What owners say about the Polar Grit X Pro

Based on 45 owners sharing their experience in online comments

33%positive16%mixed51%negative

Owners value its training features and Polar app, but poor screen readability, unreliable controls, and inconsistent activity data stand out.

What owners dislike

  • Activity data is inaccurate or missing6
  • The screen is dim even at maximum brightness and hard to read, which made some buyers return the watch.4
  • The touchscreen often stops responding to swipes, and some owners report the buttons jamming after about three years of use.4
  • Live widgets such as weather and sunset cannot be opened during an outdoor activity, and there is no separate climbing mode for switching between hiking and climbing.4
  • During a hike, live coordinates can't be shown without ending the activity, and navigation only starts when standing exactly on the route's start point.3
  • Owners report the frame picks up scratches despite the scratch-proof claims, and buttons can jam after heavy use.3
  • Turning the watch off is hard to find in the settings, and new wearers say the controls take time to learn.3

Points mentioned by at least 3 owners, most mentioned first.

Verdict

The Polar Grit X Pro is a premium outdoor multisport watch engineered for extreme durability, featuring a 47mm stainless steel case, scratch-resistant sapphire glass, and MIL-STD-810G military-grade testing with 100m water resistance. Key specifications include a 1.2-inch always-on transflective memory-in-pixel (MIP) display (240x240 resolution), a 346 mAh battery providing up to 40 hours of full GPS/HR tracking or 7 days in watch mode, and advanced sensors for barometric altitude and Polar Precision Prime heart rate monitoring. Main pros include its rugged build, reliable turn-by-turn navigation via Komoot, and comprehensive recovery tools like Nightly Recharge and Leg Recovery tests. However, notable cons include a sometimes laggy touchscreen interface, the lack of internal music storage or contactless payments, and a display that can appear dim indoors compared to modern AMOLED competitors.
