Panerai watches were created to face the darkness of the night and of the depths of the sea: these were the conditions under which the special underwater forces of the Royal Italian Navy operated, as they carried out missions which demanded extraordinary courage and heroism but also exceptionally durable and reliable equipment. It was in the 1930s and 1940s of the last century that the Italian Navy nominated Orologeria Panerai in Florence, with which it had already collaborated for many years, as its trusted partner for supplying underwater watches for the frogmen. To satisfy the strict requirements imposed by the Navy, the workshop of ideas created by the Panerai family developed a timepiece and other precision instruments embodying innovative technical solutions of genius and revolutionary simplicity, solutions which transformed those watches into an icon and which still today make every Panerai watch immediately recognizable.
