Watch6,9 Firmware Guide
The firmware history for the Watch6,9 is laid out below, split between what Apple still signs and what it doesn’t. If you’re planning a standard update or a clean restore, stick to the signed section, those are guaranteed to work with Apple’s current verification system. The unsigned section is more of an archive, useful for reference but not something most people will actually be able to install given Apple’s restrictions on older builds. Every file listed links back to Apple’s own servers.
