Garmin no longer needs to demonstrate its mastery in the world of high-end multisport watches. With the Fenix 7 Pro Solar , the American brand is clearly aiming for technical perfection while consolidating its status as the absolute benchmark in the field of sports monitoring. From the first hours on the wrist, you feel that you are holding much more than a simple training tool: it is a true adventure companion, designed to withstand everything and accompany every effort, from urban interval training to Alpine summits.
On paper, the promise is dizzying: record battery life thanks to solar charging, surgical GPS precision, next-generation sensors, and military-grade robustness. But as always with Garmin, theory isn't enough. The Fenix 7 Pro Solar had to be tested over time, confronted with reality, the cold, the rain, and sweat. And after several weeks of intensive testing, between daily sessions and more extreme explorations, one thing became clear: this watch isn't just an update, it's a true demonstration of expertise.
A major evolution of the classic Fenix 7, this Pro version is distinguished by a trio of significant innovations: the Elevate 5 for more reliable measurements, solar charging now extended to the entire range, and an integrated LED flashlight , as practical for night running as during an impromptu bivouac. Additions that, on the field, truly transform the experience and pose a simple question: has Garmin finally created the perfect multisport watch?

A design made for adventure, but not only
From the moment you lift the lid of the box, the Garmin Fenix 7 Pro Solar naturally commands respect. Its looks don't lie: it's a watch made for action, forged for hostile terrain, but elegant enough to invite itself under a shirt. Garmin has thought of all wrists with three case sizes: 42, 47 and 51 mm and our test model, the 47 mm Gray version with Black Strap , perfectly illustrates what the manufacturer does best: a near-perfect balance between robustness, finesse and comfort.
The connected watch immediately stands out for its lightness. At only 73 grams , the Fenix 7 Pro is almost forgotten on the wrist, even after a full day of effort. Yet, its case exudes solidity. Every button, every edge, every screw gives off an impression of industrial precision. You can feel the design work behind this watch, designed to withstand everything without sacrificing aesthetics. The impeccable finishes , the consistency of the materials and the sober colors : gray, black or white make it a watch that can be worn as much in the mountains as in the city.
But the real star here is the MIP (Memory-In-Pixel) display . Garmin isn't giving in to the flashy AMOLED trend, and it's a conscious choice. Readability remains excellent in direct sunlight , where other screens almost fade. The 260 x 260 pixels on our review unit offer remarkably clear viewing, whether on an exposed trail or under overcast skies. MIP technology excels where it should: displaying essential data without compromising battery life.
And like any self-respecting adventure watch, the Fenix 7 Pro is unafraid of the elements. Its 10 ATM certification (up to 100 meters) allows you to dive, run in the rain, or swim without a second thought. As for the sapphire crystal , it effectively protects the screen from scratches and shocks, an essential asset when venturing into terrain where every stone can become an adversary.
Solar charging: revolution or gimmick?
With the Fenix 7 Pro Solar, Garmin is taking its ambition of energy independence even further. The brand no longer just promises autonomy; it actually delivers it. All models in this generation now benefit from solar charging via Power Glass, capable of transforming each ray of light into additional energy. A technological feat that, on paper, is a dream: up to 37 days of battery life in connected use and 139 hours of continuous GPS use. Almost unreal figures, worthy of a device with infinite energy.
But the real question remained: how do these promises hold up in the field? After several weeks of testing, the answer is obvious. In daily use, with active notifications, sleep tracking, and a few workouts per week with GPS, the Fenix 7 Pro Solar lasted more than three weeks without recharging. Three full weeks of real-world battery life, without worrying about a cable or a plug. This watch literally changes our relationship with technology. We don't recharge it anymore, we live it.
And then comes this almost magical moment. During a long hike under a big blue sky, the watch gained a few percent of battery despite having a permanently active GPS. This simple detail speaks volumes. For adventurers, hikers, or long-distance runners, this technology is not a gimmick. It's a silent revolution, a total energy liberation. The Fenix 7 Pro Solar no longer depends on the mains; it powers itself at the rhythm of the sun.
