Last month, Garmin launched new high-end options for its adventure smartwatch line: the Fenix 9, the Fenix 9 Pro, and the Fenix 9 Pro Solar. I tested the most premium of the bunch, the Fenix 9 Pro Solar, on a recent trip to Bend, Oregon, which turned out to be a better proving ground than my usual big-city routine.
Garmin markets this watch as the company's "most advanced training, mapping, and connectivity experience yet," and after a week of leaning on it in genuinely unfamiliar territory, I'm inclined to believe that marketing copy. I used the Fenix 9 Pro Solar to navigate a 16-mile trail route I'd never hiked before, leaning entirely on its onboard mapping rather than a phone. My hotel had a pool, so I got to see how it handled swim tracking. And because I had a roommate along for the trip, I ended up comparing the watch's built-in flashlight versus my phone's for the most important test of all: Finding the bathroom in the middle of the night without waking anyone else up.
I opted for the solar version ($1,099.99) specifically for the extended battery life, which I assume is a priority for anyone outdoorsy enough to need a watch costing over $1,000. If the display looks a little muted or less vivid in photos compared to what you've seen elsewhere, that's just the trade-off Garmin makes for solar charging on this model—the standard Fenix 9 ($999.99) and the non-solar Fenix 9 Pro ($1,099.99) use a brighter AMOLED panel instead. (If you'd like to dive into the differences between these three Fenix 9 options, here's a product comparison on Garmin's site.)
Garmin Fenix 9 Pro (Solar) display
The Fenix 9 Pro's AMOLED option is rated for up to 3,000 nits of brightness, triple the 1,000-nit rating on the Fenix 8's AMOLED panel, and the 51mm Pro model gets a new 1.5-inch display, up from 1.4 inches on the Fenix 8 Pro. I tested the solar variant, which uses a different panel technology to enable Power Glass charging, and it's a real trade-off: colors are more muted, and the screen isn't as crisp as the AMOLED version in bright conditions. That's the deal you're making for the extra battery life, and it's worth going in with the right expectations rather than assuming you're getting the same screen as the standard Fenix 9.
Garmin Fenix 9 Pro (Solar) mapping and navigation
This is where the Fenix 9 Pro Solar impressed me most. Garmin was already the class leader on outdoor mapping, and the Fenix 9 Pro pushes that lead further. Turn-by-turn navigation on my 16-mile Bend route was reliable and easy to follow at a glance, and map panning felt noticeably snappy. Garmin credits a 50% RAM bump for up to 30% faster panning, and in practice, scrolling around a map while route-planning didn't have nearly as much of a laggy, catch-up feeling I've experienced on other watches. With 64GB of onboard storage, you can also download roughly twice as many offline maps as the Fenix 8 allowed, which matters if you're the type to load an entire mountain range before a trip.
Garmin Fenix 9 Pro (Solar) battery and charging
Solar charging is the reason to consider this watch over its siblings. Assuming all-day wear with 3 hours per day outside on fairly sunny days, Garmin rates the Fenix 9 Pro Solar at up to 34 days in smartwatch mode. (Stay tuned as I test what it actually takes to charge a Garmin with solar power.) Even a fraction of that battery life claim is a real advantage on multi-day trips. Traditional charging speed held up well in my testing—I was able to get the watch from dead to full battery within an hour, which is handy if you only have a short window to top off before heading out.
Garmin Fenix 9 Pro (Solar) design and build
The Fenix 9 Pro is the first Fenix smartwatch to get a full titanium case. It feels dense and durable in a way that's reassuring on the trail but noticeably heavier day-to-day than something like a Forerunner. Garmin claims the case is actually 16% thinner than the previous Fenix generation, and longtime Fenix owners may notice that more than I did coming from a lighter watch. Personally, I've decided I'm not a fan of sleeping in it—it's just bulky enough that I'd rather take it off overnight. The new ComfortFit accessory bands, which use a stretchy fabric design, are a nice touch if you want something less rigid than the standard silicone strap for everyday wear.
