Polar H9
Score: 83/100
Coros PACE 3
Score: 84/100Rankings
The COROS Pace 3 is a performance-focused sport watch with dual-frequency GPS, up to 15 days of daily battery life, and a bright AMOLED display. Its bulkier build and lack of on-watch audio may deter some users. Best for serious runners and triathletes needing precise navigation and long endurance.
The Polar H9 is a chest-mounted ECG heart-rate sensor offering exceptional accuracy and a 400-hour battery life. Its main trade-off is the lack of onboard storage and reliance on a replace-once coin cell battery. Ideal for athletes who need precise data across multiple sports and appreciate dual-protocol connectivity.

Editors and CrossFit-focused reviewers consider the Polar H9 the best-value chest strap, emphasizing its precise ECG tracking, dual-protocol connectivity, and underwater capability.
Professional reviewers commend the COROS Pace Pro for its industry-leading battery life, robust offline mapping, and advanced health sensors, positioning it as a premium navigation-centric tool for serious athletes. However, they point out its bulkier profile, lack of built-in audio hardware, and limited on-watch music controls as trade-offs compared to higher-priced competitors.
Consumers overwhelmingly appreciate the watch's long battery endurance, lightweight comfort, and accurate multi-sport tracking, often citing the 360-hour mixed-use battery as a game-changer. Recurring frustrations revolve around occasional heart-rate sensor glitches, the missing charging cable, and the wrist-size limitation.
“"Battery lasts "360 hours" in mixed use; lightweight (30-49 g) and comfortable for runs/sleep; accurate multi-sport tracking (run/bike/swim/strength), easy Android pairing and music playback."”
“"Take your running watch to the next level... premium tool to pace you through epic excursions."”
