Some bands containing magnets may interfere with the compass.
Magnets and compass accuracy
The presence of magnets can affect the accuracy of any compass sensor. Apple's Leather Link, Leather Loop, Milanese Loop, and earlier Sport Loop watch bands use magnets or magnetic material that might interfere with the Apple Watch compass. The compass isn't affected by Sport Loop bands introduced in September 2019 or later, or any version of the Sport Band.
Magnets in all Apple Watch models can also affect the accuracy of an external compass. If you're using another compass during activities such as diving, hiking, or navigating, keep it separated from Apple Watch when reading the external compass.
