Design

The Garmin fenix 6 comes in more size variants than the Polar Grit X.

If we’re talking about size options, the Garmin fenix 6 is the definite winner. It’s offered in three variants, namely 42mm, 47mm, and 51mm. Not just that but you also have the option to get these sizes in a Pro version if you want to enjoy extra features. Unfortunately, the Polar Grit X is only available in 47mm with either a small, medium, or large band. As for weight, the Grit X is the more lightweight model of the two so that’s something to consider if you need to be as aerodynamic as possible for your sport.

When it comes to screens, the fenix 6 and the Grit X are on the same level, both equipped with an always-on display and backlights. They’re also tied in terms of water-resistance, able to withstand a depth of 100 meters each. They’re a little different in terms of navigation though, with the fenix 6 sticking solely to physical control buttons while the Grit X has both a touchscreen as well as buttons. Its touchscreen isn’t all that great though so you’ll probably depend more on the buttons.

Sports Tracking

The Garmin fenix 6 has more dedicated sports modes than the Polar Grit X.

Both Polar and Garmin are the leaders of the packs when it comes to sports tracking so it’s no surprise that the fenix 6 and the Grit X are robust in features. Whatever kind of outdoor sports and activities you’re into, both models will be able to monitor your progress and provide you with helpful metrics and insights.

According to Polar, you get to enjoy over 130 sports profiles with the Grit X. This includes a bunch of modes dedicated to outdoor lovers including mountain biking, hiking, snowboarding, and running. While that’s pretty impressive, the fenix 6 is just as packed with outdoor sports modes including cross country skiing, kayaking, climbing, and so many more. It might actually have the upper hand because it covers more sports.

As for training, both models do a good job of collecting analytics as you go along. However, the fenix 6 is slightly better at organizing and displaying the information than the Grit X. But at the end of the day, it’s the accuracy of the data that matters the most and their heart rate monitors have a lot to do with that. Both models tend to give mixed results but fortunately, you can hook them up to external chest straps for more accurate readings.

Outdoor and Smartwatch Features

The Garmin fenix 6 has more robust outdoor and smartwatch features than the Polar Grit X.

One of the most important outdoor features to look for in a sports watch is mapping, especially if you’d rather train outside than in a gym. Fortunately, both the Garmin fenix 6 and the Polar Grit X are able to provide proper guidance while you’re up in the mountains or running around your neighborhood. Partnered with Komoot, the Grit X has real-time mapping and route planning. As for the fenix 6, it makes use of Garmin’s own platform to provide real-time breadcrumb trails and point-to-point navigation. The fenix 6 wins in this department because it actually goes a step further by providing additional features such as ski resort maps and topographic maps.

If we’re comparing these models as smartwatches, the fenix 6 wins again. With the Grit X, you’re limited to the handful of basic apps that have been preloaded on it since Polar doesn’t have an app store. This includes sleep monitoring, step tracking, heart rate monitoring, and weather updates. On the other hand, the fenix 6 gives you access to the Connect IQ Store where you can download apps that would serve your day-to-day needs. In addition, you can upgrade the fenix 6 to the Pro version if you’d like to play music straight from your wrist.

Battery

Both the Garmin fenix 6 and the Polar Grit X have dependable battery lives.

If you have a full day of outdoor activities ahead of you, the last thing you need is a dead sports watch. Fortunately, the Garmin fenix 6 and the Polar Grit X have dependable battery lives. With the fenix 6, you can get around 36 hours of usage with its GPS tracking on which extends to 2 weeks if it’s just in smartwatch mode. If you want to get even more juice out of it, put it in battery saver mode for a 48-day battery life.

As for the Grit X, Polar says that it can last up to 40 hours when the GPS is turned on and the heart rate monitoring is being used. You should get around five to seven days though if you’re in smartwatch mode. What’s great is that every sport has its own battery saving plan which optimizes the usage of GPS and conserves energy.

Verdict

The Garmin fenix 6 wins against the Polar Grit X.

If we’re looking strictly at features and capabilities, then the Garmin fenix 6 is hands down the winner of this comparison. It’s offered in more sizes, plus you have the option to upgrade to a Pro version if you want to enjoy advanced features. In addition, it comes with a wider range of sports modes and outdoor features while doubling up as a pretty good smartwatch. However, the fenix 6 burns a huge hole in the pocket, costing around $170 more than the Polar Grit X. So if you’re keen on saving money and don’t mind being limited to more basic features, then it’s better to go with the Grit X.
