Score: 74/100
Garmin Forerunner 55
Score: 80/100Rankings
The Garmin Forerunner 55 is an entry-level GPS running smartwatch offering up to two weeks of battery life and a lightweight 37 g design. It lacks advanced sensors such as SpO₂ and music playback, focusing on core running features. Best for beginner and recreational runners who prioritize simplicity and endurance.
The Polar H7 is a chest-strap heart-rate sensor delivering ECG-grade accuracy and a long-lasting CR2025 battery. It lacks ANT+ support and cannot transmit data while swimming, and its older design may feel bulkier. Best suited for athletes who need precise chest-based heart-rate data and long battery life.

Professional reviewers commend the H7 for its ECG-grade accuracy, long-lasting battery, and lightweight belt design, noting its seamless Bluetooth and GymLink integration for a wide range of devices. However, they point out its legacy status, lack of ANT+ and inability to transmit data underwater, making it less future-proof than newer Polar models.
Everyday users appreciate the H7's reliable Bluetooth pairing, comfortable elastic strap, and long battery life, especially for running, gym, and swimming workouts. Recurring complaints focus on occasional pairing hiccups with non-Polar phones, strap stretch over time, and the desire for a lighter, wrist-based alternative.
Professional reviewers consider the Forerunner 55 a well-rounded, budget-friendly entry-level running watch. They commend its long battery life, clear display, and reliable wrist-based heart-rate monitoring, while noting the lack of advanced sensors and limited data customization as trade-offs for its price point.
