Since leaving Adobe for Apple in March 2013, Kevin Lynch heads a project that has been under the hood for a long time: the Apple Watch.
Lynch was recently interviewed by Mashable and addressed something that Apple commented on in the original release of its smartwatch: how much it needs in its most basic function of all, that of making an appointment. According to the executive, the Apple Watch “four times more accurate” than an iPhone in this sense.
To achieve this level of precision, the Apple Watch has hardware dedicated to maintaining and displaying the time in a very precise way, making up for even the small delays that can occur when obtaining data from the iPhone itself that pulls the current time from 15 Network Time Servers (NTPs) from Apple around the world, which use GPS coordinates to get the time directly from the United States Naval Observatory. In developing the watch, Apple used high-speed cameras to observe and fine-tune the latency of the Watch's second hand.
With all this, the Apple Watch does not differ by more than 50 milliseconds (!) From the standard universal time (Coordinated Universal Time, or UTC). To confirm this, join a group of friends who have Apple Watches and place them side by side to see how the hands are fully synchronized.
a mere curiosity, of course, but interesting. 😉
