Thanks for reaching out to the Apple Support Communities. To get started, we do want you to be aware that the Apple Watch SE (1st Generation) would not be compatible with the QWERTY and QuickPath keyboard.

This feature would only be available on be available on the Apple Watch Series 7 and Apple Watch Series 8. You can find this information listed in the following resource under the "Compose a message" section: Write and reply to mail on Apple Watch - Apple Support

We hope that's able to help.
