The Garmin epix Pro (Gen 2), 42mm is the smallest and most affordable case size in Garmin's premium AMOLED multisport smartwatch line, built for smaller wrists without giving up the series' full health, training and outdoor-navigation feature set. It combines a vivid 1.2" AMOLED touchscreen (390 x 390px) with the same full-colour mapping, multi-band GPS, wrist heart rate, Pulse Ox, HRV status, sleep coaching, Garmin Pay, on-watch music storage (up to 2,000 songs via Spotify/Amazon Music/Deezer), and a built-in adjustable LED flashlight found across the whole epix Pro range. This Glass Edition pairs a Corning Gorilla Glass DX lens with a passivated stainless-steel bezel and a Whitestone-coloured case, and is rated 10 ATM water resistant. Battery life is the trade-off for the compact size: up to 10 days in smartwatch mode with gesture wake (dropping to about 4 days with the always-on display enabled), around 21 hours with all satellite systems active, or 13 hours with multi-band GPS enabled — noticeably less than the 47mm and 51mm models, which use larger batteries to run considerably longer. Best suited to someone who prioritises a smaller, lighter watch over maximum battery life; anyone doing very long multi-day activities should look at the 47mm or 51mm epix Pro instead.
