Garmin Fenix 8 Pro review: The best Garmin watch, but not the best buy

I’m way overdue with this Garmin Fenix 8 Pro review. I tested the MicroLED version of Garmin’s flagship wearable when it came out and have worn the AMOLED version a lot since then, but somehow I never found the time to put my thoughts into words. Turns out, you can’t forever put off doing things!

Not like writing what’s admittedly the best Garmin watch (well, the most feature-rich, anyway) is a huge burden. I’ve always loved using Garmin products, and the Fenix line has always held a special place in my heart, thanks to its rugged build and excellent mapping functionality.

That said, it almost feels like the Fenix 8 Pro came a bit too soon after the Garmin Fenix 8. Don’t get me wrong, it was an important launch – the world’s first microLED smartwatch! – but from a features perspective, it offers little that is tangibly different from its predecessor.

Sure, inReach Messenger is nice, and so is the MicroLED panel, but otherwise, you’re getting the same sensors and, most importantly, almost the carbon copy of the Fenix 8 user experience, especially if you opt for the AMOLED model.

I certainly wouldn’t throw away my Fenix 8 to get a Fenix 8 Pro, but even with that, it’s hard to deny that the Fenix 8 Pro is the best outdoor watch right now, all things considered. If you have an older Fenix and are keen on staying in the Garmin ecosystem, you’ll love the Fenix 8 Pro. Should you get one? Let’s find out.

Garmin Fenix 8 Pro review

Price and availability

The Fenix 8 Pro was launched in September 2025 and is available to buy now at Garmin UK, Garmin US, Garmin AU and Garmin EU.

The AMOLED version is available in 47mm and 51mm sizes, and starts at £1,030 / $1,200 / AU$2,100 / €1,300. The MicroLED option comes in one case size only (51mm) and costs a whopping £1,500 / $1,700 / AU$3,400 / €1,800.

The MicroLED retailed for more at launch, but Garmin has since permanently dropped the price to entice more people to get the watch. It’s still a huge investment, but there are often deals on the AMOLED version. Recently, Amazon knocked the price down to £726 in the UK.

Design

The Garmin Fenix 8 Pro is available in 47mm and 51mm case sizes, pairing them with a fibre-reinforced polymer case with a titanium rear cover, while the sapphire edition adds a lightweight titanium bezel and scratch-resistant sapphire crystal lens.

You can opt for Garmin's familiar AMOLED screen or the brand's first-ever MicroLED display. Both offer the same resolution and user interface, but the MicroLED panel delivers significantly higher brightness – up to 4,500 nits – making it exceptionally easy to read in harsh sunlight.

In direct sunlight, the MicroLED looks almost as if the graphics have been printed onto the glass, with outstanding visibility from virtually any angle.

The AMOLED model, meanwhile, peaks at around 2,000 nits, which is commendable but not necessarily on par with some rivals, including the Apple Watch Ultra 3 and the much more affordable Amazfit T-Rex Ultra 2. That said, the Fenix 8 Pro is still among the brightest displays you'll find on a sports watch.

The Fenix 8 Pro is rated to 10 ATM, making it suitable for swimming, freediving and recreational scuba diving, while redesigned leak-proof buttons improve reliability during underwater activities. Unlike other brands (e.g., Huawei Watch Ultimate 2), Garmin doesn’t advertise the Fenix line as a dive-first smartwatch, likely because it has its own dive watch line (the Descent line).

An integrated LED flashlight, complete with white and red light modes, returns for everything from pre-dawn runs to campsite chores. The watch itself can also shift to red mode (the screen), which is handy for after-hours watch staring. You can also set the watch to automatically switch to red shift mode after sunset.

Like the standard Fenix 8, the Pro includes a built-in microphone and speaker for Bluetooth phone calls, voice assistant support and offline voice commands, while Garmin's QuickFit strap system makes it easy to swap bands without tools. It all adds up to one of the most capable and best-built adventure watches currently available.

Features

If you've used a recent Fenix 8 or Enduro 3, very little about the Fenix 8 Pro will surprise you. That's not a criticism; Garmin has spent years building arguably the most comprehensive fitness and outdoor ecosystem on the market, and this generation is more about refinement than reinvention.

The only genuinely headline-grabbing addition is support for Garmin inReach messaging over LTE, allowing users to send and receive messages via the satellite communicator without carrying a phone, provided they have a compatible inReach subscription.

Prices start at £7.99 / $7.99 / AU$11.99 / €9.99, which is way more than the Oura subscription, for example, and it ‘only’ lets you message people when there is no reception. As such, this feature is only really useful for people who spend a lot of time off grid and require the ability to communicate with others who aren’t (unless the whole team have Fenix 8 Pro watches).

Health tracking is handled by Garmin's latest Elevate Gen 5 optical heart rate sensor, which debuted in May 2023 on the Garmin Fenix 7 Pro and the now discontinued (and very cheap) Garmin Epix Pro (Gen 2). It supports 24/7 heart rate monitoring alongside Pulse Ox, skin temperature tracking, ECG, respiration, stress tracking, Body Battery, HRV Status and advanced sleep analysis with Sleep Coach and nap detection.

Training features are equally extensive, with Training Readiness, Training Status, Daily Suggested Workouts, Endurance Score, Hill Score, Race Predictor and Garmin Coach all returning. The Fenix is the brand’s top outdoor watch, and as such, the UI prioritises mapping and navigation, but you can find all other training, health and smart features in the menus.

Strength training has also continued to improve, with automatic rep counting, muscle maps and guided workouts making it genuinely useful in the gym, while support for dozens of activity profiles means everything from trail running and ski touring to paddleboarding and open-water swimming is catered for.

