Using the tachometer

The tachometric scale associated with the chro-

nograph function enables speed read-off. Engage 

the chronograph (START) and stop the chronograph 

after 1 kilometre

 (STOP). The value indicated by the 

chronograph hand on the tachometer scale corres-

ponds to the average speed over 1 kilometre.  

If the time lapse between (START) and (STOP) equals 

20 seconds, the average speed – read on the tacho-

meter scale – is 180km/h (fig. 1). 

If the lapse is 30 seconds, the average speed is 

120km/h (fig. 2).

If 40 seconds were needed to cover one kilometre, 

the average speed would be 90km/h (fig. 3).
