[Help] Sync contacts from NC11 to Android Wear 2.0

Hi. I use Nextcloud 11 with Contact. Synch between Outlook, Android-Phones and Nextcloud works fine. My Problem: I just bought A ANDROID Wear 2.0 watch and this watch has a SIM-Card. So running with runtastic is fine, but now I would like to synch my contacts on that watch, so that I could use telephone without my Smartphone near. Is there a way, to synch my contacts on Android wear 2.0? Thanks for your help, sincerly, Sven

if you can get to run carddavsync or davdroid on it, then yes.
