Panerai Radiomir Replica Watches: Panerai Radiomir is highly sought-after by many avid Panerai collectors.It was revealed to the First Submarine Group of the Royal Italian Navy in 1936. Before its release, Panerai had spent several years experimenting with luminous materials in the hopes of creating a watch that could be relied on in the dark. After extensive research, they found that a combination of zinc sulphide and radium bromide proved to be the most successful and decided to call this line “Radiomir.” After being presented to the Italian Navy, the soldiers praised its performance and durability. During WWII, the Panerai Radiomir was the watch of choice for the Italian divers diving in the Mediterranean Sea. Lieutenant Luigi Durand De La Penne was involved in several high profile attacks and always wore his Panerai Radiomir during these escapades. As the lieutenant’s popularity rose, so did that of his watch.
