Launched in 2006 to celebrate 30 years of the
Nautilus collection, your Nautilus with date, moon
phases and power reserve display is one of the few
sports watches to be equipped with complications. The
ultra-thin self-winding caliber 240 PS IRM C LU
movement drives these features with exceptional
reliability and extreme precision, earning the time-
piece the prestigious Patek Philippe Seal. Its refined
details, remaining faithful to the traditional values of
fine watchmaking (including bridges adorned with
Geneva waves, boasting a polished finish and beve-
led edges; a hand-finished circular-grained plate; and
a 22-carat gold mini rotor with Geneva waves and
an engraved Calatrava cross) are visible through a
sapphire crystal case back. Its horizontally embossed
dial – an iconic feature of the men’s Nautilus watch –
is distinguished by its unique geometry and unprec-
edented readability, boasting a pointer-type date
display at 7 o’clock with moon-phase aperture, a pow-
er-reserve display between 10 and 11 o’clock, and sub-
sidiary seconds between 4 and 5 o’clock. Boasting
side-mounted hinges reminiscent of those found on
marine portholes, and an unusual octagonal-shaped
bezel with rounded corners enhanced by alternat-
ing brushed and polished textures, the case is distin-
guished by a truly unique design: a cult model and
a timeless classic within the world of luxury sports
watches. Prestigious style combined with a sophisti-
cated mechanism.

INSTRUCTIONS
WINDINGCROWN
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
Your watch is equipped with a screw-down crown
that must be completely unscrewed before you can
perform any adjustments.
WINDING
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal mass
in motion; this tensions the mainspring, which stores
the energy. When you take off your fully wound
watch, it will continue to run for at least 38 hours.
When it has stopped after depleting the power
reserve, it can be rewound by hand (about 10 clock-
wise turns of the crown).

SETTINGTHETIME
To set the time, unscrew the crown completely,
pull it gently all the way out, and move the hands
in either direction. Once you have set the correct
time, push the crown home again and screw it down.
When you turn the hands clockwise beyond mid-
night, the calendar displays will advance as well. We
advise against turning the hands counterclockwise
across midnight because this would desynchronize
the calendar displays; however, it would not damage
the calendar mechanism.
Note: If your watch has stopped running, rst move the
hands clockwise until they pass 12 o’clock and the date
advances by one day (at midnight). Then set the correct
time. If it is past noon, move the hands forward beyond
12 o’clock again.

10
The crown must be completely unscrewed
before you can wind the watch or set the
time.
Please wind the watch and set the time before
you put the watch on. This prevents lateral
pressure on the winding stem. Please use
your fingernails to pull the crown out and
turn it gently between two fingertips.
Never pull out the crown in a humid envi-
ronment or underwater: the water resist-
ance of your watch is assured only when the
crown is pushed home and screwed down.
Correction push pieces should be actuated
exclusively with the correction stylus that
was delivered with the watch. The use of
any other tool could damage your timepiece.
If your watch has stopped running, rewind
it by hand before performing any correc-
tions or adjustments (about 10 clockwise
turns of the crown).
Do not perform any date or moon phase
correction between 9 p.m. and 1 a.m.
Every year, the date must be corrected five
times – at the end of each month that has
fewer than 31 days.
