Our take on the Apple Watch Ultra 3 [GPS + Cellular] 49mm Smartwatch
The Apple Watch Ultra 3 is Apple's largest, toughest watch: a 49mm titanium case with a flat sapphire crystal, GPS plus cellular, and a bright always-on display built for outdoor use. It adds satellite messaging for emergencies off-grid, a wider-angle OLED screen, 5G cellular and hypertension notifications alongside the diving, hiking and running tools of earlier Ultras. It suits triathletes, hikers, divers and iPhone owners who want multi-day battery and a rugged build. Against the Ultra 2 the changes are incremental, and Garmin's Enduro and Fenix lines still last longer per charge and map in more detail, while the Ultra stays the most polished smartwatch for iPhone users.
- Rugged titanium case and sapphire crystal

What reviewers say
Owners and reviewers treat the Ultra 3 as the best all-round smartwatch for iPhone users who go outdoors, praising the screen, build and satellite safety feature. Most criticism centers on its size, its battery falling short of dedicated sports watches and the modest upgrade over the Ultra 2.
- DisplayPraisedReviewers call the wider always-on screen bright and easy to read outdoors.
- BuildPraisedOwners like the titanium case and sapphire crystal, saying it shrugs off knocks.
- BatteryMixedIt lasts several days in normal use, but reviewers say heavy GPS workouts drain it faster than Garmin watches.
Questions and answers
- What is new in the Ultra 3 over the Ultra 2?
- A wider, brighter display, 5G cellular, satellite messaging for emergencies and hypertension notifications. The case, battery class and most sensors carry over.
- Does it work with Android phones?
- No. It needs an iPhone to set up and to use cellular, apps and health features.
- How long does the battery last?
- Apple rates it for multi-day use in normal mode and about a day with heavy GPS and cellular use. Low Power mode stretches it further.
- Can I swim and dive with it?
- Yes. It is rated for recreational diving to 40 meters and has a depth gauge and water temperature sensor for dive use.
- Do I need a cellular plan?
- Only for calls, messages and data when your phone is away. The watch works over GPS and Bluetooth without one.
- Is the 49mm case too big for small wrists?
- It is the largest Apple Watch, so it sits heavy on slim wrists. Try one on before buying if size matters to you.
