LIMITED EDITION
Commissioned in 1964 as one of the world’s first deep-ocean submersibles, the
Human Occupied Vehicle (HOV) Alvin remains one of the most state of the art
deep sea explorers today.
It is named after Allyn Vine, a noted engineer and geophysicist who helped
pioneer deep submergence research and technology.
By 2021 Alvin will have completed another overhaul, giving it the ability to dive
to a remarkable 6,500 metres, which covers 98% of the seafloor.
Alvin can hover and maneuver through difficult topography, or even rest on the
seafloor. This gives it the unique ability to perform research surveys and
observations to develop a better insight of what lays well, well below sea level.
This unique limited edition timepiece is a tribute to the remarkable engineer-
ing, durability and technique that has gone into one of our most useful tools for
understanding the mystery and majesty of the deep oceans.

This timepiece is equipped with a self-winding Mechanical Automatic
movement.
It does not need a battery. It is powered by the motions of the user’s own
wrist during the wear of the watch automatically. You may also choose to
wind the watch manually.
Before wearing your watch, make sure to wind it clockwise with 10 rotations
of the crown.
For good measure gently move the watch side to side around 30 times to see
the seconds hand run at its normal speed.
Please make sure to remember that during a period when you are not
wearing the watch, the power reserve of movement will wear down and you
will have to re-wind the watch again before wearing.

This watch is equipped with a screw down crown. Do not pull the crown
unless it is unscrewed rst.
PLEASE READ THE FOLLOWING BEFORE UNSCREWING THE CROWN
TO UNSCREW: Turn the crown anti-clockwise until it
turns freely without tension. Gently pull the crown out
to the other desired positions for watch setting (see
specic operating instructions on the following pages).
SCREW-DOWN CROWN
TO SCREW: Push the crown all the way in (towards the
watch) then begin to turn clockwise until it is securely
screwed down.
Note: Failure to securely screw down the crown after
setting the watch may affect its water resistance.

1. Pull the crown out to position 2 , its maximum extension. The second
hand will stop moving.
2. Turn the crown either clockwise or anti-clockwise until the watch hands
are positioned at the desired time.
3. When the desired time is reached push the crown back to position 1 and
screw down.
TIME SETTING

EN
This NUBEO timepiece is equipped with a Helium Release Valve.
It provides functionality for professional divers operating at great depths
for prolonged periods of time or under saturation.
When commercial divers operate at great depths, they often spend
prolonged hours in diving bells under pressure breathing a breathing gas
that contains the gases helium or hydrogen. Since helium atoms are the
smallest natural gas particles found in nature, these gas atoms are able
to work their way inside the watch, around any o-rings or other seals the
watch may feature. This is not a problem as long as the divers stay under
pressure, but when the decompression stops during resurfacing a pressure
difference builds up between the trapped gas inside the watch case and its
environment. Depending on the construction of the watch case and crystal,
this effect can cause damage to the watch, such as the crystal popping off.
HELIUM RELEASE VALVE
9
EN
The helium release valve does not need any manual intervention or
adjustment; it automatically releases the helium or hydrogen used in the
breathing gas mix trapped inside the watch case.
Please make sure to employ the screw-down crown on your timepiece for
maximum water protection.

All Nubeo timepieces are designed with a minimum water resistance rating
of 5 ATM (50m). The water-resistance of a timepiece protects the movement
from dust, moisture, and risk of damage to the movement should it be
immersed in water.
Please see chart for guidelines for the recommended exposure of various
water ratings.
It is important not to attempt to adjust the position of the crown while the
timepiece is in contact with water. Water can enter the case causing damage
to the movement.
For timepiece with screw-down crowns, it is important to ensure the crown
is in the proper position and completely locked before contact with water.
For timepieces with chronograph functions, do not engage the chronograph
under water, as water may leak in the case and cause damage to the
movement.
