....that doesn't actually work though???
If you go to the Clock app on iPhone (iPhone 6 with latest iOS), you can ONLY delete the clocks and NOT the city symbol??
i.e. In my app, I have London, Athens and Sydney. If I delete London and then type in "Lon", but then hit "space", it just says "No Results". I have to select the "London" that the search results then show up.
Additionally, if just delete "London", from the Clock app on the phone (which I have), the abbreviation "Lon" still shows on the watch, when I choose the "World Time" complication?!!
