Watches have always been a status symbol after their primary function of telling time.

You keep your phone in your pocket, but a watch is there for all to see, is it an expensive Rolex? A cheap Casio? A fruit watch, connected to a fruit phone? Or something that looks like that device from the begining of Spy Kids 2 that I still want 20+ years later.

Function then fashion, and its always kept up with the tech of the time, all they way back to the chronometer.
