I was initially upset I couldn't use Evernote on my brand new watch SE, but after trying Just Press Record as mentioned above I'm quite happy and find it's perfect for a watch app. The iPhone app then translates the Just Press Record recordings and can share the transcription and recording to evernote immediately.
On the watch you just tap a red button, speak, and you're done.
On your iPhone you open the app, click the Watch icon, choose the recording, share transcript and recording, add title, choose notebook, add tags done.
It's automatically transcribed and you share both to Evernote.
Hope that's helpful to anyone. Honestly, I don't care if they add an iPhone app with this effective combination and the app is like $7
