The Instinct E 40mm is Garmin's smaller rugged GPS watch, built for people who want a tough outdoor watch without the bulk of the 45mm Instinct line. It has a high-strength case, scratch-resistant lens, MIL-STD-810 thermal and shock rating, and 10 ATM water resistance, plus multi-GNSS positioning, a 3-axis compass and barometric altimeter. Health tracking covers wrist heart rate, advanced sleep and Pulse Ox, with smart notifications and Connect IQ support. Against the Instinct 2S it drops some training and navigation depth but keeps the core toughness and up to 14 days of battery life.
