Develop in ionic3 for wearable devices (Android, iOS)

I have an ionic 3 app who shown markers on a map. But now I have a new request for the app to port it to wereable devices (Android wear and Apple watch). Show the markers in a map on the watch and some info…

My app just get geometry points from webService and shown it on map. I like to reply that functionality in android wear and apple watch, just see a map with markers.

I googled a lot and I found:

I need to develop for android and iOS wereables at the time (if it is posible) with ionic 3. It is posible?

Or Do I need to develop in other platform and add the code to my compiled app?
