Split and Lap Timing in Practicals
Lap timing records each interval on its own while the watch keeps running, which suits counting successive swings of a pendulum or timing each stage of a slow reaction. Split timing holds the display at a chosen moment so the reading can be noted while the total carries on underneath. In a rate-of-reaction practical, start the watch as the reagents are mixed and stop it when the change appears, such as a cross under the flask vanishing from view.
Between experiments it works as an ordinary clock with the date and day.
