watchOS - definition
WatchOS refers to the name of Apple's Operating System for the Apple Watch.
Over its short history, the user interface has 'pivoted' several times as Apple learns and understands how users interact with this category of device.
WatchOS is a touch based OS but is supplemented by a rotating Digital Crown that allows the user to scroll through content without their fingers obscuring the display.
