First generation Apple Watch units with a bloated battery now have three-years of warranty protection23
Apple products with a swollen cell are usually given an extended two-year limited warranty, one year beyond the regular one-year warranty length. According to the internal document, Apple is adding a second free-year to owners of the first-gen Apple Watch with a bloated battery.
While OG Apple Watch users experiencing the battery swelling have posted about it on the Apple support forum and on Reddit, this is an issue that hasn't received much press prior to today's leak. If you own a first-gen Apple Watch, just know that Apple will honor the limited warranty if you bring it in for repair within three-years from the date that you purchased the device.
