The Apple Watch Notification Sound was Made by hitting an Apple Watch

File this under interesting, at WWDC 2017 Apple had a stage demonstration about sound design and at 17:45 in the linked video the sound designer actually revealed that the alert sound for the Apple Watch was designed by tapping the structure of an Apple Watch with a percussive stick.

Also included in the video are other live performance demonstrations how actual iOS sounds were made. If you are a hard core Apple trivia nerd, this is a great video to watch.
