I've been having this too, since the watchOS 10 upgrade. (I skipped 10.0 and went straight to 10.1.) Seems intermittent but really annoying when it does happen. I've been able to "fix" it (for a while) by going to Settings → Messages on my phone, going to Notifications, and toggling it off and back on again.
I know my watch "knows" about the messages that come in even when the notification doesn't pop up. If I open the Messages app, they are right there, with the little unread blue dot.
Hoping 10.2 fixes it, supposed to be released sometime next week. I really should wait longer before doing these major OS upgrades.
