Panerai Luminor Submersible 1950 3 Days Auto Bronzo

A powerful, fascinating reminder of the sea makes the new Special Edition Luminor Submersible unique. This professional underwater watch is the development of the model made by Officine Panerai more than half a century ago for the commandos of the Egyptian Navy.

The new Luminor Submersible 1950 3 Days Automatic Bronzo – 47 mm is actually made of bronze, one
of the materials associated since antiquity with the world of the sea.
Bronze is an alloy based on copper and one other metal, usually tin, to which other elements can
be added to achieve particular performance. The bronze chosen by Officine Panerai for the case
of the new Luminor Submersible is CuSn8, an alloy of copper and pure tin very resistant to
corrosive action by sea water and atmospheric agents. As well as its high degree of structural
strength, this material preserves the warm shades of the original while acquiring over time the
aged appearance through the patina which covers it. This patina is the result of the reaction of the
bronze to external agents (air, humidity, heat and wear) and it does not alter the properties of the
material but is rather a sign of its ageing, making each example unique and personalised.
The brushed bronze case, 47 mm in diameter, is water-resistant to 300 metres and has a
unidirectional rotating bezel with ratchet click and graduated scale for calculating the times of
immersion, with raised studs for reference. The characteristic bridge protecting the winding crown,
with the lever ensuring perfect water-resistance of the crown itself, is also made of bronze. The
sapphire back is fixed to the caseband by a ring of titanium, a metal chosen for its hypo-allergenic
qualities.

The dial follows the characteristic appearance of the Luminor Submersible, with bar markers
applied in place of the figures 12 and 6, but it is executed in an unusual dark green colour which
goes well with the bronze colour of the case. Protected by a sapphire crystal, the dial has skeleton
hands which are highly luminous, the little dials of the small seconds at 9 o’clock and, in a
symmetrical position, the window with the date.

The movement of the Luminor Submersible 1950 3 Days Automatic Bronzo – 47
mm is the automatic P.9000 calibre, entirely designed and produced in the Officine Panerai
manufacture in Neuchâtel. The P.9000 calibre has a structure with a three-quarter plate, clearly
visible through the transparent caseback, a diameter of 13¾ lignes and two spring barrels which
provide a power reserve of three days.

Identified by the reference PAM00382 and produced in a limited edition of 1.000 units, the
Luminor Submersible 1950 3 Days Automatic Bronzo – 47 mm is completed by a
leather strap, treated in such a way as to have an appearance similar to that of the period models
and fitted with a personalised titanium buckle.

The P9000 Movements:

The P.9000 automatic movement, entirely designed and created in the Officine Panerai
Manufacture in Neuchâtel, has a diameter of 13¾ lignes and a thickness of 7.9 mm. The three
versions available – P.9000, P.9001 and P.9002 – have the date at 3 o’clock and the small
seconds at 9 o’clock. They are distinguished by the variable inertia balance wheel, that is, one in
which the adjusting screws are arranged radially, and is the single base balance cock. The
frequency of oscillation is 28,800 alternations per minute, equivalent to 4 Hz, and the balance
wheel is free-sprung.
The power reserve is 3 days, achieved by the two spring barrels connected in series, the second
of which has a slipping spring. The use of two spring barrels means that long, thin springs are used
which provide a very even force. The evenness with which the force is delivered translates into
very accurate timekeeping in that it keeps the oscillation of the balance wheel at a constant
amplitude. The oscillating weight winds the springs as it rotates in both directions.

The system which supervises the rapid adjustment of local time is the same as that used in the
P.2000 calibres: a star wheel with 12 teeth and a small spring clutch enables the hour hand
indicating local time to be moved in clicks of one hour at a time, without interfering with the
movement of the minute hand or the running of the watch.
An innovative device enables the automatic winding system to be disconnected when the watch
is being wound by hand: this is arranged by a moving intermediate wheel which can adopt two
different positions. When the winding crown is rotated, the wheel moves and engages a wheel
beneath it with the teeth of the first spring barrel; but when it is in automatic winding mode, it is
the spring barrel which, as it rotates, moves the intermediate wheel and disconnects the
engagement with the wheel below and therefore the connection with the winding stem.
