Reading the Two Dials
The long sweep hand counts seconds on the main dial, while the small dial counts minutes from 0 to 60. Add the two readings: 2 on the small dial and 10 on the main dial means 2 min 10 s have passed.
Push the left-hand lever to start and again to stop, note the reading, then press the right-hand lever to send the hands back to zero for the next run.
Spring Drive and Timing Range
One complete winding keeps the clock going for about 30 hours, so it needs no battery and runs through a full day of practical classes. With one-second steps it suits intervals of tens of seconds or more, such as timing twenty swings of a pendulum or reading the temperature of cooling water every minute. Short, fast events are better timed electronically.
