Apple Watch Ultra 4 GPS + Cellular 49mm Titanium Case with Alpine Loop
The Apple Watch Ultra 4 GPS + Cellular 49mm Titanium Case with Alpine Loop is Apple’s premier adventure and endurance smartwatch, built for hikers, trail runners, and alpine explorers. Engineered with a rugged aerospace-grade Grade 5 titanium case and a protective flat sapphire front crystal, it houses an ultra-bright Always-On LTPO3 OLED display capable of reaching 3,000 nits peak brightness for clear visibility in harsh high-altitude sunlight. Paired with the iconic Alpine Loop—woven from two textile layers fused together into a continuous piece without stitching, featuring a corrosion-resistant titanium G-hook that slips smoothly into reinforced top loops for a secure fit—this watch is built to stay comfortably anchored through tough climbs and long expeditions. Powered by the advanced S11 SiP with Apple Intelligence, the Ultra 4 delivers precision dual-frequency GPS, extended multiday battery life of up to 50 hours, and a comprehensive suite of outdoor navigation, altitude, and health-tracking sensors.
- 49mm Grade 5 Titanium Case: Lightweight, rugged, and corrosion-resistant aerospace titanium construction tested to MIL-STD 810H environmental standards.
- Alpine Loop Band: Jointless, high-strength double-layer weave with top loops and a titanium G-hook for a rock-solid, comfortable fit on demanding trails.
- Ultra-Bright 3,000-Nit LTPO3 Display: Flat sapphire crystal glass over an edge-to-edge wide-angle OLED screen for maximum legibility in direct sun or high elevation.
- Precision Dual-Frequency GPS: Integrates dual-band L1 and L5 GPS (supporting GPS, Galileo, QZSS, and BeiDou) to maintain accurate route tracking and elevation data in dense forest canopy or steep rock faces.
- Advanced S11 Chip & Health Sensing: S11 processor with 4-Core Neural Engine powers on-device Siri, Apple Intelligence features, and advanced sensor tracking for heart rate, wrist temperature, and vital signs.
