Panerai

Florentine house of military dive instruments; Italian design, Swiss manufacture in Neuchâtel, defined by the Luminor and Radiomir cases.

Founded 1860 in Florence; supplied instruments and dive watches to the Royal Italian Navy for decades under military secrecy.
The crown-protecting bridge of the Luminor is its most recognisable device.
Modern in-house era began at the Neuchâtel manufacture with the P.2002 calibre (2005).
Extended power reserve has been a house theme since the Angelus SF 240 era of the 1950s.
