c) Flyback
At any time, a long press on P1 will restart timing from 0 (when the pushpiece is
released): this is the FLYBACK function. The seconds hand positions itself directly
on the active timing second.
d) Tachometer
When the chronograph has been stopped after a measured time, a short press on
P2 will display the average speed corresponding to the time measured – for a pre-
introduced distance (see chapter 10.f). The upper screen displays
SPEED
, and then
the speed unit; the lower screen shows the value of the speed. The display of the
speed lasts about 5 seconds and then reverts to the preceding display.
e) Converting units of speed
When the speed is displayed, the unit can be changed, thus converting it, as fol-
lows:
• When the speed appears, pull the crown to position 2 (
CONVERT
)
• Change the units by turning the crown (see figure 2)
• Press the crown into neutral position 1. The speed is automatically expressed in
the new unit.
