Polar has officially launched the Grit X2 smartwatch in the United States, following its successful debut in Europe a few months earlier. Designed for athletes, explorers, and fitness enthusiasts, the Polar Grit X2 offers a robust combination of durability, advanced health monitoring, and navigation features. Positioned as a more affordable alternative to the Grit X2 Pro, this smartwatch retains nearly all the flagship features while maintaining a lower price point. It’s a smartwatch built for endurance, precision, and intelligent training insights—perfect for those who take fitness seriously.
The Polar Grit X2 stands out with a rich set of features tailored for adventure and performance.
The Grit X2 features a 1.28-inch AMOLED touchscreen with a crisp 416×416 resolution, protected by sapphire glass for superior scratch resistance. Its always-on display and automatic brightness adjustment ensure visibility under all lighting conditions, whether you’re training indoors or exploring rugged terrains.
Built for adventurers, the smartwatch includes dual-frequency GPS compatibility and supports GPS, GLONASS, Galileo, BeiDou, and QZSS satellite systems for precise tracking. With turn-by-turn navigation powered by Komoot and offline maps stored on 32GB of internal memory, users can explore confidently without needing a constant phone connection.
At its core, the Grit X2 uses Polar’s Elixir sensor platform, offering a wide range of advanced health metrics. These include ECG readings, SpO2 (blood oxygen monitoring), skin temperature tracking, and Gen 4 optical heart rate sensing. The watch also integrates barometer, compass, accelerometer, and gyroscope sensors to ensure precise environmental and movement tracking during workouts and outdoor activities.
Powered by a 310mAh battery, the Grit X2 delivers impressive endurance—up to 30 hours in performance training mode, 90 hours in eco mode, and around 7 days with typical use. Its 275MHz processor and 37MB of memory handle Polar’s robust fitness suite efficiently. The watch connects via Bluetooth 5.1 and charges with a proprietary USB-C cable.
Beyond fitness tracking, the Grit X2 supports smartphone notifications, music control, and an array of Polar’s proprietary training and recovery tools. These include:
When it comes to rest, the watch offers Nightly Recharge, Sleep Plus Stages, and SleepWise features for comprehensive sleep analysis and recovery insights.
The Polar Grit X2 is available in a 44.7 mm Night Black variant, priced at $799.99 in the United States. While it sits in the premium category, its rich feature set and multi-sport capabilities make it a competitive choice against top-tier fitness watches from Garmin and Suunto.

The Polar Grit X2 combines rugged outdoor design with the sophistication of a modern smartwatch. The display is bright and vivid, making it easy to read even in direct sunlight. The inclusion of sapphire glass adds a touch of durability often reserved for higher-end models.
Performance-wise, the Grit X2 impresses with its accurate GPS tracking and reliable heart rate monitoring. The dual-frequency positioning system ensures precision even in dense forest or mountainous areas—an essential feature for hikers and trail runners.
The Elixir sensor platform is another highlight, delivering medical-grade ECG accuracy and detailed health insights. Meanwhile, the long battery life ensures users won’t be left stranded mid-adventure. On the software front, Polar’s training and recovery ecosystem provides actionable data, making it easier to optimize performance and recovery cycles.
However, while it’s an excellent performer, the lack of onboard music storage and the reliance on Polar’s proprietary ecosystem might be limiting for users expecting full smartwatch capabilities. Still, its core focus on fitness and durability makes it a highly dependable training partner.
If you’re an athlete, trail runner, or outdoor enthusiast looking for a rugged, accurate, and feature-rich smartwatch, the Polar Grit X2 is an excellent choice. It delivers premium health tracking and navigation features while maintaining long battery life and a durable design. For users seeking a fitness-first smartwatch rather than a general-purpose one, the Grit X2 hits the sweet spot.
However, if your focus is on smartwatch functionality—like app support or music streaming—alternatives such as Garmin Fenix 7 or Apple Watch Ultra might be worth considering.
The Polar Grit X2 strikes an impressive balance between performance and price, offering nearly all the capabilities of the Grit X2 Pro in a slightly more affordable package. It’s rugged yet refined, advanced yet practical—a true companion for those who live for endurance and exploration. For serious fitness enthusiasts, the Polar Grit X2 stands out as one of the most capable training watches of 2025.
