Garmin Forerunner 55 vs 165 – Check Which One Is Best & Why?

Garmin Forerunner 165 & Garmin Forerunner 55 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Garmin Forerunner 165 rather than the Garmin Forerunner 55. 

Why Do I Recommend The Garmin Forerunner 165

  • The Garmin Forerunner 165 comes with a 1.2-inch AMOLED touchscreen for vivid color, sharper readability, and intuitive touch control during workouts, while the Garmin Forerunner 55 uses a 1.04-inch transflective MIP display.
  • Garmin Forerunner 165 supports onboard music storage for phone-free listening during runs, whereas the Garmin Forerunner 55 can only control music playing on a connected smartphone.
  • It includes a Pulse Oximeter for continuous blood-oxygen monitoring and altitude acclimation insights, while the Garmin Forerunner 55 lacks a dedicated SpO₂ sensor.
  • The Garmin Forerunner 165 features advanced running dynamics such as vertical oscillation, ground contact time, and stride length for detailed performance analysis, whereas the Garmin Forerunner 55 provides only basic running metrics like pace and cadence.
  • Garmin Forerunner 165 supports course navigation with turn-by-turn guidance and back-to-start routing for safer outdoor exploration, while the Garmin Forerunner 55 limits users to simple GPS tracking without on-watch route guidance.
  • It includes nap detection and enhanced sleep scoring for more precise recovery tracking, whereas the Garmin Forerunner 55 provides only standard sleep stage monitoring without nap detection.
  • The Garmin Forerunner 165 supports Garmin Pay for convenient contactless payments during runs or errands, while the Garmin Forerunner 55 has no contactless payment functionality.
  • Garmin Forerunner 165 comes with a brighter, always-on display mode for quick glance visibility in all lighting conditions, whereas the Garmin Forerunner 55 relies on a non-always-on screen that requires a button press or wrist gesture to view.

Maybe the Garmin Forerunner 55 price can make you comfortable because it’s a little bit cheaper than the Garmin Forerunner 165. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
