Apple Watch Ultra 3 - 49mm - GPS + Cellular

The Apple Watch Ultra 3 is a rugged, high-performance smartwatch designed for adventurers, athletes, and users who want top-tier features and durability. It is equipped with a 49 mm Grade 5 titanium case, offered in Natural and Black finishes. A large Always-On Retina display using LTPO3 and wide-angle OLED panels is used, delivering very high brightness and improved visibility from various angles. The display borders are made about 24% thinner compared to previous Ultra models so that more screen area is available without increasing the case size. Cellular + GPS connectivity is supported, with a new 5G modem and advanced antenna architecture so signal strength is improved, especially in weak-coverage zones.

Battery life is extended significantly: up to 42 hours in normal use, and up to 72 hours in Low Power Mode. For outdoor workouts and GPS usage, the watch is able to run long hikes, long sessions, or adventure usage with reliable tracking and location performance. Features like built-in satellite communication are now included, enabling Emergency SOS or location sharing when off the grid without WiFi or cellular. Health-related insights have been further strengthened, with new hypertension alert notifications and a Sleep Score function helping users monitor cardiovascular risk and sleep quality using sensors on the watch and data aggregated in the Health app.
