Apple only sells three Apple Watch lines, so this decision is simpler than it looks. Each line gets updated every so often, but the roles stay the same: one cheap, one for most people, one tough and expensive. Pick the role first, then buy the newest version of it you can afford.
| Apple Watch SE | Apple Watch Series | Apple Watch Ultra | |
|---|---|---|---|
| Who it’s for | First-timers, kids, budget buyers | Most people | Outdoor, endurance, battery lovers |
| Price tier | Lowest | Middle | Highest |
| Battery | About a day | About a day | About two days or more |
| Health extras | Core health and safety features | Adds advanced sensors like ECG | Everything, plus outdoor features |
| Size | Smaller cases | Two sizes | One large size |
Apple Watch SE: the smart starter watch
The SE has the features most people use every day: notifications, Apple Pay, workouts, sleep tracking, heart rate alerts, fall detection and crash detection. It skips some of the advanced health sensors. If you’ve never owned a smartwatch, start here. It’s also the go-to watch for kids using Family Setup, which our kids GPS smartwatch guide covers.
Apple Watch Series: the one most people should buy
The Series gets Apple’s newest health sensors first, including ECG, a brighter always-on display, faster charging and more case materials. If health tracking is a big reason you want a watch, the step up from the SE is worth it. Choose the larger size if you want a bigger screen and slightly more battery, the smaller one if you have slim wrists or want it lighter for sleep.
Apple Watch Ultra: for adventures and battery life
The Ultra is huge, tough, very bright, and lasts roughly two days or more per charge. It adds an extra action button, a dive-ready build, a louder siren and stronger GPS. It’s brilliant for hikers, divers and endurance athletes, and plenty of people buy it just to charge less often. For a desk job and a daily walk, though, it’s more watch than you need.
GPS or GPS plus cellular?
GPS-only watches need your iPhone nearby for calls and texts. Cellular lets you leave the phone at home and still call, text and stream music, but it costs more and needs a monthly carrier plan. Get cellular if you run without your phone, for kids, or for a parent who might need to call for help.
Should you buy an older model on sale?
Often, yes. Last year’s Series at a real discount is usually a better deal than this year’s SE. Just make sure it still runs the current version of watchOS, since older models eventually lose updates. Our guide on how to tell if a smartwatch deal is actually good walks through that.
My take
Buy the SE for a first watch or a kid. Buy the Series if you care about health features. Buy the Ultra only if you’ll use the toughness or love the battery life. Comparing with Fitbit instead? Read our Apple Watch vs. Fitbit breakdown.