The built-in microphone and speaker enable Bluetooth phone calls when paired with a smartphone, while voice assistant support lets you interact with Siri or Google Assistant if that’s what your heart desires.

I’ve never been too keen on chatting with my watch (or phone or smart speaker, the latter of which I don’t have), but given the price and the flagship nature of the Fenix 8 Pro, this is a feature Garmin must include.

The company also includes offline voice commands, allowing you to start activities, set timers or control certain watch functions even when you're away from mobile reception. Music storage, contactless payments via Garmin Pay, smartphone notifications and access to the Connect IQ store round out the experience.

Mapping, navigation and accuracy

Navigation has long been one of the Fenix series' biggest strengths, and the Fenix 8 Pro continues to set the benchmark. It comes preloaded with TopoActive maps, detailed road and trail mapping, ski resort maps and golf course data, while downloadable regional maps ensure you can plan routes and navigate without needing a phone signal.

There aren’t many watches I would trust for offline maps and route planning in uncharted areas, but Garmin watches have never let me down. Maps can be downloaded via the Connect app, and the map options are clearly labelled (e.g., United Kingdom and Northern Ireland). It’s a system that works and has been working for a long time.

Features such as ClimbPro break down upcoming ascents, NextFork shows the distance to the next trail junction, and Up Ahead lets you see upcoming aid stations, summits or points of interest. None of these is new, but they are part of the ever-so-extensive Garmin training ecosystem.

Dynamic round-trip routing remains one of my favourite features, generating surprisingly sensible running and cycling routes directly on the watch, while turn-by-turn navigation makes it easy to stay on course without constantly referring to your wrist.

The Fenix 8 Pro supports multi-band GNSS across GPS, GLONASS, Galileo, QZSS and BeiDou. It features SatIQ (now called Auto Select), which automatically switches to the most sensible GNSS method to conserve battery life. For example, it might switch to single-band in open areas and to maximum-accuracy mode in the forest. The brand doesn’t disclose how this feature works, despite my efforts to find out over the years.

Across months of testing, I found GPS tracks to be consistently clean, with little evidence of corner-cutting or wandering, even on heavily tree-lined trails and urban routes between tall buildings.

As for the Elevate Gen 5, Garmin’s wrist-based heart rate monitoring has improved significantly over the past few years, and during steady-state runs, long hikes and strength workouts, the Fenix 8 Pro tracked closely with a chest strap.

As with almost every optical sensor, short, high-intensity intervals can still produce the occasional lag, but for the vast majority of users, the onboard sensor is accurate enough that a chest strap becomes optional rather than essential.

Battery life and charging

Battery life has always been one of the Fenix range's defining strengths, and while the Fenix 8 Pro continues that tradition, there's now a much clearer distinction between the AMOLED and MicroLED models. If endurance is your top priority, the AMOLED version remains the one to buy.

Garmin rates the 47mm AMOLED model for up to 15 days in smartwatch mode (or eight days with the always-on display enabled), while the larger 51mm AMOLED stretches that to 27 days (or 15 days always-on).

Even in the most demanding multi-band GNSS mode, you're looking at up to 30 hours on the 47mm and 53 hours on the 51mm, giving you more than enough endurance for everything from marathon training to multi-day hiking trips.

Despite using what many expected to be a more efficient display technology, the first-generation MicroLED panel is considerably more power-hungry than Garmin's AMOLED screen.

Officially, the 51mm MicroLED model lasts up to 10 days in smartwatch mode (or just four days with the display always on), dropping to 34 hours in multi-band GNSS mode. That's still respectable by smartwatch standards, but it's a noticeable step backwards for a Fenix, especially one carrying such a significant price premium.

In practice, I found Garmin's estimates to be realistic. As with every Fenix before it, battery life varies widely depending on how you use the watch. Daily GPS workouts, frequent GNSS / map use, pulse oximetry (which I always turn off first thing), music playback (very bad for battery life) and LTE LiveTrack all have a measurable impact.

On the other hand, you have SatIQ, which does an excellent job of balancing accuracy and efficiency by engaging multi-band GPS only when conditions require it. Unless you're intentionally trying to drain it, the AMOLED model is still a watch you'll measure in weeks rather than days, which remains a rarity among flagship smartwatches.

Charging is unchanged (pun intended). The Fenix 8 Pro uses Garmin's familiar proprietary four-pin charging cable rather than adopting USB-C or wireless charging. While I'd still like to see Garmin modernise its charging solution, the cable is secure and reliable, and thanks to the watch's excellent endurance you'll rarely need to reach for it.

Verdict

The Garmin Fenix 8 Pro is, without question, the best outdoor smartwatch money can buy.

It combines class-leading navigation, outstanding training tools, reliable health tracking and exceptional build quality into a package that's as comfortable pacing a marathon as it is guiding you across a mountain range. The new MicroLED display is genuinely impressive, too, delivering brightness that no other sports watch can currently match.

The problem is that most of those strengths were already present on the Fenix 8. Unless you specifically want the dazzling MicroLED display or the ability to use inReach Messenger directly from your wrist, the day-to-day experience is remarkably similar. In short, the AMOLED Fenix 8 Pro is a refined version of an already excellent watch.

That's made more complicated by timing. With the Fenix 9 likely on the horizon, potentially bringing a new optical heart rate sensor and perhaps even combining AMOLED with Power Glass charging, the Fenix 8 Pro doesn't feel like the obvious long-term investment it might have six months ago.

Fortunately, it's now available well below its original launch price, making it considerably easier to recommend than it was at launch.

Even so, I'd still point most people towards the cheaper Fenix 8, which delivers almost the same experience for less money. But if you simply want Garmin's most capable adventure watch and don't mind paying for the privilege, the Fenix 8 Pro wears the crown. At least until its successor arrives.
