Javier's birthday is coming up and his parents are planning his present. They know he's passionate about technology and a big fan of the Apple brand. They still remember the time he stood in line in front of the MAC STORE to be one of the first to get the iPhone X.

Upon research on the Internet, Javier’s parents found out that one of the latest fashion accessories was the Apple Watch. Among other things, this watch can measure your heart rate, exercise level, give you a location via GPS, play songs and answer calls.
