Setting The Time, Adjustments, Special Notes, Maintenance - Pierre DeRoche PDR 4020 Mode D'emploi

Starting and adjusting the watch
1. Loosen the winding-crown by turning it counter-clockwise.
2. Using the thumb and forefinger, wind the watch manually by
making around 30 clockwise turns of the crown in position "A".
The watch will subsequently be automatically rewound by your
wrist movements.
3. Pull the winding-stem out to position "C" (the movement stops)
and rotate the crown counter-clockwise until hand "5" points to
2 am (24-hour scale).
4. Press the winding-stem back to position "B"; rotate the crown
counter-clockwise until the date changes and the central hands
"1" and "2" indicate 2 am (12-hour scale). The time display is now
synchronised.
5. Press the fast date adjustment push-button "7" until the correct
date is indicated by hand "4".
6. Pull the winding-stem out to position "C" again; turn the crown in
the required direction until the correct time is displayed.
7. Push the winding-stem back into position "A" (the movement
starts running again). Press the crown gently towards the case and
tighten the crown by rotating it clockwise.
Time-zone adjustment
When travelling in a geographical region with a time-zone difference
from the country of residence, unscrew the crown and pull it out to
position "B". Then display the time in the destination country by
rotating the crown in the appropriate direction.
The time of the second time zone is adjusted in successive one-hour
increments, without stopping the movement.
