Garmin released the Enduro 4 on October 9, 2026, pairing a solar-charging design with a 51mm titanium bezel and 64GB of storage for $899.99. The ultra-endurance GPS smartwatch retains a 320-hour battery life in solar activity mode while inheriting updated processors and software features from the Fenix 9 series.
Garmin has officially launched the Garmin Enduro 4, positioning the rugged wearable as its longest-lasting GPS smartwatch for endurance athletes, ultramarathoners, and backpackers. Arriving alongside the golf-focused Approach S72, the new model retains the physical dimensions and battery targets of its predecessor while upgrading internal hardware and tools.
Garmin Powers Enduro 4 With Solar Charging and Upgraded Mapping
Garmin rates the device for up to 36 days in smartwatch mode without solar input, stretching to 90 days when exposed to optimal solar conditions of 50,000 lux. In activity tracking with solar charging enabled, the watch reaches up to 320 hours.
Winter trail runners and athletes operating under heavy tree cover will rely on non-solar ratings, which stand at 36 days for smartwatch mode and 120 hours for extended GPS tracking. These power reserves rely on an energy-efficient 1.4-inch memory-in-pixel display paired with a solar lens, rejecting power-hungry AMOLED panels.
For GPS positioning, users can select the Extended Battery preset to achieve 120 hours—or 320 hours when utilizing solar—while the newly introduced Max Accuracy setting sacrifices some battery lifespan to deliver 60 hours of comprehensive tracking during shorter sessions.
New Garmin Watch Increases Storage and Processing Speed
The updated internal configuration includes 50% more RAM than past models, enabling a map engine that pans 30% faster and a smoother interface for built-in routable maps.
Onboard storage doubles from 32GB on the Enduro 3 to 64GB on the new release, providing additional capacity for offline maps, music downloads, and activity data. The watch also introduces a new Perspective View, giving users increased visual detail at closer and farther viewing distances to help anticipate terrain ahead.
Software Updates Add Grade-Adjusted Pacing and Multi-Day Tracking
The device introduces grade-adjusted pace-based workout targets and a real-time grade-adjusted rolling pace to assist athletes traversing hilly or mountainous terrain.
Stamina zones and a stamina curve help users monitor how their energy expenditure impacts ongoing activities. Meanwhile, a new feature called Garmin Epic consolidates performance and health information from multi-day events into a single, unified view within Garmin Connect rather than treating each 24-hour period as isolated data. Garmin points out that athletes are able to log, inspect, and share this ongoing progress, with the design goal of simplifying post-event analysis for extended journeys and multi-day competitions.
Titanium Bezel and Sapphire Lens Maintain 10 ATM Water Resistance
The Enduro 4 maintains a 51mm case constructed with a titanium bezel, a fiber-reinforced polymer case, and a scratch-resistant Power Sapphire lens. Total weight changes slightly to 66 grams due to the inclusion of Garmin’s new ComfortFit fabric band, while the watch body itself remains at 57 grams. Water resistance is rated at 10 ATM.
