Apple Watch Ultra 3 49mm Black Titanium with Black Ocean Band

The Apple Watch Ultra 3 (49mm Black Titanium with Black Ocean Band) is engineered for endurance athletes, ocean adventurers, and outdoor explorers facing extreme conditions. Encased in aerospace-grade Grade 5 titanium with a striking black finish and a matching ceramic and sapphire crystal back, it offers superior corrosion resistance, raised bezel edges to protect the screen, and MIL-STD 810H environmental certification.

The watch is secured by the Black Ocean Band, molded from a high-performance fluoroelastomer with a tubular geometry that stretches and flexes securely over wetsuits, held fast by a corrosion-proof titanium buckle and adjustable spring-loaded titanium loop. The front is dominated by a flat sapphire crystal display housing an Always-On Retina LTPO3 wide-angle OLED that reaches a brilliant 3000 nits peak brightness for perfect sunlight visibility and drops to 1 nit in darkness.

Driven by the Apple S10 SiP with a 64-bit dual-core processor, 4-core Neural Engine, and 64GB of storage, it powers Apple Intelligence, conversational Siri AI, and double tap/wrist flick gestures. The tactile orange Action button provides instant physical control for workout laps, waypoints, or launching a dive. Rated water-resistant to 100 meters and EN13319 certified, the watch includes a live depth gauge, water temperature sensor, and full dive computer capabilities down to 40 meters. Advanced navigation is anchored by L1 and L5 precision dual-frequency GPS, while the dual-speaker array houses an 86-decibel emergency siren audible up to 180 meters. The internal battery delivers up to 42 hours of normal use (up to 72 hours in Low Power Mode) with fast-charging support reaching 80% in about 45 minutes.
