The PAM00573 Radiomir 3 Days Automatic 1940 Oro Rosso led the progress of watch manufacturing in the 1940’s, as it does now with a new, automatic-movement generation. Due to the small diameter of its P.4000 movement, the watch features an exceptionally slim case for maximum wearer comfort – in fact the 18K red-gold case of this versatile timepiece measures just 45mm.
Guido Panerai originally pursued the implementation of a precision chronometer measuring exact seconds for marine use. These developments resulted in a distinctive design, which Paneristi worldwide have come to associate with longevity and precision.
The model PAM 573 has all the characteristic features of a diving watch. The Radiomir 1940 case was a revised version of its historical predecessor, the Radiomir 1936. Thus, the case and strap lugs were both fashioned from one solid block, thereby imparting great resilience to the structure. The case of the PAM 573 is an alloy of 18K red gold, and its deep colouring reflects an increased copper content. A trace of platinum has also been added to protect the precious metal from corrosion, and thus improve its durability. This highly polished case conveys a strong sense of Italian style with its design based on premium quality and elegant lines. The watch is guaranteed water-resistant up to 5 bars of pressure.
The sandwich dial is formed by two overlapping discs with a fluorescent substance between. Even in unfavourable light conditions, this allows the hour and baton markers to remain clearly visible through slots cut in the matt brown dial, whilst a large, polished bezel secures the anti-reflective sapphire crystal protecting the dial. Ever since the 1940’s, the small seconds have appeared on a separate dial at the 9 o'clock position, and this detail has been preserved in the PAM00573, together with the minimalist design. A brown alligator-leather strap with contrasting bright stitching adds the finishing touch.
The ultra-modern, automatic mechanical calibre P.4000 can be glimpsed through a glass caseback. This Neuchatel-developed movement is equipped with an off-centre micro-rotor. Because of the location and small size of the rotor, it has been possible to integrate a 22K red gold flywheel for this particular calibre. As a result, the movement is just 3.95-mm thick and fits nicely inside the PAM 573's flat Radiomir 1940 case. A Glucydur® balance and a KIF Parechoc® anti-shock device are included to complete the specification and preserve the customary OFFICINE PANERAI performance standards. The calibre beats at 28,800 vibrations/hour, and has a power reserve of three days. This timepiece features an advanced winding technology housed in a very flat red-gold case.
