http://www.thewatchbox.com Any watch named after the lethal Italian Navy "Siluro a Lenta Corsa" manned torpedo had better be a seriously heavy hitter. The Panerai Radiomir S.L.C 3 Days PAM 449 - one of only 750 manufactured - delivers. At the onset of World War II, Officine Panerai's combat dive watches, like the Italian pioneering special forces that employed them, were entering their second generation with the benefit of lessons learned during early trials. Previous "California" half Roman/ half Arabic dials were visible but remained too busy for no-nonsense combat gear. Panerai responded by issuing a watch in the image of the PAM 449 seen here. The second-generation "3646," as the early Panerai combat watches were known in naval terms, were pared down the the bare minimum; dot and baton indexes. These were the watches that went to war, and these were the Panerai on the wrists of the men who fought battleships barehanded at Alexandria in December 1941. War stories aside, Parent's modern tribute to that WWII veteran comes in the form of the Radiomir S.L.C. 3 Days PAM 449. It takes the key features that defined the look and functional elegance of the original, but it adds luxury refinements befitting Panerai's modern status as a watchmaker of reference. The tribute begins with an acrylic crystal. Rendered in the same plexiglas compound as the original, the PAM 449's "plexi" also creates the same endearing distortion around its periphery that endears vintage watches to collectors of "bubble"-capped old-school divers. A faithful rendition of the famed stick-and-dot dial takes center stage. Its simplicity continues to tug at the heartstrings of watch enthusiasts who feel the emotional pull of Panerai's blue-collar, standard issue roots. Beautiful heat-blued hands ensure that the PAM 449's dial finishes with a flourish. Within the case, a modern Panerai P. 3000 movement keeps the beat at 21,600 VpH in the charismatic cadence of an old-fashioned pocket watch. For that matter, the sprawling bridges, large train wheels, giant balance, and simple architecture are an engineering homage to the Rolex pocket watch movements that powered the original Panerai 3646; even at the level of its movement aesthetic, this PAM 499 is designed with its tribute mission in mind. However, a three-day power reserve, independent hour setting (for frequent flyers' time zone jumping) shock-resistant free-sprung balance, and rugged full balance bridge mean that history has been checked at the door in places where discreetly-hidden modern watchmaking tech can offer real benefits.
