Apple Watch Ultra 3 vs Garmin Enduro 3

Encased in 49mm aerospace titanium with a flat sapphire crystal, 3,000-nit wide-angle LTPO3 OLED display, and EN13319 40-meter dive certification, the Apple Watch Ultra 3 is the most capable smartwatch Apple has ever built. Dual-frequency L1+L5 GPS tracks urban marathons with surgical accuracy and 36-to-72-hour battery life comfortably clears weekend adventures, making it the definitive choice for iPhone athletes who want one watch for the trail and the boardroom.

Engineered specifically for 100-mile ultramarathoners and thru-hikers, the Garmin Enduro 3 packs a high-efficiency Power Sapphire solar collar, 32GB TopoActive maps, Elevate Gen 5 ECG sensors, and an LED torch into a 63-gram 51mm titanium chassis. Reaching up to 320 hours of solar-assisted GPS tracking and 90 days of smartwatch use—while costing $100 less than the Fenix 8—it is an endurance masterpiece.
