Key strengths
Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod, built into the watch.
The Polar Grit X2 Pro, released April 2024, is Polar's outdoor adventure GPS watch — combining 40-day battery, multi-band GPS, wrist-based running power, and sapphire glass. Polar's US list price is $999.99, or $1,099.99 for the Titan edition. Its hill splitter auto-detects climbs and descents for detailed altitude training insights. Positioned as an outdoor-first alternative to the Vantage V3.
Both are rugged multisport watches with sapphire glass, multi-band GPS, and wrist-based running power. COROS Apex 4 has full offline maps, longer GPS battery (65h on the 46mm vs 40h), a speaker and microphone, and a much lower price (from $429). Polar Grit X2 Pro has the hill splitter and Polar's training and recovery analytics. Choose COROS for maps, battery and price; Polar for its training platform.
