Garmin Fenix 8 Pro microLED: One minute review

The Garmin Fenix 8 Pro microLED is both a fantastic always-on, lifestyle-support smartwatch, and a 51mm, titanium-bodied multisport watch bulked out with the kind of rugged design that could survive the entire Die Hard franchise. It’s absolutely one of the best Garmin watches ever made, but also one of the most expensive.

Of course, the headline ‘brightest smartwatch screen ever built’ feature of this microLED edition is justifiably front and centre, but it also provides the 8 Pro microLED with best-in-class performance, screen clarity and brightness.

It’s bursting at the seams with activity, performance and health tracking features backed up by snappily accurate sensors, which enabled real-time monitoring of everything from shifts in barometric pressure outside in the hills to automatically detecting the start of another eight-metre vertical rep in the indoor climbing wall.

Once you dial the brightness up to maximum in the settings (despite all the hype, the default is befuddlingly set to 75%) the step up in brightness from AMOLED is dazzlingly obvious, and contributes to an impression of increased definition too. In fact, the watch screen is so bright that I could easily use the inbuilt mapping mode to navigate in direct overhead summer sunshine while wearing sunglasses, which is a quality of life gamechanger for outdoor adventurers. And putting it side by side against a maxed-out-brightness iPhone in these conditions really hammers home the benefits of the 4,500 NITs of light coming from those microLEDs.

This next-level brightness is maintained even when viewing the watch face from an acute angle, which can be surprisingly useful when glancing at your watch mid-run or taking quick compass bearings, for instance.

Despite the Garmin Fenix 8 Pro microLED’s 51mm, beefed up form factor (it’s 1mm thicker and 3 grams heaver than the already-thick AMOLED version) I quickly grew used to wearing it 24/7 so that I could really dig into Garmin’s lifestyle, training and health monitoring features. It’s chunky, of that there’s no doubt, but I found the combination of a supremely comfortable, flexible strap and well-designed watch body surprisingly easy to wear all-day and overnight. For the first time in a long time, possibly ever, I found that the sleep monitoring data matched my lived experience almost exactly, which gave me faith in the smartwatch to provide useful, actionable data and insights into how to improve the duration and quality of my sleep without feeling ‘nagged’ to do so.

As befitting a true multisport smartwatch, I took the Garmin Fenix 8 Pro microLED everywhere from trail running around London to hiking national parks in sideways rain and from snowboarding at 50mph down a French Alp in -18°C windchill to scaling routes in an indoor climbing wall. I was consistently impressed with the automatic tracking and accuracy of the various activity modes once they’re activated (and there are a lot of modes, including eight running sub-modes and not just Snowboarding but Backcountry Snowboarding too).

I love data but I hate lots of pain points in the tracking experience, so the ability of this smartwatch to intelligently detect and log activity is unsurpassed, in my experience. I found that this smartwatch wasn’t flustered by extreme conditions or environments and the battery life remained consistent even as the iPhone in my pocket was spluttering and dying in sub-zero temps.

Speaking of battery life, it’s nominally less than the AMOLED version, but in practice I got at least four days life on a single charge with Always-On Display on and was pleasantly surprised by its longevity. In situations where battery life was critical, I got used to toggling off the Always-On screen, which made battery life jump to 10 days+. Unlike some smartwatches, there was no perceptible lag when turning your wrist to activate the screen so you don’t sacrifice much usability with this setting.

I also appreciated the rugged design, which shrugged off knocks and scrapes when high in the mountains. Ironically, the biggest impact was when I punched the bezel into a plastic hold when climbing indoors and made the whole wall shake. The sapphire screen remained resolutely unmarked and while I did scrape the very edge of the adonised black finish off the bezel, the titanium itself was undamaged. I look forward to the time when the form factor can be shrunk down, but until then the durability of this smartwatch will see you through despite its egregious, easily-knocked size.

On paper, the brightness upgrade of microLED over AMOLED seems like a ‘nice to have if you have the cash’. But in practice, the real-world experience of discovering unexpected performance and quality of life improvements from a brighter screen are compelling. The upgrade is worth it, and makes me hopeful for the future of microLED technology coming to other smartwatches.

Garmin Fenix 8 Pro microLED: Price and availability

• $1,699.99 / £1,399.99 / AU$3,399.99
• A significant leap above the Garmin Fenix 8 Pro AMOLED
• In a price class of its own for a multisport smartwatch

The Garmin Fenix 8 Pro microLED retails for £1,399.99, $1,699.99, AU$3,399.99

That breaks out from the upper reaches of multisport smartwatches and approaches the terrain of luxury connected watches such as Tag Heuer’s Connected Caliber E5. So, you need to be convinced of the benefits of brightness, because that’s 100% what you’re paying for.

How I tested

I wore the Garmin Fenix 8 Pro microLED over several months, including stints wearing it 24/7 overnight and for very varied activities and workouts including trail running, indoor climbing, snowboarding, weight lifting, sailing and cycling. I was in 35°C heatwaves and -18°C blizzards, from sea level to 4,000m.
