Apple Watch Ultra 2 Review: 9.1/10 - The ultimate sports watch gets brighter and faster
Overview
The Apple Watch Ultra 2, released in September 2023, is Apple’s most capable wearable, designed for athletes, divers, and outdoor adventurers. It features the S9 SiP chip for faster on-device processing, a 3000-nit display that is the brightest Apple has ever made, and dual-frequency GPS for improved accuracy in challenging environments. The 49mm titanium case and sapphire crystal display are built for extreme conditions.
Design & Build
The Ultra 2 retains the bold 49mm titanium case with the signature orange Action Button and raised bezel protecting the sapphire crystal display. The flat screen is protected by a sapphire crystal that resists scratches exceptionally well. The Digital Crown has larger ridges for use with gloves, and the second speaker grille improves call and siren volume. The new Modular Ultra watch face takes advantage of the display’s edge-to-edge design. Build quality is exceptional, with MIL-STD 810H certification for shock, heat, and altitude resistance.
Performance
The S9 SiP delivers noticeably faster app launches and smoother animations than the first Ultra. The 3000-nit display is incredibly readable in direct sunlight, and the 1-nit minimum brightness is comfortable in dark conditions. Dual-frequency GPS (L1 + L5) provides superior tracking accuracy in urban canyons and dense tree cover. The precision dual-frequency GPS significantly improves distance and route accuracy for running and hiking. Battery life reaches 36 hours of normal use and up to 72 hours in low-power mode. The 64GB storage provides ample room for offline music and maps.
Features
The Action Button is customizable to launch workouts, waypoints, backtrack, or any shortcut. The depth gauge and water temperature sensor support recreational diving to 40 meters. Siri can process requests on-device for faster responses and improved privacy. Precision Finding with iPhone 15 uses the UWB chip for accurate location. The 86-decibel siren can be heard up to 600 feet away. Crash Detection and Fall Detection provide safety features for solo adventures. watchOS 10 brings redesigned apps, Smart Stack, and new cycling and hiking metrics.
