Garmin announced the Enduro 4 on October 6, 2026, its latest ultra-endurance GPS smartwatch. Priced at $899.99 in the US with sales starting October 9, the watch keeps the same price as its predecessor while doubling storage to 64GB and adding 50% more RAM.
The Enduro 4 carries the same launch price as the Enduro 3 from 2024, a rarity noted by reviewers given rising memory prices. It comes in a single 51mm size with a titanium bezel, weighs 66 grams, and ships with a ComfortFit fabric band. In Malaysia, it is priced at RM3,899 with sales beginning October 30.
The watch keeps the 1.4-inch MIP display (280×280) with a Power Sapphire solar lens. Garmin claims up to 90 days of battery life in smartwatch mode and up to 320 hours of GPS activity tracking with solar charging. Two new power modes, Max Accuracy and Max Battery, let users trade tracking detail for runtime. An LED flashlight and 10 ATM water rating round out the hardware.
Storage jumps from 32GB to 64GB, making room for offline maps, local music, and apps. The 50% RAM increase makes map panning 30% faster, according to Garmin. A new Perspective View lets users look further ahead along their route.
New training features include grade-adjusted workout targets and rolling pace, which correct pace for hills, plus Stamina Zones and a Stamina Curve showing how energy reserves change during or across activities. Garmin Epic stitches days, weeks, or months of activity into a single story with photos and health summaries. Rowing and ruck (weighted backpack) tools join a roster of more than 100 sport profiles.
The Enduro line targets ultra-runners, backpackers, and multiday expedition athletes. Susan Lyman, Garmin's vice president of consumer sales and marketing, said the watch is for athletes and adventurers "who want gear they can trust to perform through every mile, every climb and every challenge." Unlike the Fenix 9 series, the Enduro 4 skips satellite messaging and dive mode, staying focused on maximum runtime.
The 320-hour figure assumes steady, strong sunlight, so real-world results will vary. With the Enduro 4 and Fenix 9 side by side, buyers choose between extreme endurance and a fuller smartwatch feature set, including whether they need satellite connectivity or are willing to trade the AMOLED screen for solar longevity.
