Apple Watch Ultra 3 (49 mm) Specs
Identifiers: Watch Ultra 3 - MEWK4LW/A* - Pending - A3281* - 8911*
All Apple Watch Models
Please note that Apple states Apple Watch Ultra 3 models "have been optimized for use in the country of purchase, and not all models work in all countries or regions. There is no single model that supports cellular service worldwide." Although the hardware is capable of using 5G, it is not supported everywhere. Specific cellular support varies based on location sold.
The Apple Watch Ultra 3 models are highly similar to their predecessors -- and remain targeted to those interested in a large, rugged watch for sports and outdoor activities -- but have a larger and better quality display in the same size housing, longer battery life, 5G capability, and Emergency SOS via satellite.
All Apple Watch Ultra 3 models are capable of being connected to the Internet without a "tethered" iPhone, but it still is intended to be used with an iPhone 11 or later running iOS 26 or later for some functions.
Each Apple Watch Ultra 3 device is controlled with a Digital Crown with haptic feedback and a touch capable display in addition to two buttons -- a silver one beneath the Digital Crown and an orange "Action" button on the opposite side of the housing. All Apple Watch Ultra 3 models use a 49 mm housing and feature a 422x514 "Always-On Retina" LTPO3 OLED screen protected by flat sapphire crystal glass and packed in either a "Natural" or Black Titanium case. The ceramic charger on the back is protected by sapphire crystal, too.
Battery life is an Apple estimated "up to 42 hours" overall in "normal" use; the "Low Power Mode" option can extend battery life to up to 72 hours by disabling some functionality, as well.

Apple notes that the Apple Watch Ultra 3 models "have been optimized for use in the country of purchase, and not all models work in all countries or regions. There is no single model that supports cellular service worldwide."
Apple formally segments this model into three categories -- one for the United States, Canada, Ecuador, Mexico and Puerto Rico; another for 58 countries worldwide, and a third for Hong Kong and Macao, but all appear to have the same A3821 model number and same 8911 EMC Number. Apple also no longer provides specifics regarding 4G LTE and 5G bands that are supported in different locations. The assumption is that the underlying hardware is the same, but compatibility and functionality vary by location. Nevertheless, this is subject to confirmation (Pending).
Although Apple does not provide specifics regarding cellular band support, government compliance documents indicate that it was tested in the United States on 5G bands n2, n5, n7, n12, n14, n25, n26, n41, n53, n66, n71, and n254 as well as LTE bands 2, 4, 5, 7, 12, 13, 14, 17, 25, 26, 41, 53, 66 and 71. |
