With the new Radiomir 8 Days Ceramica - 45mm, Officine Panerai presents the combination of a high-tech material - ceramic and a Panerai movement entirely developed and produced in the manufacture in Neuchatel: the hand-wound P.2002/3 calibre. The Panerai hand-wound P.2002/3 calibre has a power reserve of eight days and it is notable for its three spring barrels and the linear power reserve indicator on the dial. As well as the date at 3 o'clock, the calibre also has the device which enables the hour hand to be rapidly adjusted without interfering with the movement of the minute hand.
