CHRONOGRAPH
The Patek Philippe rattrapante chronograph al-
lows you to measure the duration of events,
record lap times. These measurements are per-
formed with the two large sweep stop hands – the
chronograph and rattrapante hands – and with
the small 60-minute counter at 3 o'clock. Unlike
most split seconds chronographs, the Ref. 5950
is a three-phase chronograph that requires only
two pushers.
Actuating the pusher in the winding crown se-
quentially activates the three following com-
mands:
1. Simultaneously start the chronograph and
rattrapante hands,
2. Simultaneously stop the chronograph and
rattrapante hands,
3. Reset the chronograph and rattrapante hands.
Note: To avoid chronograph start problems, we recom-
mend that you postpone the use of the chronograph for 2
minutes after having set the time.
The pusher at 2 o'clock controls only the rattrapante hand.
MEASURING DURATIONS AND STOPPING LAP TIMES
When the event to be timed begins, actuate the
pusher in the winding crown: The superposed
chronograph and rattrapante hands begin to run.
To measure a lap time, press the pusher at 2 o'clock:
The rattrapante hand will stop but the chronograph
hand keeps running. Now you can take a note of
the lap time. When you actuate the pusher at 2
o'clock again, the rattrapante hand will catch up
with the chronograph hand and both hands, now
superposed, will continue running. This function
can be activated as many times as you wish. To stop
the final time, actuate the pusher in the winding
crown: this will stop the chronograph hand and
you can take a note of the duration of the event.
When you actuate the pusher in the winding crown
again, the chronograph and rattrapante hands will
both return to zero.
Caution: To reset the chronograph and rattrapante hands
to zero at the same time, they must be superposed. If the rat-
trapante hand is still indicating a lap time, actuate the pusher
at 2 o'clock to make it catch up with the chronograph hand,
and then reset both hands to zero by actuating the pusher in
the winding crown.
