The Expert Summary
The Polar Pacer Pro is a lightweight, running-focused watch known for accurate GPS and reliable heart rate tracking, especially during steady and structured runs. Its training load, recovery, and running power metrics provide meaningful insights without unnecessary complexity, making it well suited for performance-driven users who want clean, actionable data rather than smartwatch extras. Comfort is a standout, allowing for all-day and long-run wear without irritation.
The main drawbacks are software stability concerns and average battery life. Some users experience occasional system resets, and real-world battery performance often falls short of expectations compared to similar competitors.
The Trusted Verdict
"A strong choice for runners who prioritize accuracy, comfort, and focused training metrics. Less ideal for those who need maximum reliability or long battery life above all else."
