The results would have stayed on the watch face until the batteries died. But trying to make time stand still this way would have been a mistake. It is just as important to erase times eventually as to save them at first.

The natural urge when running a distance is to push harder and finish sooner - to race against time. Every second behind a deadline is a little defeat.
The hours, minutes and seconds stand as visible reminders that your effort put them all there. Preserve until your next run, when the watch lets you see how Impermanent your efforts are.
The Chip also reduces the damage done by bandits. They still steal drinks and cheers along the course, but no longer scramble the paying runners' results. No entry fee, no Chip, no time or place.
