Buy the Apple Watch Series 11

Which Apple Watch Series 11 is right for you?

For most people, the Series 11 is the right model: it has the full set of health sensors, a display that peaks at 2,000 nits, and, according to Apple, 24 hours of battery life. On this page, you’re no longer choosing a model, but a variant. That comes down to three decisions: the case size (42mm or 46mm), the material (aluminum or titanium), and the connectivity (GPS only, or 5G as well). You can see the current prices for each variant in the overview above. Want to compare the entire lineup side by side first? You can do that on our page featuring Apple smartwatches.

42mm or 46mm: Choose Based on Your Wrist, Not Your Budget

The price difference between the two sizes is small, but the difference in how they feel on your wrist is not. The 46mm case displays more text per screen and is more comfortable when replying to messages on the go or checking your route and heart rate while exercising. On a narrow wrist, that same case sticks out and feels heavy while you sleep—even though sleep tracking is one of the very reasons to keep this watch on at night. If you’re unsure, measure your wrist circumference and compare it to the watch you’re currently wearing. That tells you more than a list of specifications.

Aluminum or Titanium

Aluminum is the lightest and most affordable option and works fine for everyday use. Titanium is more expensive and heavier, but it’s more scratch-resistant and looks more polished with a suit. Functionally, there’s no advantage: the sensors, screen, and battery life are the same. If you’re looking for a watch that can really withstand rough use, then the Apple Watch Ultra series is a more sensible way to spend that extra money.

GPS or 5G: Only Worth It If You Don’t Have Your Phone With You

The 5G version (called “Cellular” by Apple) costs extra and also requires a separate eSIM plan from your carrier. That’s worth it if you want to go running, biking, or swimming without your iPhone but still want to stay reachable. If your phone stays in your pocket or bag anyway, you’ll be paying monthly for something you don’t use. You can recognize the Cellular models by the colored ring on the Digital Crown.

What You Get in Addition to the SE 3

The difference from the entry-level model isn’t in speed: both watches use the same S10 chip. It’s in the display, the battery, and the medical sensors.

• ECG and blood oxygen: the Series 11 has an ECG app, an electrical heart sensor, and blood oxygen monitoring. The SE 3 does not have these features.
• High blood pressure alerts: the Series 11 can detect patterns that indicate high blood pressure. This is an alert feature, not a diagnosis, and it is not a substitute for a blood pressure monitor.
• Brighter screen: up to 2,000 nits peak brightness, whereas the SE 3 remains at about half that. You’ll notice the difference in bright sunlight.
• Longer battery life: 24 hours compared to 18 hours for the SE 3, and up to 38 hours in power-saving mode.
• More choices: four aluminum colors plus three titanium finishes, compared to two aluminum colors on the SE 3.

The honest downside: it needs to be charged every day

24 hours sounds like a full day, but in practice it means daily charging. If you also wear the watch at night to track your sleep, you’ll need to set aside a specific time to charge it—for example, while showering or having dinner. Fast charging helps with that (according to Apple, 80 percent in less than an hour), but it’s still a daily routine. If you want a watch that can go days or even weeks without a charger, you’re better off with Garmin. In exchange, you’ll have to do without the range of Apple apps and seamless iPhone integration.

One more thing to know upfront: an Apple Watch only works with an iPhone. If you switch to Android later, you won’t be able to take the watch with you. In that case, start by comparing the Samsung Galaxy watches.
