Panerai Radiomir California 3 Days (PAM00424)

Officine Panerai presents a new Special Edition in Panerai Composite, the synthetic composite used in haute horlogerie for the first time by Officine Panerai and produced by an electro-chemical process of transforming aluminium. The new Luminor Composite 1950 3 Days - 47mm combines the characteristics and performance of this material, exceptional for its lightness, strength and durability, with the new hand-wound P.3000 calibre, entirely designed and produced in the Officine Panerai manufacture in Neuchâtel.
The Luminor 1950 case in Panerai Composite is 47 mm in diameter, a classic size for Panerai watches, and it has a matt brown appearance of great evenness. Made of the same material are the bridge protecting the winding crown with the classic clamping lever and the round bezel which surrounds the sapphire crystal with anti-reflective treatment. Water-resistant to 100 metres, the case has the polished crystal back which enables the movement to be seen.The sandwich dial too is dark brown and stripped to essentials with the characteristic small seconds dial at 9 o'clock. The dial is of sandwich construction, being formed of two thin metal discs, the upper one of which is perforated to allow the luminous substance placed between them (Super-LumiNova®) to be seen. The hands are also covered with the same luminous substance, in a special ecru colour so as to reproduce the vintage appearance of the dials of the period.
The movement used in the Luminor Composite 1950 3 Days - 47mmis the manufacture P.3000 calibre. With a diameter of 16½ lignes and hand-wound, the movement has a structure with large bridges, comparable to plates, while from the technical point of view it has two spring barrels, ensuring a power reserve of 72 hours (three days), and a large-diameter balance wheel with adjusting screws.Identified by the reference PAM00375, the new Luminor Composite 1950 3 Days - 47mm is produced in a unique numbered edition of 2,000 examples and it is supplied with a leather strap, closed by a buckle made of Panerai Composite.

Calibre P.3000Entirely designed, developed and produced in the Officine Panerai Manufacture in Neuchâtel, the hand-wound P.3000 calibre presents the main characteristics of the Panerai movements both in terms of structure and in terms of performance, robustness, accuracy and its long power reserve.

The thickness of the calibre P.3000 is 5.3 mm and the diameter is 16½ lignes, a substantial size which traces its origins from that of the movements which were fitted to the historic Panerai models. The calibre is immediately recognisable by its construction, which is similar to that of a three-quarter plate movement: a large bridge, next to another smaller one, covers the majority of the mechanical parts and it is fixed to the bottom plate by a series of screws of substantial thickness, thus forming a particularly rigid structure.

The movement has 21 jewels and it uses two spring barrels connected in series. Such an arrangement enables long, thin springs to be used, which ensures the delivery of a more even force and also does so over a longer period of time, with a power reserve of 3 days. The balance wheel is unusually large (13.2 mm) and it is the variable inertia type, with four adjusting screws arranged externally round the ring, so that the rate can be regulated without it being necessary to remove the whole assembly. Supported by a bridge with twin supports - a fixing much safer and more stable compared to the cantilevered single bridge - the balance wheel oscillates at a frequency of 3 Hz, equivalent to 21,600 alternations per hour. It is fitted with an Incabloc® antishock device and is free-sprung, so there is no regulating lever.

With brush-finished bridges and chamfered angles - that is, with the angles smoothed and polished - the P.3000 calibre is also fitted with the device for the rapid adjustment of the time: a star wheel with 12 points and a small spring clutch enable the hour hand to be moved one hour at a time, without interfering with the movement of the minute hand or the operation of the watch.
