"The Apple Watch keeps perfect time."
Perfect time?
Really?
Time is relative.
The clock chip in the watch is cheap and probably has a bit of skew.
It works well enough because it syncs to the iPhone. Who also has a bit of skew in their cheap clocks.
But it works ok, because it occasionally syncs with the cell towers which have much better clocks which are more accurate.
Good base station clocks have both GPS and Radio antennas to connect to the radio clock signal from a known site and along with knowing their GPS coordinates they are able to sync properly to the time signal and then keep track of the time and its internal skew.
And of course there are differences in terms of the types of clocks and their relative accuracy.
I guess what you meant to say was that your iWatch keeps time well enough that your girlfriend doesn't yell at you for being late. ;-)
