Hi Yel81,
We see you're looking for the QWERTY keyboard for your Apple Watch. It looks like you're using an Apple Watch Series 7 with watchOS 8, correct?
Is your device set to either English or Simplified Chinese? At this time, those are the only supported languages for the keyboard: What’s new in Apple Watch and watchOS 8
This covers how to Send messages from Apple Watch. Are you using these steps?
"Create a message on Apple Watch
- Open the Messages app
on your Apple Watch. - Scroll to the top of the screen, then tap New Message.
- Tap Add Contact, tap a contact in the list of recent conversations that appears, or choose an option:
- Tap
to search for someone in your contacts or to dictate a phone number. - Tap
to choose from your full list of contacts. - Tap
to enter a phone number.
- Tap Create Message.
- If you've set up your Apple Watch to use more than one language, tap Language, then choose a language.
Compose a text message
You can compose a message in a variety of ways—most of them on a single screen. After creating a message, tap the Create Message field, then do one or a combination of the following:
- Use the QWERTY and QuickPath keyboard: (Apple Watch Series 7 only) Tap characters to enter them or use the QuickPath keyboard to slide from one letter to the next without lifting your finger (not available for all languages). To end a word, lift your finger.
- If you don’t see the keyboard, swipe up from the bottom, then tap the Keyboard button."
Let us know! Best wishes.
