Set your place
The Apple Watch page cannot ask for your location, so it needs to be told. Paste a Google Maps link to the place you want, and you get a link for the watch.
1. In Google Maps, open your place, tap Share and Copy link. 2. Paste it here.
Your link for the watch:
Open itSend the link to yourself in Messages, then tap it on your watch. Or save it in a note or a Shortcut.
A short link such as maps.app.goo.gl/… cannot be read here. Open it in Safari first, then copy the long address from the address bar. Links from OpenStreetMap, or plain numbers like 52.52, 13.40, also work.
