SPECIAL CHARACTERISTICS

USING THE TACHOMETER
1 2
The tachometer is the graduation on the dial or flange of your Breitling chronograph
enabling you to determine average speeds or hourly productivity rate, based on an
observation period of less than 60 seconds.
1. Average speed
Using the chronograph to measure the time required to cover a kilometer or a mile. The final
position of the second hand indicates the average speed. If it takes 20 seconds to cover
1 km or 1 mile, the scale respectively indicates an average speed of 180 km/h or 180 miles/h.
2. Hourly productivity rate
Measuring the time required to produce 1 unit. If the chronograph is stopped at 40 seconds,
the tachometric scale indicates 90, corresponding to an hourly productivity rate of 90 units.
