Apple has once again pushed the boundaries of smartwatch technology with the Apple Watch Ultra 3, announced on September 9, 2025, and expected to release on September 19. Designed for adventurers, athletes, and professionals who demand durability and precision, the Ultra 3 combines rugged build quality with cutting-edge features. With a titanium frame, sapphire protection, military-grade durability, and an industry-leading 3000-nit OLED display, it is Apple’s most powerful and resilient smartwatch yet.
The Ultra 3 is engineered for extreme environments. Built with a grade-5 titanium frame, sapphire crystal glass, and a ceramic/sapphire back, it offers both luxury and toughness. At 49 x 44 x 12 mm and weighing around 61.6g, it feels robust yet wearable.
It is IP6X certified for dust resistance, 100m water resistant, and 40m swimproof/diving certified under EN13319 standards. In addition, it meets MIL-STD-810H compliance, ensuring resilience against harsh outdoor conditions.
Apple equips the Ultra 3 with a 1.98-inch Retina LTPO3 OLED display, offering a resolution of 514 x 422 pixels at ~326ppi density. The highlight is its 3000-nit peak brightness, making it the brightest smartwatch display ever—perfect for visibility under direct sunlight and in extreme conditions.
Powered by the Apple S10 chipset with a dual-core CPU and PowerVR GPU, the Ultra 3 runs on watchOS 26, ensuring fluid navigation, advanced fitness tracking, and improved efficiency. With 64GB of internal storage, there’s ample space for apps, maps, and music.
Unlike standard Apple Watches, the Ultra 3 features dual loudspeakers capable of 86 decibels, making it loud enough for outdoor alerts. Connectivity options include 5G, LTE, Wi-Fi (dual-band), Bluetooth 5.3, NFC, and Ultra Wideband (Gen 2). Its GPS is enhanced with L1 + L5 support alongside GLONASS, GALILEO, QZSS, and BDS, ensuring pinpoint accuracy for outdoor tracking.
Apple has packed the Ultra 3 with next-level health and safety tools:
Safety features include Emergency SOS via satellite, making it a critical tool for explorers in remote areas without cellular coverage.
The Ultra 3 houses a Li-Ion battery that supports fast wireless charging—0 to 80% in 45 minutes. This ensures adventurers can quickly recharge before heading out.
The Apple Watch Ultra 3 starts at $799 in the United States and is available in natural titanium and black titanium finishes.
