GPS performance of a Forerunner 955 is better because of the multi-frequency positioning sensor. Forerunner 955 sensor for multi-band GPS allows you to fetch GPS data from multiple satellites at the same time.

This improves the accuracy of GPS data.

Additionally, Forerunner 955 has SatIQ technology to toggle between multi-mode GPS and simple GPS automatically. It helps in conserving battery because SatIQ will initiate multi-mode GPS if the quality of GPS data is not good at a specific location.

For the multi-mode GPS availability, Forerunner 955 must be preferred over the Fenix 7. Especially, if you are serious about your running regime and tracking of activity data.

Water rating

Fenix 7 has a water rating of 10 ATM and Forerunner 955 has a water rating of 5 ATM.

10 ATM rating means that the watch can sustain pressure equivalent to 10 atmospheres. In other words, the Fenix 7 watch can handle the depth pressure of water at 100 meters depth below the water surface level.

5 ATM rating means that the watch can sustain a depth pressure at under 50 meters below the water surface level.

5 ATM and 10 ATM ratings imply that the Fenix 7 and Forerunner 955 can be used while swimming.

Both watches come with in-built profiles for swimming. The profiles include pool swimming and open water swimming.

However, we do suggest that Fenix 7 and Forerunner 955 must not be used for deep water sports or activities. Also, both watches must be avoided for snorkeling.

Other Miscellaneous features

There are some trivial features that are different between the Fenix 7 and Forerunner 955 smartwatches. We list some of these below.

  • Forerunner 955 supports the safety feature of spectator messaging. Live Track followers can send you text or audio messages through the spectator messaging feature. Spectator messaging uses your paired smartphone’s network connectivity to get the messages.
  • Forerunner 955 can send relaxation reminders.
  • Cardio workouts are available on Fenix 7. Forerunner 955 lacks cardio workouts.
  • Fenix 7 has additional profiles for cycling and outdoor recreation.


  • Forerunner 955 costs $499.99
  • Fenix 7 standard edition comes for $699.99

You can see that the difference in the list price of Fenix 7 and Forerunner 955 is $200.

The incremental cost of Fenix 7 can be attributed to the additional mult-frequency sensor and better display screen of the watch.

Final verdict

The choice between Fenix 7 and Forerunner 955 would depend upon your end goals.

For runners, Forerunner 955 is better as it has multi-mode GPS and DX coated Corning Gorilla Glass 3 for improved display readability while you are outdoor.
