Apple Watch Ultra 3 49mm Natura Titanium with Blue Anchor Ocean Band

The Apple Watch Ultra 3 (49mm Natural Titanium with Blue Anchor Ocean Band) delivers uncompromising durability, specialized water sports performance, and comprehensive wilderness safety. Crafted from raw, satin-finished Natural Grade 5 titanium paired with a ceramic and sapphire crystal back, this 49mm timepiece combines extreme structural rigidity with lightweight wear at 61.6g, fully tested to MIL-STD 810H environmental standards.

The watch comes outfitted with the Blue Anchor Ocean Band, engineered from flexible, high-performance fluoroelastomer with tubular channels that expand and contract comfortably over drysuits and thick wetsuits, secured by a lightweight titanium buckle and adjustable spring loop. Its screen is protected by a scratch-resistant flat sapphire crystal, housing an Always-On Retina LTPO3 wide-angle OLED display that delivers 3000 nits peak brightness for effortless readability in bright open-water glare, scaling down to 1 nit in the dark with dedicated red-light Night Mode watch faces.

Powered by the Apple S10 SiP with a 64-bit dual-core processor, 4-core Neural Engine, and 64GB of capacity, it supports Apple Intelligence, conversational Siri AI, and double tap/wrist flick gestures. The tactile orange Action button gives users quick physical access to workouts, dive metrics, or waypoint marking even with wet hands or heavy diving gloves. Built for aquatic exploration, it is water-resistant to 100 meters and EN13319 certified, featuring a live depth gauge, water temperature sensor, and full dive computer support down to 40 meters. Precision tracking is guaranteed by L1 and L5 dual-frequency GPS, while the dual-speaker sound system can trigger an 86-decibel emergency siren audible up to 180 meters. The battery provides up to 42 hours of normal use (up to 72 hours in Low Power Mode), supported by fast charging that reaches 80% in about 45 minutes.
