Styled like a sports watch yet equipped for more hardcore pursuits, the Polar Grit X offers an impressive suite of tracking smarts and tailored training aids. Seasoned endurance athletes might be limited by the average battery life, half-baked Hill Splitter feature and lack of offline maps, but it’s still a strong option for outdoor enthusiasts looking to get more adventurous – unless you want Spotify support.
