The Apple Watch is excellent for navigating, especially when walking around the city.
For a left turn, you'll get a series of two taps, played three times: tap-tap — tap-tap — tap-tap. For a right turn, you'll get a steady beat of 12 taps: tap-tap-tap-tap-tap-tap-tap-tap-tap-tap-tap-tap. You'll also get a long vibration when you're on your last leg of the journey, and when you arrive at your destination.
You can raise your Apple Watch or press and hold the digital crown to launch Siri.
If you are trying to capture photos without making it obvious, remember that you can use your Apple Watch to remotely control the camera app.
