Garmin makes a lot of different watches. While brands like Apple, Google and Samsung have two or three smartwatches to choose from, Garmin has dozens, which can make it hard to know which one is right for you.As NBC Select’s fitness and tech reporter, I test out smartwatches, fitness trackers and smart rings regularly: that includes all of Garmin’s latest watches. Below are my top recommendations for anyone looking to make the switch or upgrade an older model.Selected.Our top picksBest overall$undefined$299.99Learn moreBest for runners$449.99$549.99Learn moreBest for battery life$349.99$399.99Learn moreBest premium$undefined$1,095.89Learn moreWant more from NBC Select?

Every option on this list were samples I requested from the brand for testing purposes for this story.Best overallThe Garmin Vivoactive 6 has a subtle and understated look, but still contains many of the brand's best features.Courtesy Harry RabinowitzThe Garmin Vivoactive 6 hits just the right balance of features and price that makes it the easiest option to recommend, especially for someone trying out the brand for the first time.It’s a generalist smartwatch: it has many of the brand’s best features without specializing too heavily in one activity (like the Forerunner series). It has in-depth metrics for health, sleep and fitness activity, with staple Garmin features like body battery, workout recovery times, Garmin pace pro and Garmin coach (with running and strength training plans).I love its workout animations — the watch will play short videos of a silhouette performing certain exercises during HIIT, cardio, strength, yoga or move alert activity. Animated move alerts, in particular, make taking breaks at my desk a lot more fun.The upgrade: Garmin Venu 4The budget alternative: Garmin Forerunner 165Best for runnersI tested the 42-millimeter Garmin Forerunner 570, which fit my wrist much better than the 47-millimeter version.Anyone who loves to run should look at the Garmin Forerunner series — the watches are made with runners in mind. If you’re already deep into your running journey, the Forerunner 570 is my go-to recommendation: It has more than enough tools for runners and racers and comes in two sizes, so you can get the best fit for your wrist (unlike the Forerunner 70 and Forerunner 970).The most important features in my expert opinion are training readiness, training status and HRV (heart rate variability) status, which work in tandem to help optimize your training and recovery. Training Readiness combines multiple metrics to give you a top-level score about how beneficial your training will be. In practice, it helps me decide whether today is a rest day, an easy day or a day to push myself.It has advanced running metrics like power, cadence, stride length and ground contact time, as well as multi-band GPS for the most accurate, consistent distance and time stats possible. It also connects to GPS usually within five seconds.The upgrade: Garmin Forerunner 970The budget alternative: Garmin Forerunner 70Best for battery lifeThe MIP display is easy to read during the day, especially in direct sunlightCourtesy Harry RabinowitzIf you don’t even want to think about charging your Garmin, look for a solar-powered model like this Garmin Instinct 3 solar. It’s a rugged, outdoor-focused fitness watch with many of Garmin’s notable fitness and health features, but with potentially unlimited battery life. That’s because the Instinct 3 has a solar panel built into the screen — get enough sunlight and the watch largely charges itself.Part of this long battery life stems from the screen: it’s a monochrome memory-in-pixel (MIP) display, common on outdoor watches, but not common on many smartwatches. It is easy to see in light conditions, but nearly impossible to see in the dark — press the “Light” button, and the screen will light up for a few seconds.If an MIP screen sounds like a dealbreaker, you can also get the Instinct 3 AMOLED, which has a more typical bright, colorful smartwatch screen and still gets up to 24 days of battery life.The Garmin Enduro 3 and Garmin Fenix 8 (Solar) both get even better battery life than the Instinct 3 (and have solar MIP displays with color), but both cost over twice as much.The upgrade: Garmin Enduro 3The budget alternative: n/aBest premiumThe Garmin Fenix 8 has a durable titanium case and a sapphire crystal screen I didn’t worry about scratching.Courtesy Harry RabinowitzGarmin’s premium, do-it-all watch is the Fenix 8. It has a bevy of features only found in the brand’s high-end watches: things like a dive rating (up to 40 meters), offline maps, navigation and music, a built-in speaker and microphone for calls and music, a built-in flashlight and the list goes on. It’s also likely the most durable — it has a titanium case and sapphire crystal screen, two of the most durable materials you can put in a watch.Outside of premium hardware (and software), I’d recommend the Fenix 8 if you are interested in diving, hiking and trail running: features like dive modes, ascent planning and stellar battery life make it well-suited