Do you need to upgrade?

It depends on which watch you want to upgrade. If you have a multisport GPS watch, such as the Garmin Forerunner 920XT, TomTom Multisport GPS or Suunto Ambit3 Sport, or an outdoor watch like the Garmin fenix, or epix, or Suunto Ambit2 or Ambit3 Peak, you miss the Swim, Cycling, hiking and other outdoor features.

If you use a Forerunner 220/620 or similar GPS-running watches from Suunto and TomTom, you want to track activities and receive smart notifications from your phone, then upgrading to the Garmin Forerunner 630 is a good step. The Forerunner 630 is Garmin's newest GPS watch. It's Garmin's most advanced running-specific watch.

However, if you only need the core features of a GPS watch and do not need phone calls and advanced loop dynamics, models like the Garmin Forerunner 220/620, Suunto Ambit2R, or TomTom Runner GPS would work well. . Although these running watches do not have any new features on the new models, they are still good choices for runners.
