Desk-review verdict: The Polar Grit X2 Pro is a premium outdoor multisport watch for trail runners, ultrarunners, hikers and mountain athletes who value mapping, recovery insight and rugged construction. At Polar Australia’s listed price of AU$1,099, it makes most sense for committed outdoor athletes—not beginners seeking simple pace and distance.

Why it belongs on a mountain athlete’s shortlist
The Grit X2 Pro’s appeal is not one party trick. It is the combination of a bright AMOLED display, sapphire lens, dual-frequency satellite positioning, offline maps and substantial claimed training battery life. That is a serious toolkit for a long trail race, a multi-day hike or a winter day where navigation matters more than notifications.
Polar also lists WR100 water resistance and testing against MIL-STD-810H conditions. Those specifications broaden its usefulness beyond running to hiking, walking, cycling, swimming and snow sports. Rugged does not mean indestructible, of course; Polar’s care and operating guidance still applies.
GPS and navigation
Dual-frequency GPS can reduce errors caused by reflected signals around cliffs, buildings and dense terrain, although real-world performance always depends on satellite geometry, surroundings, fit and current firmware. We therefore rate the navigation package highly on specification, without presenting laboratory accuracy numbers we have not measured.
Offline maps, breadcrumb guidance, compass and barometric elevation are especially relevant for trail and ultra use. Download maps and planned routes before leaving coverage, and carry the safety equipment and navigation backup required by your event or environment. A watch is useful navigation assistance, not a substitute for sound mountain judgement.
Heart rate, recovery and health sensors
Polar equips the watch with its Generation 4 optical heart-rate system plus ECG, blood-oxygen and wrist skin-temperature sensing. These features can enrich training and recovery trends, but wrist readings are not medical diagnoses and may be affected by movement, temperature, skin contact and placement. A compatible chest strap remains the stronger option when an athlete needs more stable heart-rate data during hard intervals or in cold conditions.
Battery: strong, with important caveats
Polar claims up to 43 hours in performance training mode, 140 hours in eco training mode and 10 days in smartwatch mode. These are manufacturer figures, not our measured results. AMOLED brightness, always-on display, map use, satellite mode, notifications, temperature and battery age can all change actual endurance.
For a standard marathon, trail marathon or most supported ultras, the performance-mode claim provides a healthy planning margin. Athletes targeting very long events should test their exact settings in training and understand how eco modes trade recording detail for endurance.
Running, hiking, skiing and gym use
- Marathon training: powerful, though heavier and more expensive than necessary for road-only runners.
- Trail and ultra: the clearest match thanks to mapping, elevation tools and battery options.
- Hiking and walking: excellent feature fit where maps, weather awareness and durable construction matter.
- Skiing and outdoor multisport: useful sensor and profile coverage, with cold-weather battery planning still essential.
- Gym and indoor training: capable, but its rugged hardware and mapping premium are largely wasted indoors.
- Triathlon: a credible multisport option; athletes should confirm that current sport profiles and transition workflow match their race needs.
Who should buy it?
Buy the Grit X2 Pro if your training calendar includes trails, mountains, navigation-heavy adventures or long events and you want Polar’s recovery ecosystem in a premium outdoor case. A newer runner focusing on 5 km, fun runs and general fitness will receive better Australian value from a lighter, less expensive running watch.

Frequently asked questions
Is the Polar Grit X2 Pro good for beginners?
It is usable, but usually poor value for a beginner who mainly needs reliable GPS, pace and basic training guidance. Its strongest benefits are mapping, ruggedness and long-adventure features.
Can it last a marathon?
Polar’s claimed 43-hour performance-training figure is far beyond typical marathon duration. Actual battery life varies, so test race-day settings beforehand.
Can it be used for hiking and skiing?
Yes. Its maps, compass, barometer, water resistance and outdoor sport coverage make hiking and snow sports natural secondary uses.
Does ECG make it a medical device?
No. Treat wrist ECG and other wellness measurements as training context, not diagnosis. Seek advice from a qualified health practitioner for medical concerns.
