watchOS "1.0" and "1.0.1" are marketing versions; their true OS versions were 8.2 and 8.2.1, respectively. Since the OS version and marketing version now match as of watchOS 2.0, a fake OS version of 9.0 is specified for devices on watchOS 1.0 or 1.0.1 (watchOS 9.0 became reality in 2022).

Notes
- ^ a b Apple the build number in its mesu.apple.com listing, presumably to make the device recognize the update. (e.g. 13S344 was listed as 13S5344.) The listings on this page use the build number displayed on the device.
