DIVER DEEP DIVE
Ulysse Nardin plunges 1,000 meters underwater.
Ulysse Nardin’s links to the sea run deep. A recognized pio-
neer of watchmaking innovation since 1846, the Manufacture’s
early renown was built on the peerless precision and reliabil-
ity of its marine chronometers – essential navigational instru-
ments that helped seafarers determine longitude by means
of celestial navigation. The Manufacture is equally renowned
for what it has achieved underwater, with its solidly built and
unabashedly masculine Diver collection.
Like its immediate predecessor, the Diver Deep Dive is pow-
ered by the in-house caliber UN-320, which has a patented
silicium lever and escape wheel configuration. The balance
spring is also in silicium, a material Ulysse Nardin first intro-
duced to Haute Horlogerie.
Along with 1 km water resistance — the world record diving
depth is 701 meters — new technical standouts masterwork
include a removable titanium guard on the crown at 2 o’clock
and a helium release valve at 9 o’clock, for deep dives of pro-
longed periods of time or under saturation. The rubber strap is
a first: it has an expandable element that adjusts to changes
in wrist size during dives, caused by the compression of your
neoprene diving suit. The large bezel has 12-notched teeth for
easy manipulation, even with diving gloves.

Winding the movement: unscrew the crown
and turn the crown clockwise. If the watch has stopped,
approx. 30 turns will give enough power to provide
sufficient accuracy.

Important: do not use quick correction between
10:00 and 02:00; doing so may result in

DATE SETTING
Ulysse Nardin quick correction of the date can be effected back-
ward and forward.
Important note : To avoid damaging the gearing mechanism of the
movement, please do not change the date when the hour hand is
set between 10:00 and 02:00.
We suggest adjusting the hour hand at 6 o’clock before activating
the quick setting device in position B. Set the date on yesterday and
then turn the hour hand (position C) clockwise, passing by midnight.
The date will then correctly be set and you will be sure that the hour
hand is showing either AM or PM.
Push back and screw the crown to guarantee full water resistance.
TIME SETTING
Unscrew and pull the crown out to position C. To allow accurate
setting, the second hand will stop (stop seconds function). Make
sure the hands are properly showing either am or pm, otherwise the
date will change at noon instead of midnight. Push back and screw
the crown to guarantee full water resistance.
PRECISION
Precision and average daily rate depend on the activity of the
person wearing the instrument. Violent shocks or knocks should
be avoided to prevent shaking that may loosen certain parts.
