The Garmin Instinct 2 Solar is a rugged fitness smartwatch that can track a full day and night of heart rate monitoring off of a few hours of time outdoors, using UV rays so it never dies on the job. It’s a major improvement on the original Instinct in design, battery life, and software. The monochrome display is readable in direct sunlight but a downgrade compared to most other Garmin watches. The shrunken Instinct 2S is shorter-lived but its solar panel counterbalances the battery life woes of most small watches.

Your mileage will vary based on where you live and when you tend to work out. Garmin says the Instinct 2 Solar sports a 30-hour GPS capacity or 48 hours assuming “50,000 lux conditions.” That number equates to an overcast day, so you don’t necessarily need direct sunlight; but if you tend to train during early mornings or evenings or don’t live in a sunny area, you won’t benefit as much from the Solar Panel display. Unless, of course, you have an outdoor day job.
Speaking of the display, it’s a transflective, monochrome memory-in-pixel (MIP) display at 0.9 inches and 176 x 176 pixels. Even cheaper Garmin watches like the Forerunner 55 are slightly more pixel-dense and support multiple colors, so this might belong in the “you won’t love this” category. But it’s a big step up on the Instinct 1, which only hit 128 x 128, and the lower resolution and lack of colors help the battery hit such crazy highs.
In practice, the MIP display is much more visible in direct sunlight than any LCD or AMOLED, and the resolution is high enough that notifications and small metric data are fully readable. Unless you’re really attached to colorful watch faces, the Instinct 2 display works perfectly well for focused athletes

The Garmin Instinct 2 design falls in line with most of its peers: three buttons on the left for the backlight, scroll up, and scroll down buttons, and two right buttons for starting workouts/ selecting options and the Back button. I strongly prefer buttons to touchscreens during races and workouts, and Garmin makes it easy to start or pause an activity or navigate through menus without false touches or futile swiping.
Where it pulls ahead of the pack is durability. Most Garmin watches have 5ATM water resistance and some basic Gorilla Glass protection, but nothing to prevent damage from falls. With the Instinct 2, you receive MIL-STD-810G fall protection and 10ATM resistance; you can basically be sure it’ll never break, even if you tip over your bike or take it deep into the ocean.
Looking back on the original Garmin Instinct, it’s surprising how little data Garmin gave you with it besides basics like Body Battery, sleep/stress tracking, and optional Pulse Ox. The Instinct 2 has those, but also adds HIIT workouts, new sports modes like golf, mountain biking metrics, VO2 Max, training and recovery time suggestions, and training effect/load, among other new metrics. It makes the Instinct 2 much more useful than its predecessor.
It also adds the upgraded Elevate 4.0 sensor, the same one found in the Venu 2 and Fenix 7, giving you more accurate heart rate and SpO2 tracking.
Otherwise, the core Instinct conceit is exploration, so both watches provide a few tools in line with that. The 3-axis compass will point you in the right direction, while the altimeter and barometer measure altitude and weather, respectively. Tracback uses GPS data to see where you’ve gone and the compass to direct you back that direction in case you’re lost. Plus you can pre-download GPX files to find your way to specific waypoints on a hike.
Otherwise, most of the perks with this watch retread old ground for anyone who’s used a Garmin watch before. GPS data and heart rate tracking appeared to be very consistent, matching my running routes and level of intensity.
After completing enough workouts, Garmin Connect provides detailed metrics on your current fitness level without a monthly subscription. Then, once you prepare to start a workout, you’ll receive a suggested pace and time that matches your fitness and will have a good training effect.
GARMIN INSTINCT 2 SOLAR: WHAT YOU WON’T LOVE
Even if the Instinct 2 makes major strides over the original, that doesn’t mean it offers a complete experience, or that everyone should spend such a high price tag just for long battery life.
If you’re a runner, then the Forerunner 245 or 55 may be better if you prefer a watch that holds your hand a bit more. The Instinct 2 offers a decent amount of data, but misses out on Forerunner tools like live pace guidance (aka Pacepro), cadence alerts, estimated finish time, Garmin Coach, and so on. It just doesn’t have the same specialization.
Instead, it’s marketed as “bold, rugged and ready for adventure.” But for actual trailblazing adventures, the monochrome Instinct 2 display doesn’t support onboard maps. So a tool like Tracback involves following an arrow and a black line on a blank inch-sized display — it’s not very intuitive to use! Even if you download a GPX map of your destination in advance, it’s hard to navigate a map with buttons instead of a touchscreen, like you’d get with an expensive Fenix smartwatch.
Lastly, as I mentioned in the intro, the Instinct 2 is fairly basic in terms of connectivity compared to a Venu 2 Plus. You can’t control music playback, answer calls, ask Google Assistant a question, or see live animations of how to complete an exercise. For focused athletes, all of these would just be a distraction; but for people used to lifestyle smartwatches, the Instinct 2 will be far too limited.
All that aside, it isn’t fair to lament that the Instinct 2 isn’t a different watch entirely. Judging it on its own merits, it’s an excellent device for a variety of sports that gives you plenty of data while letting you forget you’re wearing it, similar to a fitness tracker. The only difference is that the Instinct 2 is heavier and more expensive than your average fitness band.
GARMIN INSTINCT 2 SOLAR: COMPETITION
The best competition for the Garmin Instinct 2 Solar comes from other Garmin watches, and depends on what, exactly, you’re looking for in a watch. Among the best Garmin watches, the Fenix 7 has the ruggedness and solar-backed battery of the Instinct 2, combined with the touchscreen of the Venu 2 Plus, improved mapping features, and all the sports modes you could want. Unfortunately, it’s much more expensive than the Instinct 2.
If you need long battery life but don’t like the expensive cost of a Garmin watch, the Coros Pace 2 costs less than half as much and still hits 30 hours of GPS tracking or weeks of idle tracking despite not having a solar panel. It’s also much lighter and gives you free, detailed metrics. But unfortunately, it lacks an SpO2 sensor or NFC payments.
Otherwise, if you’re less concerned about battery life and ruggedness, and more about general features, a Garmin Forerunner 55 will cost much less as well, while giving you a more colorful display and more targeted running features.
