Which Apple Watch Models Work With iPhone 13?

iPhone 13 meets the phone-model threshold for every Apple Watch in Apple’s compatibility table, but the required iOS and watchOS versions vary by model.

iPhone 13 meets the iPhone-model requirement for every Apple Watch listed in Apple’s compatibility table. The catch is software: newer watches require newer versions of iOS and watchOS, and some older watches cannot update to current watchOS. Check the exact watch model and its software requirements before buying or pairing.

Which Apple Watch models are compatible with iPhone 13?

Apple’s compatibility table, published September 17, 2026, lists iPhone 13 as meeting the phone-model threshold for every watch model shown. For the newest models, that threshold is iPhone 11 or later. The table’s software requirements still apply, so phone-model compatibility alone does not guarantee that a particular iPhone and watch can pair in their current software states.

Current models and their software requirements

Apple Watch models Minimum iPhone model Minimum iOS Compatible watchOS
Series 12, Ultra 4 iPhone 11 or later iOS 27 or later watchOS 27 or later
Series 11, SE 3, Ultra 3 iPhone 11 or later iOS 26 or later watchOS 26 or later
Series 10 iPhone XS or later iOS 18 or later watchOS 11 or later
Ultra 2, Series 9 iPhone XS or later iOS 17 or later watchOS 10 or later
Ultra, Series 8, SE 2 iPhone 8 or later iOS 16 or later watchOS 9 or later

These thresholds are from Apple’s Apple Watch and iPhone compatibility table. Apple also lists Series 7, Series 6, first-generation SE, Series 5, Series 4 (GPS and GPS + Cellular), Series 3, Series 2, Series 1, and first-generation Apple Watch. Their listed minimum iPhone models are older than iPhone 13, but software support varies by model; some older watches have a maximum supported watchOS version rather than support for current releases. Consult Apple’s table for the exact older model instead of assuming it can run the latest watchOS.

What software does iPhone 13 need?

Match the watch’s required iOS and watchOS versions to the software installed on the two devices. Apple says updating to iOS 18 requires iPhone XS or later, and updating to watchOS 11 requires iPhone XS or later running iOS 18 or later. iPhone 13 meets those phone-generation thresholds. For the newer watches in the table, verify that your iPhone can run the specified iOS version and that the watch supports the specified watchOS version.

  1. Update iPhone 13 to the iOS version required by the watch.
  2. Turn on Bluetooth and connect the iPhone to Wi-Fi or cellular.
  3. Bring the Apple Watch near the iPhone and open the Apple Watch app if setup does not begin automatically.
  4. Follow the pairing prompts and complete setup.

Apple’s guidance is explicit: “To use your Apple Watch, you need to pair it with your iPhone.” See Apple’s pairing and setup guide.

Does a cellular Apple Watch work with iPhone 13?

Yes, provided the watch and iPhone meet the model and software requirements. Cellular service is an additional setup: Apple says you can activate it during initial setup or later in the Apple Watch app. In general, the iPhone and watch must use the same carrier. Apple describes a Family Sharing exception for setting up a watch for a family member, and notes that cellular service is not available in every country or region. Check carrier and regional availability before choosing a cellular model. These ordinary pairing details should not be treated as confirmation of separate Family Setup compatibility, which has its own device and software requirements.

What to check before choosing a model

Compatibility establishes whether a watch can work with the phone; it does not determine which model is the right purchase. Once you have confirmed the software thresholds, compare the specific features you need, case size and material, GPS versus cellular, current availability, and how long the model is expected to receive watchOS support. Apple’s compatibility table specifies supported pairings and software versions, not prices or a model ranking.
