its battery life. Thanks to solar charging, it lasts longer than ever. If you’re someone who hates constantly plugging in their devices, this is a huge plus.
For most users, the difference in battery life between models makes choosing easier. If you’re sticking to short trips and urban environments, the AMOLED’s battery should be plenty.
But for multi-day hikes or expeditions, the MIP model is better suited to your needs. It’s worth noting that the 50mm versions offer slightly better battery stats due to their larger size.
Here’s how the battery life stacks up across different models:
| Model | Smartwatch Mode | GPS Mode |
| 45mm MIP | 28 days | 40 hours |
| 45mm AMOLED | 18 days | 32 hours |
| 50mm MIP | 40 days | 60 hours |
| 50mm AMOLED | 24 days | 40 hours |
Solar charging further extends battery life in outdoor environments, making the Solar models ideal for adventurers.
Flashlight: A Surprisingly Useful Feature
The addition of a flashlight might not sound game-changing, but hear me out—it’s brilliant.
Whether you’re on an evening walk, looking for something in the dark, or camping, the flashlight becomes something you’ll use daily.
After experiencing it, I can’t imagine going back to a watch without one. This is one feature that makes the Solar model a clear winner over the more basic Essential version.
Rugged Features and Durability
As with previous Instinct models, durability remains a strength. The watch offers 10 ATM water resistance, meaning it’s safe for swimming or shallow snorkeling.
While it’s not suitable for deep diving, most users will find it more than capable of handling everyday water exposure.
The plastic case keeps the watch lightweight and comfortable for all-day use. It’s not as premium-feeling as the metal cases on higher-end Garmins, but it’s tough enough for most outdoor adventures.
Menus, Data, and Ease of Use
One thing I’ve always appreciated about Garmin watches is their menus. The Instinct 3 Solar keeps that tradition alive, offering efficient, easy-to-navigate options.
Is it flashy? Not quite. But it gets the job done, giving you access to vital data like heart rate, elevation, weather, and more.
If you’ve used Garmin’s Enduro or Fenix series before, the interface on the Instinct 3 will feel familiar—it just looks less polished on the MIP screen.
The AMOLED, by contrast, makes even basic menus look more modern and enjoyable.
A Big Miss: No Maps Included
The Instinct 3’s biggest letdown is the lack of onboard maps, even on the AMOLED version. For a watch designed for outdoor adventures, this feels like an oversight.
While basic navigation features like backtracking are still available—letting you save a location and find your way back—it’s no replacement for detailed maps.
If you’re lost in the woods, backtracking is helpful, but maps would’ve made this watch much more versatile.
Garmin Pay: Now Standard
One nice improvement is the addition of NFC to all Instinct 3 models, allowing you to use Garmin Pay.
Previously, this was only available on solar-powered versions. It’s another step toward making this watch a well-rounded choice for daily use.
Garmin Instinct 3 Series Comparison: Solar vs. AMOLED vs. E Models

Final Thoughts: First Impressions of the Garmin Instinct 3 Solar
The Garmin Instinct 3 Solar delivers solid upgrades across the board while maintaining the rugged, feature-packed reputation the series is known for.
Its higher price narrows the gap between it and premium models like the Fenix 8, but the Instinct 3 still offers excellent value for what it is.
If you’re looking for a durable, long-lasting outdoor watch, the MIP model should be your top choice.
On the other hand, the AMOLED version is fantastic for anyone who prioritizes style, brightness, and a more premium feel.
And let’s not forget the Solar models’ flashlight, which turns out to be a game-changer for everyday use.
Overall, the Garmin Instinct 3 Solar feels like a meaningful step forward. I’m excited to spend more time with it and dive into a full review soon.
