The Garmin Forerunner 55 is Garmin's most basic dedicated running watch, the entry point below the 165/255/265 models in this catalogue, aimed at beginner-to-intermediate runners who want accurate GPS pace/distance tracking and simple coaching without paying for AMOLED, maps or advanced multisport features. It has a 1.04" (26.3mm) sunlight-visible monochrome transflective MIP display at 208 x 208px, wrist heart rate, Garmin Coach free adaptive training plans, daily suggested workouts, and an always-on display that needs no ambient light sensor or battery-saving dimming the way OLED screens do. It has no touchscreen — navigation is by physical buttons only — and no on-watch music storage or smartphone-free payments. It is rated 5 ATM water resistant, in this Aqua colourway. Battery life is a strength for the price: up to 14 days in smartwatch mode with notifications and wrist heart rate active, and up to 20 hours in GPS mode. A sensible first proper running watch for someone starting structured training, with the caveat that runners wanting AMOLED, music or multisport tracking (triathlon, golf, diving, etc.) should look further up this catalogue's Forerunner or epix Pro ranges.
