Hello. I am considering buying the apple sport version in a week or so and I have a question. They say this watch notifies you of incoming calls, if I have my iPhone on silent will the watch make a noise if there is an incoming call or message. Asking because I'm in college and some professors are strict about electronic noises in the classroom. In class I usually just shut the ringer off, curious to find out if the watch will stay silent as well. Thank you.
