Siri can also help you figure out how to reach a specific location you don't know. After you ask for the destination or get the address from Siri, the route appears on your Apple Watch under the Maps application. You can use this display to see the overview of your route, while also being able to zoom in and pan around the route you're going to take. If the location is not the one you're looking for, you can always switch it out for another option. You can do this through Apple Maps, which is one of the essential Apple Watch applications.
