Set Google Messenger as default watch text app?

[Lexamundo]

Google Messenger now has a watch companion app but I can't see a way to set it as the default watch text app on my ZW2. It only seems possible to use GMessenger on the watch to read messages that initially came through the stock Android Wear messaging app and for sending of outgoing messages.

Not sure I understand your question... The watch will typically use whatever app the original notification came in under (assuming that app supports Android Wear, of course).

If you want Google messenger to be the default app when sending an unsolicited SMS (in other words, not a reply... But initiating a new text message), this usually goes by whatever app is set on the phone as the default SMS app.
