The Garmin Venu 3 in Black + Slate is a 45mm everyday health and fitness smartwatch aimed at buyers who want advanced wellness tracking (including ECG) alongside a bright AMOLED display and phone-call support from the wrist. It has a 1.4-inch AMOLED touchscreen protected by Corning Gorilla Glass 3, set in a fibre-reinforced polymer case with a stainless steel bezel. Battery life is up to 14 days in smartwatch mode, extending to up to 26 days in battery saver mode, with up to 26 hours in continuous GPS mode. Health features include Body Battery energy monitoring, sleep coaching, HRV status, skin temperature tracking, ECG, Pulse Ox blood oxygen monitoring and stress tracking, on top of more than 30 built-in sport profiles. It has on-watch music storage compatible with Spotify, Deezer and Amazon Music, Garmin Pay contactless payments, and a built-in speaker and microphone for phone calls and voice assistant access. It's water rated to 5 ATM, suitable for swimming and everyday water exposure. This 45mm size suits buyers who want a larger display and case; those who prefer a smaller wrist profile should choose the Venu 3S instead — both share identical smartwatch-mode software and features.
