The Polar Grit X2 has officially launched in the U.S., and it’s a welcome addition for runners, hikers, and outdoor explorers who’ve been wanting a more compact, less bulky alternative to flagship watches like the Grit X2 Pro.
With its slimmed-down profile, improved wearability, and a still-impressive suite of navigation and recovery tools, this is the most approachable Grit model yet, without sacrificing the core features that matter most on the trail.
Built for adventure, made to wear every day



Despite its relatively compact size, the Grit X2 still feels built for the long haul.
The stainless steel bezel is etched with compass markings, the buttons are glove-friendly, and the 1.28″ AMOLED display is protected by sapphire crystal glass.
It’s passed MIL-STD-810H testing, so you can expect it to hold up in rough weather, freezing temps, altitude, and even total immersion.
It’s available in Night Black and Brown Copper, and fits standard 22mm bands, so you can swap out straps to suit your style or mood, whether you’re heading to the mountains or just grabbing a coffee downtown.




Smart tools for better workouts and recovery
At its core, the Grit X2 is driven by Polar Elixir™, their most advanced biosensing tech to date. That includes:
- 4th-gen optical heart rate
- Wrist-based ECG
- Blood oxygen saturation (SpO₂)
- Skin temperature sensing
These metrics feed into trusted Polar features like Training Load Pro, Nightly Recharge™, and the Orthostatic Test, giving you daily insight into how your body is responding to training and recovery.
For athletes who care about adaptation and performance over time, this level of physiological data is a real asset.

Offline maps, long battery life, and route confidence
Just like its pricier sibling, the Grit X2 offers full-color offline topo maps with elevation profiles and support for route points and POIs.
These maps are already preloaded with no extra steps required.
Battery life holds up, too:
- Up to 90 hours in Eco training mode
- 30 hours in full GPS Performance mode
- 7 days in Smartwatch mode
It even includes 32GB of onboard storage, and the battery is rechargeable and replaceable, something that’ll matter down the line for longevity.
Connected, customizable, and future-proofed
The Grit X2 runs on the same OS as the Grit X2 Pro, so future firmware updates, including new recovery and mapping features, will be shared across both devices.
All of your training data and routes sync through the Polar Flow ecosystem, which is well-built and gives you control over sport profiles, long-term progress tracking, and route planning.
Final thoughts
With the Grit X2, Polar has addressed a long-standing issue in the adventure watch space: most serious outdoor wearables are simply too large for those with smaller wrists.
This model strikes a great balance, rugged enough for mountain missions, compact enough for daily wear, and smart enough to support serious performance goals.
