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.

Edition Vitrée
In the history of watchmaking, one important stage came under the name of Extra-fort: a chronograph created by the
house of Eberhard & Co., at the end of the war. It immediately became a watch symbol of the 50s and it has retained its
status of coveted collector’s piece until today.
The new millennium combines tradition and innovation: the Swiss company reinterprets this model and brings it up-todate. The new Vitrée version features a transparent case back enabling the elegant, precious movement to be admired.

FEATURES
Extra-fort Edition Vitrée has a mechanical movement and an automatic winding mechanism. The transparent sapphire
crystal case back reveals the elegant pearl-finish of the movement and oscillating mass, engraved with the ancient shield
and featuring a special “coiffe”, which houses the small rotor bearing. The timepiece has a screw-in crown, a domed sapphire
glass, and it is water-resistant to 5 atm.
Available with a steel case, Extra-fort Edition Vitrée is fitted with a crocodile leather strap or a “Chalin” steel bracelet.
READING THE DIAL
On the Extra-fort Edition Vitrée dial there are 2 counters which have the following functions:
– Small continuous seconds-hand
F
– 30-minutes chronograph register-hand
H
The chronograph seconds are given by the centre-hand
G
The calendar is situated at 6.
DISTINCTIVE FEATURES OF THE MOVEMENT
Chronographic automatic movement, 28.800 vibrations/h 13 1/4”
– “Glucydur” balance for regulating the movement (the inoxidizable alloy of which has a low coefficient of expansion),
combined with a self-compensating spiral; it is hence insensitive to temperature fluctuations and ensures an optimum
regulation of the movement
– Regulator for line adjustment
– Numeber of rubies: 26
– 42-hours power-reserve (with non-inserted chrono)
– Oscillating mass featuring a pearl-finish and the “Extra-fort” engraving in blue; special “coiffe”housing the small bearing
of the rotor personalised by the symbolic “E”shield
– Movement with “décoré soigné”finish

POS. A -
Screwed-in crown, guaranteed water-resistance.
POS. B -
WINDING OF THE WATCH - To unscrew the crown turn it counter-clockwise.
When it is unscrewed, turn it clockwise to transmit the manual charge to the movement. If your
Extra-fort Edition Vitrée has not been worn for some time, the automatic movement has to be
winded manually, in order to obtain an immediate sufficient power-reserve and to ensure an
accurate working of the watch.
POS. C -
RAPID DATE-SETTING: Pull the crown to the first catch.
Turning the crown clockwise you will operate for setting the desired date.
IMPORTANT: Never make the correction of the date between 10 p.m. and 1 a.m.
POS. D -
TIME SETTING - Pull the crown to the second catch to set the time.
OPERATING THE CROWN
IMPORTANT
To set back the crown, push it lightly against the watch case while twisting it clockwise until it is fully screwed back in.

PUSH BUTTONS
Make sure push-buttons are always pressed in the following order:
A
: start
A
: stop
B
: return to zero
Abide by this sequence quite severely so as to preclude damage to the mechanism.
Never make use of the push-buttons under water since they are not watertight while being pressed.
OPERATING INSTRUCTIONS FOR THE CHRONOGRAPH
Press the push-button Ato start the chronograph mechanism. Press the push-button a second time to stop the chronograph
mechanism. You can now read on the counters how many seconds
G
and minutes Hhave elapsed. Press the push-button again
and the chronograph will restart from the intermediate stop. To return to zero, the chronograph must be in the stop position. Press
the second push-button
B
and all hands will return to zero. You are advised not to leave the chronograph mechanism operating
continuously.
HOW TO USE THE TACHOMETER SCALE
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 marking the beginning of said 1,000m distance, activate the hand
G
of the
chronograph to bring it to a stop the moment the vehicle passes the second reading mark. Said hand
G
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 seconds-hand
G
on
the tachometer scale will be tantamount to a speed of 80km/h.
1/5 SECOND SCALE
The division on the dial of this model Menables the user to make observations not just to approximately a second, but to
the order of 1/5 second.
DIRECTIONS FOR USE OF WATERTIGHT WATCHES
You may wear your “Extra-fort Edition Vitrée” when in the water or when taking a shower, but it is not fit for breath-held
diving, plunging or diving activities. Important: we strongly recommend that you have the crown well tightened before
possible contacts with water. Do not activate the pushbuttons nor manipulate the crown as long as the watch is wet or in
the water. After using in seawater, rinse the watch under fresh water. Exposure to temperature shocks should be avoided.
We 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.