An impressive technological arsenal
On the wrist, the Fenix 7 Pro Solar immediately imposes its presence. You immediately feel that this isn't just a simple watch, but a true concentration of technology, designed to accompany every movement, every heartbeat, every step on demanding terrain. The new Elevate 5 sensor surprised us from the first kilometers. While many watches stumble when faced with intense sessions, this one keeps pace without flinching. During our runs, we compared its readings to a reference chest strap and noted minimal differences. For a wrist-mounted sensor, this is a feat that inspires confidence.
We then pushed the test into more extreme conditions. In the heart of a dense forest, with GPS activated, you might expect to lose the signal at every turn. The Fenix 7 Pro Solar, imperturbable, traces our route with astonishing precision thanks to its multi-band GNSS technology . Every turn, every hairpin, every summit is recorded without a hitch, which transforms a simple outing into a truly controlled exploration.
The SatIQ also impressed us. On long straights, the watch automatically reduces the recording rate to save battery, while on technical single-track sections, it increases the cadence to capture every detail of the track. During our rides, this adaptive intelligence proved essential: battery life remains impressive without sacrificing accuracy, a rare balance in this type of watch.
On the navigation side, the Fenix 7 Pro's 32GB of internal memory quickly fills up with topographic maps and routes. Combined with the barometric altimeter and electronic compass, they make the watch an indispensable adventure companion. And then there's that little extra that really makes it stand out: the integrated LED flashlight . On a night out, a double press of the button and darkness is no longer a problem. Powerful enough to consult a map or find an object, with strobe modes capable of signaling distress. These details, often overlooked, transform an already exceptional watch into an unexpected survival tool.
A user experience designed for the field
Spending a few days with the Fenix 7 Pro Solar is like taming a war machine. At first glance, its interface can be confusing. Garmin has never been a champion of simplicity, and the richness of its menus can be intimidating. But after a few days of use, everything becomes clear. You understand the logic, you discover the coherence of the system, and above all, you realize that this watch was designed by athletes for athletes.
The five physical buttons fall perfectly under the fingers. Even with wet gloves or in freezing weather, they respond instantly. The touchscreen , meanwhile, provides support for navigating maps or quickly consulting data. This duo of buttons and touchscreen creates a hybrid, intelligent ergonomics that adapts to the situation. When racing, the button remains king; when stationary, the touchscreen takes over. A subtle but formidably effective balance.
And then there's the depth of content. The Fenix 7 Pro doesn't just track your steps—it literally knows every sport . Running, trail running, mountain biking, skiing, swimming, climbing, yoga, golf, triathlon—the list seems endless. Each profile is calibrated with precise metrics, customizable screens, and analytics that dive deep into performance. During our running sessions, the data was displayed with fascinating precision: pace, cadence, stride length, vertical oscillation, ground contact time, left-right balance. So many indicators that transform a simple session into a complete study of movement.
But Garmin doesn't just measure, it interprets training suggestion system learns from you, day after day. It analyzes your performance, your recovery, your fatigue, and suggests sessions calibrated to your current form. And the new features of this Pro version, the endurance and ascent , go even further. These two indicators concretely translate your capacity to maintain a prolonged effort or to absorb successive climbs. During our long outings, their estimates proved surprisingly accurate. We end up trusting the watch like an invisible coach, capable of anticipating your limits even before you feel them coming.
The Garmin Connect app: a complete control center
Connecting the Fenix 7 Pro Solar to the Garmin Connect is seamless. Bluetooth automatically takes over, and within seconds, all your activities are displayed on your smartphone's screen. The interface may seem dense at first, but it quickly reveals its richness: detailed GPS tracks, altitude curves, minute-by-minute heart rate, training load, trends over several weeks... everything is there for those who like to analyze every detail of their performance.
