Eberhard Tazio Nuvolari Grand Prix TN User manual

T he Eberhard & Co. watch manufactory was founded
by Georges-Emile Eberhard at La Chaux-de-Fonds back
in 1887. Ever since, the venture has specialised in the
making of chronographs.
In this capacity, it has attained a highly respected
position in the world of high-grade watches. With the
introduction, at a later stage, of sportively elegant
watches it has furthermore augmented this status of the
Eberhard & Co. brand name.
Eberhard’s success story is backed by consistent
deployment of advanced technology, meticulous
craftsmanship and, not least, by observing that long
tradition of superior workmanship which has made
Swiss watchmaking a household name.
Today, with well over a century gone by, watches by
Eberhard & Co. continue to stand for that high-grade
quality and those excellent virtues which will please
even the most demanding of connoisseurs.

With this precious limited edition of 999 pieces the Maison Eberhard & Co. pays homage to the
memorable “Flying Mantuan” and to the world of races and vintage cars.
The “Tazio Nuvolari Edition Limitée Grand Prix TN 2010” is a modern and sophisticated chronograph,
whose dominant chromatic white tone characterizes the ceramic bezel, the engravings on the caseback
and the alligator strap, further enlivened by red stitching. The details are unmistakable: black dial with
large Arabic numerals, and flange with black or treatment and circular-grained finish. On the dial, the
unique and exclusive symbol of the driver: a stylised tortoise personalized with the initials “TN”, as
expression of the deep-rooted values of the sportive motor racing. On the dial, the unique and exclusive

USE OF THE CROWN
DIRECTIONS FOR USE OF WATER-RESISTANT WATCHES
The “Tazio Nuvolari Edition Limitée Grand Prix 2010” model resists unintentional contact with water (rain
or small splashes), but it is not fit for swimming, plunging or diving activities. Important: do not pull out
the crown nor activate the pushbuttons as long as the watch is wet. We strongly recommend that you have
the water-resistance checked at least once a year by a qualified technical service facility in order to find out
if the gaskets need to be replaced.
POSITION A - Screw-in crown. In this position water-resistance guaranteed
POSITION B - To unscrew the crown, turn it counter-clockwise.
Position for hand-winding the movement
POSITION C - Neutral position of the movement
POSITION D - Time setting

PUSHBUTTONS
Make sure pushbuttons are always pressed in following order:
A: start
A: stop
B: return to zero
Abide by this sequence quite severely so as to preclude damage to the mechanism.
Don’t activate the pushbuttons under water since they are not watertight while being pressed.
OPERATING INSTRUCTIONS FOR THE CHRONOGRAPH
Press pushbutton A to start the chronograph. Press it again to stop it. This will make it possible to read
the counters (seconds, minutes and hours elapsed). Press pushbutton
A again and the chronograph will
function again after the intermediate stop. To reset to zero, the chronograph must be in the stop position
and, by pressing the second push button
B , all the hands will return to zero. You are recommended not
to have the chronograph mechanism running constantly.
TACHOMETER SCALE - TACHOMETER SCALE IN KM/HOUR - BASIS 1000 M - ON THE
DIAL
The outer rim on the dial shows the data needed for metering the speed of a vehicle over a distance of
1,000 metres. The moment the vehicle passes the first reading mark, the beginning of said 1,000 m
distance, activate the hand
F of the chronograph to start it and press again to bring it to a stop at the
moment the vehicle passes the second reading mark. Said hand
F will now indicate the average speed
reached in km/h in tune with the tachometer scale. Example: when one kilometre is covered within 45
seconds, the average speed displayed by the centre second-hand
F on the tachometer scale will be
tantamount to a speed of 80 km/h.
TACHOMETER SCALE IN MILES/HOUR - BASIS 1000 M - ON THE BEZEL
To measure the speed in miles proceed as explained above for the km/hour, but read the speed in miles
on the engraved scale on the bezel of the watch case. Example: if one kilometre is covered in 45 seconds,
the average speed indicated by the centre second hand of the chronograph on the tachometer scale is
49.7 miles per hour.
