Watch6,3 Firmware Guide
If you’re looking for firmware options for the Watch6,3, this is the full list, straight from Apple’s own release history. The signed builds are what you’d use for a normal update or restore right now, since those are the only ones Apple’s servers will still accept. The unsigned ones further down are kept mostly for reference, since actually installing them again usually isn’t possible once Apple moves on to a newer version. Either way, nothing here is hosted on our end, every link goes directly to Apple, so what lands on your device is the untouched original file.