to these activities.All of that comes at a price: literally. The 47 millimeters AMOLED version that I tested (and linked above) costs $1,099. It’s also surprisingly heavy at 73 grams, heavier than every other watch on this list.The upgrade: Garmin Fenix 8 Pro (AMOLED)The budget alternative: Garmin Epix Pro (Gen 2), Garmin Forerunner 970 Best for styleThe Garmin Venu 4 is one of the brand’s sleekest looking smartwatches.Most of the Garmin watches I’ve mentioned so far look very fitness-forward. The Garmin Venu series is subtle and classy by comparison, and is a great option for anyone who wants Garmin’s best features but in a package that’s easier to match to any occasion. It has a stainless steel bezel that looks great, and comes in two sizes, including a petite 41-millimeter option. It also has built-in microphones, speakers and a flashlight, one I use all the time in dark spaces.The Venu 4 also has many of Garmin’s premium training and health features, including health status, lifestyle logging, Garmin fitness coach, training readiness, training status and HRV (heart rate variability) status. It’s a little pricey, but a great all-around option for most people not needing the five-buttons control, fitness look of the Garmin Forerunner series.The upgrade: n/aThe budget alternative: Garmin Vivoactive 6Best for Apple Watch convertsIf you love everything about your Apple Watch but are considering trying out Garmin, I recommend the Venu X1. It’s Garmin’s most Apple-like watch, with a huge, bright square screen and a very thin case size (eight millimeters). But it has most of the same features as other pricey Garmins, meaning runners, racers, hikers and bikers won’t feel like they are “missing out” getting this model instead of a Forerunner or Fenix.The Venu X1 does have less battery life than most other Garmin watches — up to eight days in gesture mode and only two in always-on mode.The upgrade: n/aThe budget alternative: n/aHow I test Garmin watchesI typically wear two watches at the same time (one on each wrist) and compare data between the two. (I don’t typically wear four, as pictured above.)Courtesy Harry RabinowitzI am a runner and cyclist, and use smartwatches and fitness trackers to track and monitor live stats like heart rate, pace and time as well as recovery metrics over time. I tend to spend hours tinkering with device settings, exploring what a product offers out of the box, and what I can fine-tune to match my preferences.I test Garmin watches for at least a week, using as many features as possible, usually comparing them (and the data) to another watch (on my other wrist) or smart ring. I’ve tested nearly a dozen Garmin watches over the years.I request Garmin watches from the brand — it sends me devices to test out as needed. I send each one back to the brand once I am done testing.How to shop for a Garmin watchEven after you pick out which type of Garmin watch you want, there are still a few key factors you should keep in mind.SizeMany Garmin watches come in multiple size options: the Garmin Fenix 8, for example, comes in 43, 47 and 51 millimeter options. I have smaller wrists (about six inches in circumference), and have tested many smartwatches, so I know that I prefer my smartwatch to be between 42 and 45 millimeters. I err on the larger end if the watch can only be controlled via the touchscreen, and not buttons along the sides.What size is right for you depends on your wrist circumference, but also personal preference. My advice: visit a store like REI or Fleet Feet in person; most have multiple Garmin watches you can try on, in my experience.Key sportIf you love one activity in particular: think running, diving or hiking, you should probably stick to a Garmin watch built around that activity. For divers: it’s the Garmin Descent or Garmin Fenix 8. For runners: it’s any of the Garmin Forerunner watches. For hikers and trail runners, there are a few options across the Forerunner, Instinct and Fenix lineup, depending on your exact needs. If you are more of a fitness generalist, the Garmin Vivoactive and Garmin Venu are the best options.Screen typeMost newer Garmin watches come with a bright, colorful AMOLED display, the kind of screen you see in the Apple Watch, Samsung Galaxy Watch, Google Pixel Watch and most Fitbits. But some Garmin watches, particularly those focused on battery life, solar charging and the outdoors, have a memory-in-pixel (MIP) display. A MIP display is always on but barely uses any energy to power, so it typically allows for a watch with far greater battery life than one with an AMOLED display. MIP displays are easy to read in sunny conditions but become hard or nearly impossible to see at night or in darkness (unless you hit the “light” button to briefly activate the watch backlight).I recommend an AMOLED display for most people — if you want an MIP display, you probably already knew it before reading this article.Why trust NBC Select?I am a reporter at NBC Select who covers technology and fitness including recent stories on fitness trackers, wireless earbuds and cameras.
