This "numerical" complication is unusual in that it displays the digits for the hours
in a large, fixed window. The hour hand is replaced by a rotating disc on which the
hour digits are printed. The figures jump instantly when the hour changes. The
window, located at 12 o'clock, is perfectly aligned with the single central minute
hand and the power reserve indicator at 6 o'clock, arranging the information by
order of importance. The power reserve indicator becomes particularly useful since
the mechanism triggering the "jump" in the hours requires power. It gives the user
an indication of the remaining power, which is vital for the smooth functioning of the
movement. This indicator is displayed in an easily legible window at 6 o'clock.
The black triangle which sweeps this zone is fastened to the barrel, whose tension
is proportional to the power reserve mechanism. The power reserve is highest when
this index points to the right of the window (HAUT). When the index points to the left
(BAS), the watch stops since it no longer has sufficient mechanical energy. Please
note that the watch's accuracy may vary when the index is in the last "left-hand
quarter" of the semi-circle (BAS) corresponding to the last 10 hours of operation.

general uSage

Winding. When the watch has stopped (crown in position 0): wind the mechanism
by turning the crown clockwise. After about 40 rotations, the watch is fully wound
(the mechanism has no stop in order to keep the winder from being wound too
tightly). The power reserve triangle points right and indicates "HAUT" correspond-
ing to maximum power. The operating time is then about 40 hours.
When the watch is being worn , winding takes place automatically.
Setting the time. Pull the crown into position 1. Set the time by turning the crown
in the desired direction. The hour disc is designed to "jump" i.e. "move to the fol-
lowing hour" between the 59th and 60th minute (representing one minute of toler-
ance). The mechanical movement that activates the hour change is reversible: the
user is able to return to the previous hour by turning the crown clockwise (which
rotates the minute hand counter clockwise). The "jump" of the hour disc is then
postponed by approximately 10 minutes.
imPOrtant
Once the watch has been completely set, in order to guarantee perfect water-
resistance, push the crown back into position 0. The crown must never be handled
underwater.
maintenance
After being immersed in seawater, it is recommended to always rinse off the watch
and its strap with fresh water. We also recommend that you check that your watch
is still watertight every two years. In order to guarantee service compliant with the
brand's requirements, any servicing on your watch must be carried out by the Bell
& Ross repair center or by a watchmaker approved by Bell & Ross. For any repairs
under warranty, you will need to present the Bell & Ross warranty card, duly dated
and signed by the retailer at the time of purchase.