The watch doesn't just count steps, it constantly monitors your body. Heart rate, sleep quality with distinction between light, deep and REM phases, oxygen saturation , stress level, guided breathing: the Fenix 7 Pro Solar knows everything about you and helps you better manage your daily life. During our weeks of testing, each metric seemed to faithfully reflect our real-life sensations, giving an almost scientific overview of our fitness and recovery.
Body Battery system perfectly illustrates this approach. By aggregating all the data collected, it provides an estimate of your energy on a scale of 0 to 100. After several days of intensive use, we were surprised by the relevance of this score. It warns of periods of fatigue before you even feel them and becomes a true strategic tool for planning training and rest. With Garmin Connect, the Fenix 7 Pro Solar is no longer limited to the wrist: it becomes a true control center for your body and your performance.
Mapping and navigation: a benchmark outdoor GPS
It's probably in the area of navigation that the Fenix 7 Pro Solar reveals its full power. From the very first steps on the trails, the preloaded topographic maps transform the watch into a true hiking GPS. The accuracy of the route is impressive, the wealth of information with contour lines, points of interest, and marked trails is remarkable, and navigation remains incredibly fluid. You immediately feel that you're holding a tool designed for demanding adventurers.
During our explorations in unfamiliar terrain, the traceback proved reassuring. With just one tap, the watch retraces our steps by following the reverse GPS track. Even without a planned route, setting out on an adventure becomes a serene pleasure, with the certainty of finding your way back.
Compatibility with Komoot and Strava opens up endless possibilities. Importing and following routes becomes simple and intuitive, and vibrating alerts when you go off-route allow you to stay on track without having to constantly check the screen. Each outing becomes a controlled exploration, where technology remains discreet but essential to secure the experience.
Music and payment: connected life made simple
The Fenix 7 Pro Solar doesn't just track your athletic achievements; it also simplifies everyday life. Its generous memory allows you to store hundreds of tracks directly on the watch. Paired with Bluetooth headphones, it transforms every outing into a full-fledged music session without the need for a smartphone. Compatible with Spotify, Deezer, Amazon Music , and other streaming services, it can automatically download your playlists via Wi-Fi, offering total autonomy and unparalleled convenience.
Garmin Pay integrates with the same seamlessness. With a double tap of a button and a PIN, you can pay for your purchases directly from your wrist. Whether you're buying a drink on a long outing or making a quick payment in town, the watch makes these everyday tasks simpler and faster, eliminating the need to carry your phone or wallet.
Smart notifications complete this connected experience. They effectively filter smartphone alerts to retain only the essentials. You stay informed without being overwhelmed, with the ability to quickly respond with predefined messages on Android or simply reject a call. The watch thus becomes a true extension of your digital life, always within reach of your wrist, without ever becoming intrusive.
Against the competition: where does the Fenix 7 Pro stand?
Compared to the standard Fenix 7 , the Pro version marks a real qualitative leap forward. The Elevate 5 sensor brings increased accuracy, solar charging is no longer reserved for Sapphire models, the integrated flashlight facilitates nighttime outings, and the endurance and climbing scores offer a detailed reading of fitness and capacity to withstand efforts. For a few dozen extra euros, these improvements are fully justified for anyone who uses their watch intensively.
The comparison with the Fenix 8 is more nuanced. The latest generation offers an AMOLED screen for those who prioritize display quality over battery life, further optimized solar charging, and new features like watch-based calls and voice commands. These new features are appealing on paper, but they remain superfluous for the majority of athletes who are primarily looking for precision, robustness, and battery life.
The Fenix 7 Pro is therefore a thoughtful and rational choice. It brings together the essential advanced features, at a price that is now more accessible, especially during regular promotions. For purists of autonomy and outdoor readability, its MIP screen even retains an advantage over the AMOLED of its little sister, offering perfect visibility in full sunlight, without compromising on battery life.
