The impressive 47mm Panerai PAM 331 GMT tourbillon was just announced by Officine Panerai at SIHH 2009. This titanium model features a black dial, a black alligator strap, and the gorgeous 1950 Luminor case.

The PAM331 is equipped with Officine Panerai’s P.2005 calibre hand-wound mechanical movement, measuring 9.1mm thick. The P.2005 is an in-house movement that features 31 jewels, 16 1/4 lignes, 3 spring barrels, KIF Parechoc anti-shock protection, Glucydur balance, and a 6 day power reserve. It produces 28,800 alternations per hour.

The functions supported by the PAM 00331 include hours, minutes, seconds, tourbillon, 24 hour indicator, second time zone (GMT), and a power reserve indictator displayed on the back of the watch.

Panerai used sapphire crystal to cover both the dial and the see-through display back. The Panerai PAM 331 is water resistant to 100 meters.
