Create a watch with a second hand only, no minute or hour hand. Essentially a very simple continuously running stopwatch (that doesn't stop), for people who need just that function. (They get minute-resolution time from a cell phone, for example.) The simplicity allows it to be constructed more cheaply than a traditional watch, no need for 60:1 gears.
Inspired by a doctor needing to measure pulse.
