It is still an entry level watch relative to Garmin’s other running, multisport, and GPS fitness tracking watches. But the Forerunner 55 raises the bar so high, so it gives up little. THE ESSENTIALS The Forerunner 55 is optimized as a compact running watch. It is smaller than Garmin’s other running and multisport watches and in-between the sizes of the Forerunner 45 and 45S models. It is 42mm x 42mm x 11.6mm and 37g. The screen is 26.3mm and 208 x 208 pixel resolution. Garmin does not have plans to release an “S” version of this watch.
