Panerai Luminor Marina Automatic White Gold (PAM00180)

With its automatic Panerai P.9000 movement, its Luminor 1950 case in Panerai Composite and its strict adherence to the functional and aesthetic codes which make every Panerai watch unique, the Luminor Composite Marina 1950 3 Days Automatic - 44mm is a classic example of Panerai's tradition for innovation and quality.

The Luminor 1950 case and the bridge protecting the winding crown are executed in Panerai Composite, the synthetic ceramic, used in haute horlogerie for the first time by Officine Panerai, which is created by an electro-chemical process involving the transformation of aluminium. Panerai Composite is much lighter than ceramic but at the same time it is much harder and more resistant than steel, furthermore it is matt and extremely distinctive in appearance.

The large, unadorned brown dial is of a sandwich construction consisting of two superimposed layers containing the Super-LumiNova® which forms the fluorescent figures and hour markers. It is in the classic Panerai style, reflected by its thickness and high legibility even in the dark. The dial is protected by a sapphire crystal with anti-reflective treatment.The P.9000 automatic movement, which can be observed through the smoked sapphire crystal case back, is 13 ¾ lignes in diameter and 7.9 mm thick and it has been entirely designed and constructed within the Officine Panerai manufacture at Neuchâtel. This calibre has a date function, small seconds at 9 o'clock and a power reserve of three days, achieved by two spring barrels connected in series, with an oscillating rotor which winds the springs in both directions.

The Luminor Composite Marina 1950 3 Days Automatic - 44mm is water-resistant to 30 atmospheres (about 300 metres) and it is supplied with a strap of antiqued brown leather, with a Panerai Composite buckle of the same colour. Identified by the reference PAM00386, it is part of the Contemporary collection.

Calibre P.9000

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.
