The Radiomir 1940 3 Days GMT Oro Rosso has an elegant case in 18K red gold and a brown dial. But the PAM00570 also has an ingenious reverse side: the hand-wound P.3001 calibre is visible through a specially designed window, set in the back of the case. The watch also has a second time zone, date and small seconds.
In the 1940’s Guido Panerai directed his watchmaking workshop in Florence to make further improvements to the PANERAI Radiomir 1940, in order to meet the increasing demands of the Italian navy. As a result, the watch was given robust strap attachments and a large, cylindrical crown. This version of the PAM 570 retains both the functional details and the distinctive Italian design of the 18K red gold original.
The non-corrosive property of gold makes it an ideal precious metal for watchmaking. The PAM 570's case is 47mm in diameter and is made of 5Npt red gold, including a percentage of titanium. This guarantees high mechanical resistance. PANERAI uses this special red gold alloy because it makes the case extremely robust, and yet also provides symbiosis with the improved Radiomir of the 1940’s. Some added copper provides an intense warmth, which harmonises perfectly with the brown of the dial.
The dial, with its fine sunburst decoration, makes the functions easy to read. Moreover, its sandwich construction adds to visibility through a layer of fluorescence, which gives depth to the markings. The date is at the 3 o'clock position and the small seconds is to be found directly opposite, in keeping with the tradition which started at the end of the 1940’s. The second time zone indicator is in the centre. This function is especially useful for long journeys and for international communication across different time zones.
On the back of the PANERAI PAM 570, there is a window revealing the sophisticated mechanical P.3000/10, with three days power reserve and a Glucydur® balance which achieves 28,800 alternations/hour. In this version of the calibre, the bridges and the two spring cases are hollowed out, revealing the intricate workings of the inner components. The quality of the watchmaking can be seen in the angled and polished edges and the perlée decor on the plate. The colour of the machinery is echoed in the curved power reserve indicator - a very useful feature on this hand-wound watch.
