That's great!If you unpaired your iPhone from your Watch before updating, then it can be done, as a separate backup is saved every time the two devices are unpaired.
On your Apple Watch, go to Settings > General > Reset > Erase all Content and Settings
Wait for the watch to reset, then pair it as if it were brand new. Once paired, the app on your iPhone will ask you whether you want to set it up as new, or restore from a backup. Tap restore, and choose your watchOS 1.0.1 backup. This will downgrade the software.
It took me a whole day to figure out, but it worked!
This will only work if you unpaired your iPhone from your Apple Watch BEFORE updating to watchOS 2.0 and you must have iOS 9 installed.
