The comic shows a timeline from 1990 to 2030. There's a box marked "old-fashioned dumb watches" that extends from beyond the left side of the comic to about 2005. There's another box, labelled "regular watches", that extends from about 2015 to off the right side of the comic. The text "Brief, glorious period in which our wrists were free" points to the time between regular watches and smart watches.
Title text: I don't know what we'll call non-smart watches if smart watches are actually successful, but it probably won't be "regular watches".
