The Garmin Fenix 8 is a good activity watch by every conceivable metric, and rated our best Garmin watch in the premium category. I gave the Fenix 8 five stars when I reviewed it in September 2024, and I've been wearing it on and off ever since, while testing other wearables in between. It's accurate in terms of GPS and heart rate, it's fast, it's eminently customizable, and stuffed with neat, handy features. It's got everything from some of the best navigation software I've ever used to advanced training plans courtesy of Garmin Connect. It's tough, built with titanium and either hardened Corning Gorilla or Sapphire glass, and has a battery life lasting around two weeks, depending on the model and size. It's been my daily driver, and frankly, even as a wearables and fitness tester, it's probably too much watch for me. I don't use all the features regularly, but I love big shiny Garmins. So, two years on, would I get it in 2026? The answer is definitely yes, provided you're someone who will get the most out of it. If you love (and I mean, really love) a whole variety of outdoor pursuits, be they hiking, running, cycling, swimming, orienteering, or a combination of the above, plus other indoor fitness activities like gym sessions, you'll love this watch and consider it good value for money. If you dabble in activity rather than living and breathing it, you might be better off saving yourself some money and buying a lower-power, lower-feature device like a Garmin Forerunner or Garmin Instinct 3. But for dedicated outdoor enthusiasts, I struggle to imagine a better watch. If you're in the market for a new Garmin, some of the Prime Day deals (like the ones below on the 43mm Garmin Fenix 8) might look pretty appealing. However, unless you spot a particularly historic deal (say, under $700 / £600), I'd actually recommend waiting. Here's why.US deal: $250 off the five-star Garmin Fenix 8 in its smallest 43mm size and Whitestone colorway. Perfect for those who want serious power on smaller wrists (and adventure watches are usually big, lumpy affairs), it still packs an impressive 10-day battery life, advanced training features, an LED flashlight, and full-color maps. View DealUK deal: £145 off the same model as the US deal above. A five-button configuration and AMOLED touchscreen mean you can operate the watch while wearing gloves in adverse weather conditions. It's perfect for hikers, skiers, campers, and triathletes.

Garmin's outdoor line of watches had a high-profile refresh with the Garmin Instinct 3 release last year, so a big outdoor watch launch for 2026 is likely to mean only one thing — the Garmin Fenix 9.The timings make sense. Two years after the Fenix 8 launches is ample time for users to get excited about a Fenix 9, just as the 8 came two years after the Fenix 7. I must admit, I personally don't think there's going to be too much change under the hood: a Fenix 9 will cost more due to the recent supply chain price increases, and is unlikely to boast an enormous performance upgrade. However, what the new watch will do — if it launches this year — is to drive down the price of the old one, just as the Fenix 8 has done with the Garmin Fenix 7 and Garmin Epix Pro (Gen 2). These incredible watches can now be found at better-than-half their original prices, and at that sort of price cut, I'd certainly recommend the Garmin Fenix 8 over the likes of a fully-priced Garmin Forerunner 570. So, if you're holding out for a Fenix 8, it might be prudent to skip the Prime Day deals this year and wait till a sales event in the back half of the year, such as Black Friday, in case the Fenix 9 comes along to knock the 8 off its perch. However, don't be dissuaded from browsing the rest of the Amazon Prime Day deals, just in case you do find something you're looking for.
