The Apple Watch Ultra 2 GPS + Cellular, 49mm, Titanium Case with Blue/Black Trail Loop (MRF53LW/A), in very good condition (renewed), is the ultimate sports and adventure smartwatch, offering advanced strength training features and rugged durability at a reduced price. Its 49mm aerospace-grade titanium case, corrosion-resistant and lightweight, features a sapphire crystal display for superior scratch resistance and pairs with a Blue/Black Trail Loop (S/M, fits 130-180mm wrists). At 61.4g (without band), it matches the Ultra 1’s weight, heavier than the Apple Watch Series 8 45mm (38.8g) but lighter than the Garmin fēnix 6X Sapphire (93g), balancing durability and comfort. The Always-On Retina LTPO OLED display (410 × 502 pixels, up to 3000 nits, per Apple) is 50% brighter than the Ultra 1, ensuring clarity in direct sunlight, with touch, digital crown, and a customizable Action button for instant workout control. Rated IP6X dust-resistant, 100 meters water-resistant (ISO 22810:2010, EN13319 for diving to 40m), and MIL-STD 810H tested, it’s ideal for swimming, scuba diving, and high-speed water sports. This renewed unit, professionally inspected, shows minimal cosmetic wear (e.g., minor rim scuffs, per eBay reviews), with a pristine sapphire display and battery health at 85% or higher, per Amazon.
Powered by the S9 SiP with a 64-bit dual-core processor and a lithium-ion battery, the Ultra 2 offers up to 36 hours of battery life (180 time checks, 180 notifications, 90 minutes app use, 60-minute workout with music via Bluetooth), doubling the Series 8’s 18 hours, with a low-power mode extending to 72 hours for multi-day adventures like triathlons, per Apple. Users report 2-3 days with moderate use (e.g., strength training, cycling), with one noting 50% battery after 24 hours at 80-82% starting charge. Dual-frequency GPS (L1/L5) with advanced algorithms provides the most accurate tracking among Apple Watches, ideal for distance, pace, and offline maps, per Best Buy. Strength training features include rep tracking, heart rate zones, custom workouts, and training load insights in the Fitness app, with automatic detection for exercises like squats or presses and the Action button for starting workouts or marking intervals. Advanced sensors offer ECG, temperature sensing for cycle tracking, sleep stages, and Crash/Fall Detection; blood oxygen monitoring is disabled in U.S. models post-January 2024. The double-tap gesture (watchOS 10) enables hands-free control, praised in Amazon reviews (4.7/5, 2242 ratings).
Smart features include Emergency SOS, international emergency calling, cellular calls/texts without an iPhone, Apple Pay, and 64GB for apps, music (Apple Music, Spotify), and podcasts. The Oceanic+ app (with Huish Outdoors) supports freediving with Bühlmann decompression algorithms, tracking dive parameters to 40m. Customers on eBay commend the like-new condition and 97-100% battery health, though some note non-OEM bands or chargers and titanium’s susceptibility to rim scuffs (mitigated with covers). The watch integrates with Strava, Golfshot, and Slopes, with offline maps and Compass Waypoints for hiking. Backed by Amazon Renewed’s guarantee and a one-year limited warranty, this Ultra 2 in very good condition is perfect for strength athletes seeking premium fitness tracking, durability, and connectivity.
