The main 3 differences between Polar Grit X2 vs X2 Pro

The Polar Grit X2 is now official. It keeps nearly everything from the Pro model, but shrinks the footprint and price to create something more wearable.

The latest Grit X2 lands about a year after the Pro version. Polar’s been teasing it for a little over a week, and now it’s here. What’s surprising is how little has changed under the hood. There’s no new hardware, no fresh sensors, and no added features that weren’t already on the X2 Pro. The new device is about offering a refined version of what was already out there.

The launch covers Europe and several international markets, but there’s no sign of a US release for now. Polar hasn’t explained the reason, though the timing lines up with the new tariffs that could make things more difficult. In any case, the Grit X2 is positioned as a sleeker, more accessible model. Some have already started calling it the Vantage M3 in disguise, just with a tougher build.

Here are the main differences between Grit X2 and its Pro variant.

1. A smaller build

The most obvious difference is the size. The X2 Pro is a big, heavy watch. It looks serious on the wrist and feels it, too. The Grit X2 scales that back and introduces some design tweaks.

It’s still round, still rugged and with the same number of buttons. But it has a case that measures 44.7 mm across instead of 48.6 mm. Thickness is also down slightly. The regular X2 should slip under a sleeve a little easier and feel more balanced during a long run.

The weight drop is more noticeable. You go from 79 grams on the standard Pro to 62 grams on the X2. That’s a big shift. Even the titanium version of the Pro only manages 64 grams. So if you’ve held off on the Pro because of the bulk, this new version should be a better fit.

The Grit X2 display is a touch smaller at 1.28 inches versus 1.39 inches on the Pro. Resolution takes a slight hit as well, down to 416 x 416 pixels from 454 x 454. That’s not a huge loss in clarity, and the AMOLED panel should still be sharp. For most use cases, the difference probably won’t matter.

2. Tough enough for most but not quite Pro level

The new model keeps the rugged build quality. You still get the sapphire crystal display, which is a step up from Gorilla Glass found on cheaper watches. The bezel is stainless steel (so no titanium option), and the back of the case has a slightly less robust build. That’s the slight tradeoff.

Water resistance also drops from 100 metres on the Pro to 50 metres here, which might matter if you spend a lot of time in open water. Still, for the price, it hits a sweet spot.

3. Less battery but still more than enough

Battery life takes a bit of a hit. The Pro packs a 488 mAh battery while the Grit X2 drops to 310 mAh. That’s enough to cut performance mode GPS tracking from 43 hours to 30 hours. Eco training mode drops from 140 hours to 90. You still get a solid 7 days in smartwatch mode, which is fine for most people. If you’re heading out for a multi-day expedition, the Pro is still better suited. But for regular training, the cutbacks are fair.

The bottom line: More wearable, more affordable, just as capable

As you can see, not much has changed. You still get the exact same sensor suite. Polar’s Gen 4 optical heart rate, Elixir biosensing, ECG, SpO2, skin temperature, and the full multi-band GPS setup. So while the new model is smaller, everything works the same. You just get a tighter package.

The Grit X2 ships in two colors: Brown Copper and Night Black. At 480 euros, it’s not cheap, but it undercuts the euro 750 Pro by a lot. The price, weight, and materials all line up to make this feel like a practical alternative. If the Pro felt like too much, the X2 might be what you were waiting for.
