http://www.thewatchbox.com Black watches are cool until they scratch. But a black ceramic watch can fix that problem fast. And a black ceramic Panerai Luminor PAM 317 chronograph GMT combines the best of both worlds with cool complications and exclusivity. This tongue-twisting Panerai Luminor 1950 Chrono Monopulsante 8 Days GMT Ceramica PAM00317 is one of the most feature-dense luxury watches money can buy. As one of only 500 units produced, it's also exceptionally exclusive. Zirconium ceramic is a modern industrial material that combines the hardness of sapphire crystal with the solid colors of PVD metal. Just as sapphire watch crystals will retain like-new appearance for decades, a ceramic case is hard enough to bring the same durability to the rest of a luxury timepiece. While Panerai watches aren't known for high horology complications, this watch, this PAM 317 features a mono pusher chronograph, a second time zone with an AM/PM indicator, a hacking movement, an eight-day power reserve with gauge, and a free-sprung balance that laughs at shock-induced error. Moreover, this PAM 317 features a "near-tuttonero" blackout treatment that includes all brides and plates of the P.2004 movement. A matching dial, bezel, case, crown guard, suede leather strap, and titanium PVD buckle complete the effect. As with all Panerai watches, swapping the strap changes the look and character of the watch. This PAM 317 Luminor 1950 Chrono features all Panerai factory accessories including the critical jeweler's tool and accessory rubber Panerai factory strap. All books, papers, and factory boxes are included with the purchase; this is a complete set. The Panerai Luminor 1950 Chrono Monopulsante 8 Days GMT Ceramica PAM00317 is a sports watch from the "dark side." Join it on thewatchbox.com. Video and content by Tim Mosso.
