How to disable autocorrect on Apple Watch… - Apple Community
I'm hoping my "solution" works for you guys who are frustrated like me who don't like having auto-correct on.
Basically, in the Apple Watch app, go to General > Language & Region and change your preferred language to anything other than English. In my case, I used Filipino.
After your Watch restarts, you should find that auto-correct does not correct AS MUCH (but will still do) based on your language.
Until Apple decides to allow us to disable auto-correct, this is the best I can figure works for me.
Hope it does for you guys too.
