The Garmin Forerunner 255 Music is a mid-range GPS running watch for serious runners and multisport athletes, sitting between the entry-level 55/165 and the AMOLED 265/965 models in this catalogue. It has a 1.3" sunlight-visible transflective colour MIP display at 260 x 260px, wrist heart rate, running dynamics and power via the wrist, training readiness, HRV status, daily suggested workouts and Garmin Coach — a genuinely training-focused watch rather than a simple activity tracker. As the Music variant it adds around 8GB of on-watch storage (roughly 500 songs) with Wi-Fi for downloading playlists from Spotify, Amazon Music or Deezer, plus Bluetooth headphone support, so runners can train phone-free — the Basic (non-Music) Forerunner 255 in this catalogue drops that storage and is otherwise identical. The case is fibre-reinforced plastic with a Corning Gorilla Glass 3 lens, rated 5 ATM water resistant, in this Whitestone colourway. Battery life is up to 14 days in smartwatch mode and up to 30 hours with GPS running continuously, dropping to around 7 hours with GPS and on-watch music playing together. A strong pick for a runner who wants Garmin's full running-science feature set, excellent battery life, and phone-free music.