The integrated LED flashlight, which adds a green light mode on the Pro to help preserve night vision, is not a replacement for a proper headlamp on a night run or hike. But for the mundane, universal problem of needing light in the dark without blasting your phone's screen brightness at your own face (or your roommate's), it's excellent. I'm truly shocked how often I use it.
And while the Garmin fēnix 9 Pro is dive-certified up to 40 meters (131.2 feet), I was only able to test it in about 5 feet. Still, tracking a swim was intuitive and accurate, with the watch sensing every time I started a new lap.
Garmin Fenix 9 Pro (Solar) sensors and everyday accuracy
No surprise, but I didn't run into anything alarming here—heart rate, GPS, and the other core sensors all performed the way I've come to expect from a high-end Garmin watch.
Garmin Fenix 9 Pro (Solar) training features: Garmin Epic and Stamina
Garmin's new software layer adds two headline features. Garmin Epic—not to be confused with the older Epix product line—lets you group multiple activities and training blocks into a single, shareable story in Garmin Connect. It plots all your activities on a color-coded map by activity type, with a rundown of health and activity stats underneath. It's a nice way to look back at a multi-day trip or training block as a whole rather than as disconnected activities.
The new stamina tracking, including stamina zones and a stamina curve, is the more useful addition for regular training. The stamina curve estimates how long you can sustain different effort levels—pace for running, power for cycling—based on your accumulated training data, and it updates as your fitness changes. Easy efforts drain the curve slowly, near-maximal efforts drain it quickly, and watching it shift over a training block gives a genuinely useful sense of how your endurance is trending.
That said, neither Epic nor the stamina features feel like they're worth a hardware upgrade on their own. This leads me to my next major point: This watch is not a casual upgrade, full-stop.
Garmin Fenix 9 Pro (Solar) pricing
If you ask me, such a premium price tag tells a story about who this watch is for. The Fenix 9 Pro starts at $1,099.99, and the solar model I tested here has the same starting price, climbing to $1,399.99 for the largest 51mm case with inReach. That's before factoring in an inReach subscription if you want to actually use the satellite features.
For context, Garmin's own move to launch the Fenix 9 line has already pushed Fenix 8 pricing down from $1,099.99 to $849.99, which makes last year's model a perfectly reasonable option if you don't specifically need the titanium case or the latest mapping engine. And if you're comparing across the current lineup, the standard Fenix 9 starts at $999.99 with a lighter fiber-reinforced polymer case instead of titanium, and drops the solar charging option entirely—also a reasonable trade if budget matters more to you than build material or maximum battery life
The Garmin Fenix 9 Pro Solar completely meets expectations for a Fenix flagship: excellent mapping, a durable and premium build, strong battery life, and a handful of small quality-of-life features (like that flashlight) that make it easy to like in daily use. It's worth paying attention to, because Garmin continues to lead the outdoor GPS watch category, and this generation pushes that lead further with a brighter display option, meaningfully faster map performance, and satellite connectivity now available across every case size rather than just the largest one.
So who should actually buy this watch? Not current Fenix 8 owners, in most cases—the upgrades probably aren't enough to justify such a dramatic jump in price. This watch makes the most sense for anyone whose Fenix 7 or older watch is on its last legs. After all, the Fenix 9 Pro is a damn fine watch, especially for anyone who spends serious time navigating unfamiliar trails—and can justify the spend.
Garmin Fenix 9 Pro Solar Review FAQ
What sizes does the Fenix 9 Pro come in?
It's available in 43mm, 47mm, and 51mm cases, with the 43mm size available at the Pro and inReach tiers for the first time in the Fenix line.
Do Garmin solar versions look worse than the standard AMOLED model?
Not worse, exactly, but definitely different. The solar display trades some brightness and color vibrancy for significantly longer battery life through Power Glass solar charging.
Do I need an inReach subscription to use Garmin watch's satellite features?
Yes. The hardware is built in, but two-way satellite messaging and SOS functionality require an active inReach plan, which is a separate ongoing cost.
