The Garmin Venu 3S in Black Sesame + Slate is the smaller, 41mm-cased sibling of the Venu 3, built for buyers who want the same advanced health and fitness feature set — including ECG — in a more compact watch better suited to smaller wrists. It shares the Venu 3's bright AMOLED touchscreen and fibre-reinforced polymer case with a stainless steel bezel, but in the smaller 41mm size. Battery life is up to 10 days in smartwatch mode and up to 21 hours in continuous GPS mode — shorter than the 45mm Venu 3 simply because the smaller case holds a smaller battery. It includes more than 30 built-in indoor and GPS sport profiles (walking, running, cycling and more), Body Battery energy monitoring, sleep score and personalised sleep coaching, wrist-based heart rate, stress tracking, menstrual cycle and pregnancy tracking, guided meditation, and smart notifications for calls, texts and alerts. It connects via built-in GPS, Wi-Fi and Bluetooth, and supports on-watch music storage and Garmin Pay contactless payments. This 41mm size is the right choice for buyers who prioritise a smaller case over maximum battery life; those who want longer runtime and a larger display should choose the 45mm Venu 3 instead.
