Apple Watch Ultra 4 dupes and alternatives: 7 cheaper adventure watches, scored
The Apple Watch Ultra 4 is the adventure watch most iPhone owners look at first, at $799. Apple publishes a full sheet: dual-frequency GPS, offline maps, a sapphire lens, 100 m water resistance, an ECG app and cellular on every model, in a 63 g titanium case. The weak spot is battery: 50 hours of normal use and 18 hours of GPS workout tracking, where every rival below lists more.

How this page was scored
Every watch here has built-in GPS and a case made for the outdoors; the gaps that matter on a trail are narrower. How long it runs as a smartwatch and how many hours it records in its most accurate GPS mode, whether it uses dual-frequency GPS, whether it carries maps you can follow offline, whether it has a flashlight and a sapphire lens, how deep it is rated, and whether there is an ECG or a cellular version.
Specs are weighted by how much they matter for a adventure watch. An alternative earns full credit for matching or beating the Apple Watch Ultra 4 on a spec, a proportional share where it falls short, and half credit for a spec its maker does not list. Models that list too few specs to compare fairly are left off. Read the full method.
Savings use maker or named-retailer list prices on the date shown. Amazon prices, where shown, are labelled with the time they were fetched. Spotted an error? Tell us.
